2006-01-05 David Reveman * src/cairo-pdf-surface.c (emit_pattern_stops) (emit_linear_pattern, emit_radial_pattern): Track gradient changes. 2006-01-04 Carl Worth * Originally: 2005-10-10 David Reveman * src/cairoint.h: * src/cairo-image-surface.c: (_cairo_image_surface_set_matrix): * src/cairo-matrix.c: (_cairo_matrix_to_pixman_matrix): * src/cairo-pattern.c: (_cairo_gradient_pattern_init_copy), (_cairo_pattern_init_linear), (_cairo_pattern_init_radial), (_cairo_pattern_add_color_stop), (cairo_pattern_add_color_stop_rgb), (cairo_pattern_add_color_stop_rgba), (_cairo_linear_pattern_classify), (_cairo_pattern_acquire_surface_for_gradient), (_cairo_pattern_acquire_surface): Throw away old gradient code from within cairo-pattern.c in favor of using new support in pixman for gradients. * test/clip-operator-ref.png: * test/clip-operator-rgb24-ref.png: * test/gradient-alpha-ref.png: * test/gradient-alpha-rgb24-ref.png: * test/linear-gradient-ref.png: * test/linear-gradient-rgb24-ref.png: * test/mask-ref.png: * test/mask-rgb24-ref.png: * test/operator-clear-ref.png: * test/operator-clear-rgb24-ref.png: * test/operator-source-ref.png: * test/operator-source-rgb24-ref.png: * test/text-pattern-ref.png: * test/text-pattern-rgb24-ref.png: * test/trap-clip-ref.png: * test/trap-clip-rgb24-ref.png: * test/unbounded-operator-ref.png: * test/unbounded-operator-rgb24-ref.png: Update reference images for all tests involving gradients since the gradient output has changed slightly. 2006-01-03 Vladimir Vukicevic * src/cairo-glitz-surface.c (_cairo_glitz_surface_create_similar): Clamp surface dimensions to a minimum of 1. (_cairo_glitz_surface_get_image): Set the glitz clip to NULL before calling glitz_get_pixels, to return the full surface contents. Restore clip afterwards. (_cairo_glitz_surface_composite_trapezoid): Return UNSUPPORTED if the antialias is anything other than DEFAULT/GRAY. * src/cairo-image-surface.c (_cairo_image_surface_create_with_masks): Try to recover a standard cairo_format_t from given pixman format masks, so that various things that only work with a standard format work correctly. * test/cairo-test.c: Remove cairo_glitz_surface_write_to_png, replace with generic cairo_surface_write_to_png (since it works with image-surface create_with_masks fix) 2006-01-03 Vladimir Vukicevic * test/make-html.pl: Clean up output some; show only images that fail, otherwise just show pass/fail squares. 2005-12-30 Emmanuel Pacaud * src/cairo-svg-surface.c (_cairo_svg_surface_create_for_document): no more has_clip boolean. Init clip_level. (_cairo_surface_intersect_clip_path): a NULL path means reset of clipping region, not back to previous clipping level. 2005-12-28 Emmanuel Pacaud * src/cairo-svg-surface.c (_cairo_svg_document_create): namespace declarations for SVG and XLINK (#5411). 2005-12-27 Christian Biesinger * test/mask-beos-rgb24-ref.png: * test/mask-beos_bitmap-argb32-ref.png: * test/mask-beos_bitmap-rgb24-ref.png: * test/set-source-beos-rgb24-ref.png: * test/set-source-beos_bitmap-rgb24-ref.png: * test/trap-clip-beos-rgb24-ref.png: * test/trap-clip-beos_bitmap-rgb24-ref.png: Add BeOS-specific reference images for tests where the maximum color difference is 1. 2005-12-27 Christian Biesinger * src/cairo-beos-surface.cpp: Implement composite for the beos backend. Don't map CAIRO_OPERATOR_ADD to B_OP_ADD for now, something's broken there. 2005-12-26 Christian Biesinger * src/cairo-beos-surface.cpp: Don't require that the caller locks the view; do it in cairo code. * test/cairo-test-beos.cpp: Remove the now-unneeded locking 2005-12-21 Carl Worth * src/cairo-ps-surface.c: Remove some unneeded backend functions (composite, fill_rectangles, composite_trapezoids, old_show_glyphs). 2005-12-21 Carl Worth * src/test-meta-surface.c: * src/cairo-paginated-surface.c: Don't implement create_similar for the test-meta or the paginated surface. This was slowing things down a _lot_ (about 11× for the mask test for example) without any improvement in output quality. We can revisit this again later if there's any output improvement to be had down the road. 2005-12-21 Carl Worth * src/Makefile.am: * src/cairo-paginated-surface-private.h: * src/cairo-paginated-surface.c: (_cairo_paginated_surface_create), (_cairo_paginated_surface_create_similar), (_cairo_paginated_surface_finish), (_cairo_paginated_surface_acquire_source_image), (_cairo_paginated_surface_release_source_image), (_cairo_paginated_surface_show_page), (_cairo_paginated_surface_intersect_clip_path), (_cairo_paginated_surface_get_extents), (_cairo_paginated_surface_paint), (_cairo_paginated_surface_mask), (_cairo_paginated_surface_stroke), (_cairo_paginated_surface_fill), (_cairo_paginated_surface_show_glyphs), (_cairo_paginated_surface_snapshot): Add a private cairo_paginated_surface_t which builds on top of the meta surface and is intended to provide an easy interface with common functionality for the various paginated surface types (ps, pdf, etc.). * src/test-paginated-surface.c: (_test_paginated_surface_create_for_data): * src/test-paginated-surface.h: * test/cairo-test.c: (create_test_paginated_surface), (test_paginated_write_to_png), (cleanup_test_paginated), (cairo_test_expecting): Add test_paginated_surface_t which is another test surface enabled with --enable-test-surfaces. The test_meta_surface code served as the basis for cairo_paginated_surface_t so that test surface may be entirely superfluous now. 2005-12-21 Carl Worth Here is a cleaner implementation of the _cairo_array_t change which was previously committed inadvertently. * src/cairoint.h: * src/cairo-array.c: (_cairo_array_fini), (_cairo_array_grow_by), (_cairo_array_index), (_cairo_array_allocate), (_cairo_user_data_array_fini), (_cairo_user_data_array_get_data), (_cairo_user_data_array_set_data): Fix buggy implementation of _cairo_array_snapshot by changing array->elements to be a pointer to a pointer. This extra level of indirection allows the snapshot array to point to a pointer which will itself get changed when new storage is needed for a growing array. Previously, the snapshot would be left pointing at stale storage. * src/cairo-meta-surface.c: (_cairo_meta_surface_finish), (_cairo_meta_surface_replay): * src/cairo-win32-font.c: (_flush_glyphs): Fix to call _cairo_array_index rather than grabbing array->elements directly and casting (which cast is now wrong with the change in implementation of array->index). 2005-12-21 Carl Worth * src/cairoint.h: * src/cairo-array.c: (_cairo_array_fini), (_cairo_array_grow_by), (_cairo_array_index), (_cairo_array_allocate), (_cairo_user_data_array_fini), (_cairo_user_data_array_get_data), (_cairo_user_data_array_set_data): * src/cairo-meta-surface.c: (_cairo_meta_surface_finish), (_cairo_meta_surface_replay): * src/cairo-win32-font.c: (_flush_glyphs): Revert inadvertent commit (immediately previous). 2005-12-21 Carl Worth * src/test-meta-surface.h: Fix indentation. 2005-12-21 Carl Worth * src/cairo-meta-surface-private.h: Remove cruft from old commands that the meta surface no longer implements (composite, fill_rectangles, composite_trapezoids, and set_clip_region). 2005-12-21 Christian Biesinger * src/cairo-ft-font.c: (_cairo_ft_unscaled_font_create_for_pattern): * src/cairo-gstate.c: * src/cairoint.h: Fix some typos 2005-12-21 Emmanuel Pacaud * src/cairo-svg-surface.c (_cairo_svg_surface_create_for_document): store surfaces in a node, and clip to surface area. Now SVG backend should pass pixman-rotate test. (emit_composite_svg_pattern): emit transformation matrix. (_cairo_svg_surface_intersect_clip_path): don't use xmlBuffer here. 2005-12-20 Carl Worth * src/cairo-meta-surface.c: Add some comments describing what a cairo_meta_surface_t is. * src/test-fallback-surface.c: * src/test-fallback-surface.h: Remove unused _test_fallback_surface_create_for_data. * src/test-meta-surface.c: * src/test-meta-surface.h: Remove unused _test_meta_surface_create_for_data. Add missing source file src/test-meta-surface.h. 2005-12-20 Carl Worth * src/cairoint.h: * src/cairo-gstate.c: (_cairo_gstate_get_antialias): * src/cairo-surface-fallback.c: (_create_composite_mask_pattern), (_clip_and_composite_with_mask), (_clip_and_composite_combine), (_clip_and_composite_source), (_cairo_rectangle_empty), (_clip_and_composite), (_composite_trap_region), (_composite_traps_draw_func), (_clip_and_composite_trapezoids), (_cairo_surface_fallback_paint), (_cairo_surface_fallback_mask), (_cairo_surface_fallback_stroke), (_cairo_surface_fallback_fill), (_cairo_surface_fallback_show_glyphs): Move more fallback code from cairo-gstate.c to cairo-surface-fallback.c where it belongs. In the process, clean up the function names a bit and make the whole mess static. 2005-12-19 Carl Worth * src/Makefile.am: * src/cairo-surface-fallback-private.h: * src/cairo-surface-fallback.c: (_fallback_init), (_fallback_fini), (_cairo_surface_fallback_paint), (_cairo_surface_mask_draw_func), (_cairo_surface_fallback_mask), (_cairo_surface_fallback_stroke), (_cairo_surface_fallback_fill), (_cairo_surface_old_show_glyphs_draw_func), (_cairo_surface_fallback_show_glyphs), (_cairo_surface_fallback_snapshot), (_cairo_surface_fallback_composite), (_cairo_surface_fallback_fill_rectangles), (_cairo_surface_fallback_composite_trapezoids): * src/cairo-surface.c: (_cairo_surface_snapshot), (_cairo_surface_composite), (_cairo_surface_fill_rectangles), (_cairo_surface_paint), (_cairo_surface_mask), (_cairo_surface_stroke), (_cairo_surface_fill), (_cairo_surface_composite_trapezoids), (_cairo_surface_show_glyphs): Begin moving fallback code out of cairo-surface.c and into cairo-surface-fallback.c. 2005-12-19 Carl Worth * src/cairo-surface.c: (_cairo_surface_create_similar_solid): Use _cairo_surface_paint rather than _cairo_surface_fill_rectangle as only the former is guaranteed to work with all backends. * src/test-fallback-surface.c: Refine the comment describing this test surface. * src/Makefile.am: * src/test-meta-surface.c: (_test_meta_surface_create), (_test_meta_surface_create_for_data), (_test_meta_surface_create_similar), (_test_meta_surface_finish), (_test_meta_surface_acquire_source_image), (_test_meta_surface_release_source_image), (_test_meta_surface_show_page), (_test_meta_surface_intersect_clip_path), (_test_meta_surface_get_extents), (_test_meta_surface_paint), (_test_meta_surface_mask), (_test_meta_surface_stroke), (_test_meta_surface_fill), (_test_meta_surface_show_glyphs), (_test_meta_surface_snapshot): Add new test surface for exercising cairo_meta_surface. * test/.cvsignore: * test/cairo-test.c: (create_image_surface), (create_test_fallback_surface), (create_test_meta_surface), (cairo_test_for_target), (cairo_test_expecting): Simplify the image and test_fallback targets by not using create_for_data. Allow for NULL cleanup target functions. Add support for the test_meta_surface. 2005-12-20 Christian Biesinger * src/cairo-beos-surface.cpp: Use correct color when OPERATOR_SOURCE is used on a surface without alpha information. 2005-12-19 Keith Packard * src/cairo-clip.c: (_cairo_clip_intersect_to_rectangle), (_cairo_clip_intersect_to_region): * src/cairo-gstate.c: (_create_composite_mask_pattern), (_cairo_gstate_clip_and_composite), (_composite_trap_region), (_cairo_surface_clip_and_composite_trapezoids): * src/cairo-surface.c: (_cairo_surface_set_clip): Use NULL clip instead of special serial zero cairo_clip_t Should make using surfaces easier. 2005-12-19 Emmanuel Pacaud * src/cairo-svg-surface.c (_cairo_svg_surface_stroke): fix stroke linewidth and dashes, I hope. Emit stroke-dashoffset. 2005-12-19 Emmanuel Pacaud * configure.in: CAIRO_CAN_TEST_SVG_SURFACE depends on librsvg. * src/cairo-svg-surface.c: cairo_svg_surface_t owns a xml node, for support of svg_surface_composite. (_cairo_svg_surface_create_for_document): init xml_node. All surfaces except first one are stored in defs node. (emit_composite_image_pattern): returns pattern size, and don't call emit_transform if is_pattern == TRUE. (emit_composite_svg_pattern): do something. (emit_composite_pattern): returns pattern size. (_cairo_svg_surface_composite): xml_node is stored in cairo_svg_surface_t now. (emit_surface_pattern): emit surface pattern width here. Fix property names. (_cairo_svg_path_close_path): don't close path if no current point. (_cairo_svg_surface_fill_rectangles): new. (_cairo_svg_surface_fill): emit fill rule. xml_node is in surface now. (_cairo_svg_surface_composite_trapezoids): xml_node is in surface now. (_cairo_svg_surface_stroke): ditto. (_cairo_svg_surface_intersect_clip_path): ditto. Emit fill rule. * test/.cvsignore: ignore svg2png. * test/Makefile.am: build svg2png utility. * test/cairo-test.c (create_svg_surface): new. (svg_surface_write_to_png): new. (cleanup_svg): new. (cairo_test_expecting): test SVG backend if CAIRO_HAS_SVG_SURFACE && CAIRO_CAN_TEST_SVG_SURFACE. * test/svg2png.c: new. 2005-12-19 Christian Biesinger * configure.in: * src/cairo-beos-surface.cpp: Some final changes to the beos backend before checkin were wrong, fixing. 2005-12-19 Christian Biesinger * src/cairo-beos-surface.cpp: Use gtk-doc syntax rather than doxygen syntax for internal functions (to avoid warnings from gtk-doc when it processes this file) 2005-12-19 Christian Biesinger * INSTALL: Mention new --enable-svg option * README: Add notes for the new BeOS backend * configure.in: Add disabled by default BeOS backend * src/Makefile.am: Add BeOS files * src/cairo-beos-surface.cpp: New * src/cairo-beos.h: New * src/cairo-features.h.in: BEOS_SURFACE_FEATURE * src/cairoint.h: BeOS mutex functions * test/.cvsignore: Ignore files generates by the BeOS tests * test/Makefile.am: Add cairo-test-beos.* * test/cairo-test-beos.cpp: New.

test_fallback backend. 2005-12-16 Carl Worth * src/cairoint.h: Don't export cairo_image_surface_set_clip_region. * src/cairo-image-surface.c: (_cairo_image_surface_finish),

Now, all 5 operations have backend functions, and all use a consistent convention for argument naming and ordering. The old fill_path has been replaced with a new fill. The old show_glyphs function was recently renamed to old_show_glyphs and has not yet been ported to the new show_glyphs, (so all backends have a NULL show_glyphs function). In fact, of the 5 new backend functions, fill is the only one that has an implementation in any backend. As part of this cleanup a new cairo_stroke_style_t object is introduced to capture the many settings unique to the stroke operation, (line_width, line_cap, line_join, miter_limit, dash, num_dashes, and dash_offset). * src/cairo-meta-surface-private.h: * src/cairo-meta-surface.c: (_cairo_meta_surface_finish), (_cairo_meta_surface_fill), (_cairo_meta_surface_replay): * src/cairo-ps-surface.c: (_cairo_ps_surface_fill), (_ps_output_fill): * src/cairo-pdf-surface.c: (_cairo_pdf_surface_fill): Track changes in surface backend from fill_path to fill. * src/cairo-surface.c: (_fallback_paint), (_cairo_surface_paint), (_fallback_mask), (_cairo_surface_mask), (_fallback_stroke), (_cairo_surface_stroke), (_fallback_fill), (_cairo_surface_fill), (_fallback_show_glyphs), (_cairo_surface_show_glyphs): * src/cairo-gstate.c: (_cairo_gstate_init), (_cairo_gstate_paint), (_cairo_gstate_mask), (_cairo_gstate_stroke), (_cairo_gstate_fill), (_cairo_gstate_show_glyphs): Track the new canonical argument naming and ordering for the 5 drawing operations. * src/cairo-gstate-private.h: * src/cairo-gstate.c: (_cairo_gstate_init), (_cairo_gstate_init_copy), (_cairo_gstate_fini), (_cairo_gstate_set_line_width), (_cairo_gstate_get_line_width), (_cairo_gstate_set_line_cap), (_cairo_gstate_get_line_cap), (_cairo_gstate_set_line_join), (_cairo_gstate_get_line_join), (_cairo_gstate_set_dash), (_cairo_gstate_set_miter_limit), (_cairo_gstate_get_miter_limit), (_cairo_gstate_stroke), (_cairo_gstate_in_stroke), (_cairo_gstate_stroke_extents): * src/cairo-path-stroke.c: (_cairo_stroker_start_dash), (_cairo_stroker_step_dash), (_cairo_stroker_init), (_cairo_stroker_join), (_cairo_stroker_add_cap), (_compute_face), (_cairo_stroker_curve_to_dashed), (_cairo_path_fixed_stroke_to_traps): Move various stroke style settings into new cairo_stroke_style_t. * src/cairo-glitz-surface.c: * src/cairo-win32-surface.c: * src/cairo-xcb-surface.c: * src/cairo-xlib-surface.c: Drop NULL fill_path backend function which no longer exists. 2005-11-01 Carl Worth Reviewed by: keithp * src/cairoint.h: * src/cairo-atsui-font.c: (_cairo_atsui_font_old_show_glyphs): * src/cairo-glitz-surface.c: (_cairo_glitz_surface_old_show_glyphs): * src/cairo-image-surface.c: * src/cairo-meta-surface.c: (_cairo_meta_surface_old_show_glyphs), (_cairo_meta_surface_replay): * src/cairo-pdf-surface.c: (_cairo_pdf_surface_old_show_glyphs): * src/cairo-ps-surface.c: (_cairo_ps_surface_old_show_glyphs), (_ps_output_old_show_glyphs): * src/cairo-quartz-surface.c: * src/cairo-win32-surface.c: * src/cairo-xcb-surface.c: * src/cairo-xlib-surface.c: (_cairo_xlib_surface_old_show_glyphs8), (_cairo_xlib_surface_old_show_glyphs16), (_cairo_xlib_surface_old_show_glyphs32), (_cairo_xlib_surface_old_show_glyphs): Rename surface->backend->show_glyphs to surface->backend->old_show_glyphs. * src/cairoint.h: * src/cairo-gstate.c: (_cairo_gstate_show_glyphs): * src/cairo-surface.c: (_cairo_surface_old_show_glyphs_draw_func), (_fallback_show_glyphs), (_cairo_surface_show_glyphs), (_cairo_surface_old_show_glyphs): Move show_glyphs fallback from gstate to surface where it belongs. 2005-11-01 Keith Packard * src/cairo-surface.c: (_fallback_stroke), (_cairo_surface_stroke): Clean up argument order for _fallback_stroke to match other functions 2005-10-31 Carl Worth Originally 2005-10-28 Keith Packard : * src/cairo-gstate-private.h: Remove pen_regular field from the gstate. * src/cairoint.h: * src/cairo-gstate.c: (_cairo_gstate_init), (_cairo_gstate_init_copy), (_cairo_gstate_fini), (_cairo_gstate_stroke), (_cairo_gstate_in_stroke), (_cairo_gstate_stroke_extents): * src/cairo-path-stroke.c: (_cairo_stroker_start_dash), (_cairo_stroker_step_dash), (_cairo_stroker_init), (_cairo_stroker_fini), (_cairo_stroker_join), (_cairo_stroker_add_cap), (_compute_face), (_cairo_stroker_add_sub_edge), (_cairo_stroker_line_to_dashed), (_cairo_stroker_curve_to), (_cairo_stroker_curve_to_dashed), (_cairo_path_fixed_stroke_to_traps): * src/cairo-surface.c: (_fallback_stroke), (_cairo_surface_stroke): Move stroke fallback from gstate to surface where it belongs. * src/cairo-pen.c: (_cairo_pen_init): Eliminate dependence on cairo_gstate_t object. * src/cairo-meta-surface.c: Fix to include just cairo-clip-private.h rather than cairo-gstate.private.h. 2005-10-31 T Rowley * src/cairo-win32-font.c (_cairo_win32_scaled_font_init_glyph_path): Call _cairo_scaled_glyph_set_path(). 2005-10-28 Keith Packard * src/cairo-surface.c: (_fallback_paint): Use _cairo_pattern_get_extents in _fallback_paint to bound paint operators. 2005-10-28 Keith Packard * src/cairo-pattern.c: (_cairo_pattern_get_extents): * src/cairo-surface.c: (_fallback_mask): * src/cairoint.h: Bound mask fallback operation by transformed mask and source.

Xfake has been working quite well for a very long time now. font-size="0" in SVG does bad things: FIXED. 2005-08-22 Bertram Felgenhauer * src/cairoint.h, src/cairo-matrix.c (_cairo_matrix_compute_eigen_values): remove. 2005-08-22 Bertram Felgenhauer * src/cairo-arc.c (_arc_segments_needed): correct the calculation of the error bound. 2005-08-22 Bertram Felgenhauer * src/cairo-pen.c (_cairo_pen_vertices_needed): use new function. strip comment of derivation for major axis length. * src/cairo-matrix.c (_cairo_matrix_transformed_circle_major_axis): use _cairo_matrix_get_affine to retrieve matrix entries. * src/cairoint.h, src/cairo-matrix.c (_cairo_matrix_transformed_circle_major_axis): new function split out of cairo-pen.c. UTF8-ify the comment that explains the calculation. 2005-08-22 Bertram Felgenhauer * src/cairo-pen.c (_cairo_pen_vertices_needed): use correctly transposed version of the matrix and fix up the comments above to use row vector notation. 2005-08-22 Tor Lillqvist * configure.in: Calculate LT_CURRENT_MINUS_AGE (which forms part of the DLL name on Win32), and AC_SUBST it. * Makefile.am: Add target "zips" to create zip file based distribution for Win32. * src/Makefile.am: Produce a cairo.def file for distribution by preprocessing the relevant header files and grepping for declarations of functions that start with cairo_. Works for now, will have to modify later if necessary. Use the .def file when linking on Win32. 2005-08-22 Owen Taylor Support artificial bold fonts with FC_EMBOLDEN; patch from Jackey Yang and sunmoon1997. * configure.in: Check for FT_GlyphSlot_Embolden() * src/cairo-ft-font.c: Call FT_GlyphSlot_Embolden for fonts where FC_EMBOLDEN is set but that aren't bold.

These functions round nicely, and solve some inconsistencies in rendering between my PPC and x86 machines. Thanks to Owen Taylor for suggesting the fix. * test/gradient-alpha-ref.png: * test/linear-gradient-ref.png: * test/text-pattern-ref.png: The above change does affect linear gradients slightly, but it seems worth it.

(#2298) 2005-08-18 Owen Taylor * src/cairo-xlib-surface.c (_cairo_xlib_surface_show_glyphs): Fix offset passed in for source patterns. (#2333, Tim Rowley) * test/text-pattern.c: Fix font to Vera Sans rather than "Sans" 2005-08-18 Carl Worth * ROADMAP: Update the roadmap. Remove difficulty rating from completed tasks. Note that PostScript/PDF is (grudgingly) done as far as 1.0 is concerned, but there is more work to completing this that is slipped beyond 1.0. Note that the deadlock bug is fixed as of 0.9.2.

Rename the pattern creating helper function to match. * test/composite-integer-translate-over.c: (draw): * test/composite-integer-translate-source.c: (draw): Use new cairo_test_create_surface_from_png so that non-srcdir builds work. * test/mask.c: (set_image_pattern): * test/trap-clip.c: (set_image_pattern): Track change in cairo_test_create_pattern_from_png. 2005-07-18 Carl Worth * BUGS: Add note that Xlib caches need to be cleand up on close of display. 2005-07-15 Carl Worth * src/cairo-font.c: * src/cairo-surface.c: Remove cairo_private qualifier from .c files, (we only need it in the .h files). 2005-07-15 Vladimir Vukicevic * src/cairo-xlib-surface.c: (_cairo_xlib_surface_composite, _recategorize_composite_repeat): Use XCopyArea when possible, for optimization and bug workaround. * test/composite-integer-translate-{source,over,over-repeat}.c: Exercise XCopyArea, XRenderComposite, and XSetTile/XFillRectangle paths for _cairo_xlib_surface_composite 2005-07-15 Carl Worth * test/Makefile.am: Add new check-valgrind target for running the test suite under the influence of valgrind. * test/buffer-diff.c: (image_diff): Fix memory leak when reference image is not found. 2005-07-15 Carl Worth * test/mask.c: (set_gradient_pattern), (set_image_pattern), (draw): Fix a few memory leaks (missing cairo_pattern_destroy in 3 places). 2005-07-15 Carl Worth * src/cairo-gstate.c: (_cairo_gstate_mask): Fix memory leak, (missing _cairo_pattern_fini). 2005-07-15 Carl Worth * test/cairo-test.c (cairo_test_for_target): Remove errant line of code that was inadvertently committed recently. 2005-07-14 Carl Worth * test/surface-finish-twice.c: (draw): Fix leak of surface. 2005-07-14 Carl Worth * src/cairo-pdf-surface.c: (_cairo_pdf_surface_finish), (_cairo_pdf_document_finish): Call _cairo_array_fini on the several array objects to patch memory leaks. 2005-07-14 Carl Worth * src/cairo-xlib-surface.c: (_cairo_xlib_surface_composite), (_cairo_xlib_surface_composite_trapezoids), (_cairo_xlib_surface_show_glyphs): Eek. Yet _more_ fixups for _cairo_pattern_release_surface missed earlier. 2005-08-14 Stuart Parmenter * src/cairo-win32-surface.c: (_cairo_win32_surface_fill_rectangles): blue and green values were swapped in the DO_SOURCE case. 2005-07-14 Carl Worth * test/cairo-test.c: (cairo_test_create_png_pattern): Rewrite to use cairo_image_surface_create_from_png rather than custom read_png_argb32. In addition to being simpler, this eliminates the leak of the image data buffer. * test/trap-clip.c: (set_gradient_pattern), (set_image_pattern): Add calls to cairo_pattern_destroy to close two memory leaks. 2005-07-14 Carl Worth * src/cairo-pattern.c: (_cairo_pattern_acquire_surfaces): Fix up one more call to _cairo_pattern_release_surface missed in the previous commit. 2005-07-14 Carl Worth * src/cairoint.h: * src/cairo-pattern.c: (_cairo_pattern_release_surface): Fix to accept a cairo_pattern_t rather than a cairo_surface_t as the primary argument. * src/cairo-image-surface.c: (_cairo_image_surface_composite), (_cairo_image_surface_composite_trapezoids): Track change in _cairo_pattern_release_surface and also pass the appropriate pattern for each acquired surface. The previous backend mismatch was causing memory leaks. * src/cairo-xlib-surface.c: (_get_image_surface): Remove stale comment. * test/xlib-surface.c: (main): Add missing fclose to keep valgrind happy about memory leaks. 2005-07-14 Carl Worth * test/cairo-test.c: (cairo_test_expecting), (cairo_test_expect_failure), (cairo_test): Make the per-backend test results print XFAIL rather than FAIL for expected failures. 2005-07-14 Carl Worth * test/cairo-test.c: (cairo_test_real): Fix comment describing test result. It's not enough that all tested backends are successful. We also require that at least one backend is actually tested. 2005-07-14 Carl Worth * test/cairo-test.c: (cairo_test_for_target), (cairo_test_real): * test/cairo-test.h: Don't consider a test to fail if it can't create a surface at all (eg. no X server is available). Instead mark this backend as untested and only consider the overall test a success if all tested backend are successful. 2005-07-14 Carl Worth * src/cairo-ps-surface.c: (pattern_is_translucent): Add missing (putatively unreachable) return value. 2005-07-14 Carl Worth * src/cairo-image-surface.c: (_cairo_image_surface_set_clip_region): Remove the copying of the region. This was a workaround for a missing copy bug in libpixman that has since been fixed. So now it was just a memory leak. 2005-07-14 Carl Worth * src/cairo-png.c (read_png): Patch memory leak of png_info object. 2005-07-14 Carl Worth * test/.cvsignore: * test/Makefile.am: * test/create-for-png-ref.png: * test/create-for-png.c: * test/create-from-png.c: (draw): Rename create-for-png test to create-from-png to match the naming of the cairo_image_surface_create_from_png function. 2005-07-14 Carl Worth * test/cairo-test.c: (cleanup_xcb), (cleanup_xlib), (cairo_test_for_target), (cairo_test_real): Patch a few memory leaks. 2005-07-13 Kristian Høgsberg * src/cairo-meta-surface.c: (_cairo_meta_surface_replay): Use the _cairo_surface_*() functions when replaying. * src/cairo-ps-surface.c: Fold the "locate fallbacks" pass into the postscript output pass, and add a simple, first implementation of image fallbacks. 2005-07-13 Carl Worth * src/cairoint.h: * src/cairo-font.c: (_cairo_simple_font_face_create_font): Rename CAIRO_FONT_BACKEND_DEFAULT to the more accurate CAIRO_SCALED_FONT_BACKEND_DEFAULT. 2005-07-13 Carl Worth * src/cairo-ft-private.h: * src/cairo-ft-font.c: (_cairo_unscaled_font_is_ft), (_cairo_scaled_font_is_ft): New predicates to allow checking for cairo_ft derivates of generic font type. * src/cairo-ps-surface.c: (_cairo_ps_surface_get_font), (_cairo_ps_surface_show_glyphs), (_ps_output_show_glyphs): * src/cairo-pdf-surface.c: (_cairo_pdf_document_get_font), (_cairo_pdf_surface_show_glyphs): * src/cairo-font-subset.c: (_cairo_font_subset_create): Add explicit checks for cairo_ft derivatives of generic fonts rather than just blindly assuming that's what we get. 2005-07-12 Carl Worth * src/cairo-hash-private.h: * src/cairo-hash.c: (_cairo_hash_table_create): Remove destroy notifier. This simplifies the implementation a bit, and no anticipated use of cairo_hash_table_t in cairo needs the destroy notifier. Most uses will be hash-backed object create/destroy functions. (_cairo_hash_table_destroy): Document that it is now a fatal error to call _cairo_hash_table_destroy on a non-empty hash table. (_cairo_hash_table_insert): Document that it is now a fatal error to insert an entry with a key that matches an existing entry. (_cairo_hash_table_random_entry): Add predicate function so that the user can select a random entry satisying the given predicate. (_cairo_hash_table_remove): Change return type to void since failure is really not possible here. 2005-07-11 Carl Worth * ROADMAP: Add cache lock deadlock problem to roadmap for 0.5.2. Fix typo (cairo_ft_options_t -> cairo_font_options_t). Add note that glyph measurement performance needs to improve. * src/cairoint.h: Disable mutex locks, (making the caches non-thread-safe again, just like they were in the last snapshot and before). 2005-07-11 Carl Worth * ROADMAP: Note that the cairo_content_t work is done. Note progress on cairo_meta_surface_t, ARGB text, and group support. Add recent API change proposals (cairo_ft_options_t, cairo_xlib_surface_create needs to be screen aware, and cairo_xlib_surface_set_drawable). * src/cairo-arc.c (_arc_segments_needed): Note that this function is computing an incorrect result. 2005-07-08 Carl Worth * src/cairo.h: Give enum tags an underscore prefix to match the style of the struct tags.

This is slightly more painful to use, but lends itself to a more memory-efficient implementation. Add documentation. 2005-06-29 Carl Worth * src/cairo-hash-private.h: * src/cairo-hash.c: (_cairo_hash_table_create), (_cairo_hash_table_destroy_entry), (_cairo_hash_table_destroy), (_cairo_hash_table_lookup_internal), (_cairo_hash_table_resize), (_cairo_hash_table_lookup), (_cairo_hash_table_insert), (_cairo_hash_table_remove), (_cairo_hash_table_foreach): Rework the cache code as a hast table with a much simpler interface, (no object derviation is required to use it). * src/cairoint.h: Remove extraneous prototype for non-existent _cairo_cache_reference. 2005-06-28 Kristian Høgsberg * src/cairo-pattern.c (cairo_pattern_create_rgb) (cairo_pattern_create_rgba): New functions to create a cairo_pattern_t corresponding to a solid color and a translucent color respectively.

Add _cairo_cache_shrink_to which reduces cache memory usage to a specified level. Change global glyph and xlib glyphset caches behaviour to only shrink cache on unlock. This is done by telling the cache code to never shrink (max_memory == 0), and then manually shrinking using _cairo_cache_shrink_to from the unlock function. Fix Carl's variable renaming mixing (cache = cache). 2005-06-24 Owen Taylor * src/cairo-ft-font.c (_transform_glyph_bitmap): Add mostly useless (other than perhaps 90-degree rotation) code for transforming bitmap glyphs. 2005-06-25 Carl Worth From: J.

This allows the user to set a breakpoint on error and will allow us to augment error handling later as necessary. * src/cairo.c: (cairo_create), (cairo_reference), (cairo_destroy), (cairo_save), (cairo_restore), (cairo_set_operator), (cairo_set_source_rgb), (cairo_set_source_rgba), (cairo_set_source_surface), (cairo_set_source), (cairo_get_source), (cairo_set_tolerance), (cairo_set_fill_rule), (cairo_set_line_width), (cairo_set_line_cap), (cairo_set_line_join), (cairo_set_dash), (cairo_set_miter_limit), (cairo_translate), (cairo_scale), (cairo_rotate), (cairo_transform), (cairo_set_matrix), (cairo_identity_matrix), (cairo_user_to_device), (cairo_user_to_device_distance), (cairo_device_to_user), (cairo_device_to_user_distance), (cairo_new_path), (cairo_move_to), (cairo_line_to), (cairo_curve_to), (cairo_arc), (cairo_arc_negative), (cairo_rel_move_to), (cairo_rel_line_to), (cairo_rel_curve_to), (cairo_rectangle), (cairo_close_path), (cairo_paint), (cairo_paint_with_alpha), (cairo_mask), (cairo_mask_surface), (cairo_stroke_preserve), (cairo_fill_preserve), (cairo_copy_page), (cairo_show_page), (cairo_in_stroke), (cairo_in_fill), (cairo_stroke_extents), (cairo_fill_extents), (cairo_clip_preserve), (cairo_reset_clip), (cairo_select_font_face), (cairo_get_font_face), (cairo_font_extents), (cairo_set_font_face), (cairo_set_font_size), (cairo_set_font_matrix), (cairo_get_font_matrix), (cairo_text_extents), (cairo_glyph_extents), (cairo_show_text), (cairo_show_glyphs), (cairo_text_path), (cairo_glyph_path), (cairo_get_operator), (cairo_get_tolerance), (cairo_get_current_point), (cairo_get_fill_rule), (cairo_get_line_width), (cairo_get_line_cap), (cairo_get_line_join), (cairo_get_miter_limit), (cairo_get_matrix), (cairo_get_target), (cairo_copy_path), (cairo_copy_path_flat), (cairo_append_path), (cairo_status): Make all assignements to cr->status go through the new _cairo_error function. Remove CAIRO_CHECK_SANITY macro. 2005-06-15 Carl Worth * doc/public/cairo-sections.txt: Remove cairo-atsui section since cairo-atsui.h is currently empty. Add cairo_path_data_type_t and cairo_path_data_t. * test/.cvsignore: Add pdf-clip and pdf-clip.pdf. 2005-06-14 Kristian Høgsberg * src/cairo-gstate-private.h: * src/cairo-gstate.c: (_cairo_gstate_init), (_cairo_gstate_init_copy), (_cairo_gstate_fini), (_cairo_gstate_set_clip), (_composite_trap_region), (_cairo_gstate_fill), (_cairo_gstate_reset_clip), (_cairo_gstate_intersect_clip_path), (_cairo_clip_path_reference), (_cairo_clip_path_destroy), (_cairo_gstate_intersect_clip_region), (_cairo_gstate_intersect_clip_mask), (_cairo_gstate_clip): * src/cairo-pdf-surface.c: (_cairo_pdf_surface_create_for_document), (_cairo_pdf_path_move_to), (_cairo_pdf_path_line_to), (_cairo_pdf_path_close_path), (_cairo_pdf_surface_fill_path), (_cairo_pdf_surface_intersect_clip_path), (_cairo_pdf_document_add_page): * src/cairo-surface.c: (_cairo_surface_get_clip_mode), (_cairo_surface_fill_path), (_cairo_surface_reset_clip), (_cairo_surface_set_clip_path_recursive), (_cairo_surface_set_clip_path): * src/cairoint.h: Implement path clipping and refactor _cairo_gstate_clip() out in three different functions corresponding to the three different clipping modes. * src/cairo-glitz-surface.c: * src/cairo-ps-surface.c: * src/cairo-win32-surface.c: * src/cairo-xcb-surface.c: * src/cairo-xlib-surface.c: * src/cairo-image-surface.c: * src/cairo-quartz-surface.c: Add NULL pointers for intersect_clip_path. * test/Makefile.am: * test/pdf-clip.c: New test case to exercise PDF clipping code. 2005-06-14 Carl Worth * src/cairo-glitz-surface.c: (_cairo_glitz_surface_create_similar), (_cairo_glitz_surface_clone_similar), (_cairo_glitz_pattern_acquire_surface), (_cairo_glitz_surface_composite_trapezoids): * src/cairo-image-surface.c: (_cairo_image_surface_create_similar): * src/cairo-pdf-surface.c: (_cairo_pdf_surface_create_similar): * src/cairo-ps-surface.c: (_cairo_ps_surface_create_similar): * src/cairo-quartz-surface.c: (_cairo_quartz_surface_create_similar): * src/cairo-surface.c: (_cairo_surface_create_similar_scratch), (_cairo_surface_create_similar_solid): * src/cairo-win32-surface.c: (_cairo_win32_surface_create_similar), (_cairo_win32_surface_get_subimage): * src/cairo-xcb-surface.c: (_cairo_xcb_surface_create_similar), (_cairo_xcb_surface_clone_similar): * src/cairo-xlib-surface.c: (_cairo_xlib_surface_create_similar), (_cairo_xlib_surface_clone_similar): * src/cairoint.h: Remove Boolean 'drawable' parameter from the create_similar surface backend function since nothing anywhere is actually using this parameter. 2005-06-14 T Rowley * src/cairo-win32-font.c: Correct extents for text with a general tranform. 2005-06-14 Carl Worth * src/cairo.h: Remove comment suggesting ambiguity of whether cairo_get_target references the surface, (we decided as part of the API shakeup that cairo functions returning pointers to internal objects do not automatically take a reference). 2005-06-13 Carl Worth * src/cairoint.h: * src/cairo-pattern.c: (_cairo_pattern_create_in_error): Add new _cairo_pattern_create_in_error. * src/cairo.c: (cairo_get_source): Propagate error values from cr->status to pattern->status. 2005-06-13 Carl Worth * src/cairo.c (_cairo_set_source_solid), (cairo_set_source_surface), (cairo_mask_surface): No longer need to check for NULL after creating a pattern. * src/cairo.c (cairo_set_source), (cairo_mask): Propagate status errors from pattern->status to cr->status. Originally 2005-05-08 Owen Taylor : * src/cairo-pattern.c src/cairoint.h: If allocation of pattern objects fails, return special static nil pattern objects. * src/cairo-pattern.c: If adding a color stop fails to allocate memory, set pattern->status. (And fix a memory leak.) Make public functions return when pattern->status is set, (and no longer return a cairo_status_t). * src/cairo-pattern.c src/cairo.h doc/public/cairo-sections.txt: Add cairo_pattern_status() * src/cairo-gstate.c: Check the status of gstate->source and of mask patterns passed in. 2005-06-13 Carl Worth Originally 2005-05-08 Owen Taylor : * src/cairo.c (cairo_create): If cairo_create() fails, return a special static object, cairo_nil. * src/cairo.c (cairo_reference): Don't return early if cr->status is set. cr->status should not affect reference counting. * src/cairo.c: (cairo_reference), (cairo_destroy): Ignore any magic object with a reference count of -1. 2005-06-13 Carl Worth Originally 2005-06-02 Carl Worth : * src/cairo.h: Add a status field to cairo_path_t. * src/cairo.c: (cairo_copy_path), (cairo_copy_path_flat): Add documentation for the new approach for handling errors in these functions---always returning a valid pointer with at least a status. (cairo_append_path): Propagate path status errors to the context. Add note to documentation on initializing path->status. * src/cairo-path-data-private.h: Add missing cairo_private qualifier to a couple functions. * src/cairo-path-data.c: (_cairo_path_data_create_real): Track new status field in cairo_path_t.

(_cairo_path_data_create_in_error): New function to create a placeholder cairo_path_t just to propagate a cairo_status_t error. 2005-06-11 Carl Worth * src/cairoint.h: * src/cairo-gstate.c: (_cairo_gstate_init, _cairo_gstate_init_copy, _cairo_gstate_fini): Make these functions static, which allows slightly less awkward error handling within them. 2005-06-10 Carl Worth * src/cairoint.h: Provide font-backend-specific macros for FONT_FAMILY_DEFAULT. Change CAIRO_FT_FONT_FAMILY_DEFAULT from "serif" to "" to allow the actual default to come from the system/user configuration. 2005-06-10 Carl Worth * src/cairo.h: Pull the enum out from inside cairo_path_data_t and give it a name of cairo_path_data_type_t. This allows C++ programs to see the enum values. It also allows variables to be declared of this type for manually constructing a cairo_path_t. 2005-06-10 Carl Worth * ROADMAP: Add 'consistent error handling' to 1.0 roadmap. (This isn't new, we just forgot to list it here before). * TODO: Big cleanup to remove finished items. Also, split the file up to separate TODO items that affect the API from items that do not. 2005-06-10 Carl Worth Originally: 2005-06-09 Carl Worth * src/cairo-pdf-surface.c: (_cairo_pdf_surface_show_page): * src/cairo-xcb-surface.c: (_cairo_xcb_surface_acquire_source_image), (_cairo_xcb_surface_acquire_dest_image): * src/cairo-xlib-surface.c: (_cairo_xlib_surface_acquire_source_image), (_cairo_xlib_surface_acquire_dest_image): Rework occurrences of 'if (status == CAIRO_STATUS_SUCCESS)' to use 'if (status)' instead where trivial. 2005-06-10 Carl Worth * src/cairoint.h: * src/cairo-font.c: * src/cairo-ft-font.c: * src/cairo-glitz-surface.c: * src/cairo-gstate.c: * src/cairo-image-surface.c: * src/cairo-pattern.c: * src/cairo-pdf-surface.c: * src/cairo-png.c: * src/cairo-surface.c: * src/cairo-win32-font.c: * src/cairo-win32-surface.c: * src/cairo-xcb-surface.c: * src/cairo-xlib-surface.c: Remove STATUS_OK macro which was not being used universally. 2005-06-09 Carl Worth * src/cairo.h: Remove trailing comma from enum values which gcc 4.0 does not want to see (Luis Villa). Closes bug #3502. 2005-06-09 Owen Taylor * test/Makefile.am (INCLUDES): Add -I$(top_builddir)/src for cairo-features.h (Tomasz Cholewo) 2005-06-07 Keith Packard * src/cairo-pdf-surface.c: (_cairo_pdf_surface_show_glyphs): Font matrix was output incorrectly; the implicit mirror-in-y transformation was not computed correctly, missing a negation of the 'xy' component. 2005-06-02 Kristian Høgsberg * src/cairo-gstate.c (_cairo_gstate_clip): When clipping, update the clip surface to a new surface the size of the intersection of the old clip surface and the extents of the new clip path. 2005-06-03 Carl Worth * src/cairo-font.c: (cairo_font_face_reference), (cairo_font_face_destroy), (_cairo_simple_font_face_destroy), (_cairo_unscaled_font_reference), (_cairo_unscaled_font_destroy), (cairo_scaled_font_reference), (cairo_scaled_font_destroy): * src/cairo-ft-font.c: (_ft_font_cache_destroy_cache), (_cairo_ft_unscaled_font_destroy), (_ft_font_face_destroy): * src/cairo-glitz-surface.c: (_cairo_glitz_area_destroy): * src/cairo-path-data.c: (cairo_path_destroy): * src/cairo-pdf-surface.c: (cairo_pdf_font_destroy), (cairo_pdf_ft_font_destroy): * src/cairo-win32-font.c: (_cairo_win32_scaled_font_destroy): Allow NULL as a valid value for several objects. That is, calling reference or destroy on these objects will simply do nothing, successfully. * src/cairo-atsui-font.c: (_cairo_atsui_font_destroy_font): Remove extra whitespace. 2005-06-03 Carl Worth * src/cairoint.h: * src/cairo-cache.c: (_cairo_cache_init), (_cairo_cache_destroy): Remove unused cache->refcount and _cairo_cache_reference(). * src/cairo-cache.c: (_cairo_cache_destroy): Remove gratuitous nesting as recommended in CODING_STYLE. 2005-06-03 Carl Worth * src/cairoint.h: * src/cairo-array.c: (_cairo_user_data_array_fini): * src/cairo-font.c: (cairo_font_face_destroy): * src/cairo-surface.c: (cairo_surface_destroy): Fix name of _cairo_user_data_array_destroy to be _cairo_user_data_array_fini. 2005-06-03 Carl Worth * src/cairo-glitz-surface.c: (_cairo_glitz_glyph_cache_create_entry), (_cairo_glitz_glyph_cache_destroy_entry), (_cairo_glitz_glyph_cache_destroy_cache), (_cairo_glitz_surface_show_glyphs): Rename functions to match the naming scheme used by cairo-cache.c and all other users of it. Though it's quite likely that glitz had this right and now everything could be changed to match it instead. I'll save that for some day when we're cleaning up the cache code. 2005-06-03 Carl Worth * CODING_STYLE: Fix spelling errors. 2005-06-03 Carl Worth * CODING_STYLE: Fix Freudian unwrapped line in paragraph describing why long lines should be wrapped. 2005-06-03 Carl Worth * CODING_STYLE: Add CODING_STYLE document to standardize on some style issues. * src/cairo-atsui-font.c: * src/cairo-cache.c: * src/cairo-ft-font.c: * src/cairo-glitz-surface.c: * src/cairo-gstate.c: * src/cairo-matrix.c: * src/cairo-pattern.c: * src/cairo-pdf-surface.c: * src/cairo-spline.c: * src/cairo-wideint.c: * src/cairo-win32-font.c: * src/cairo-xlib-surface.c: Standardize brace handling around all else clauses according to new CODING_STYLE guidelines. 2005-06-03 Kristian Høgsberg Patch from Tomasz Cholewo : * src/cairo-pdf-surface.c: (cairo_pdf_ft_font_write_head_table), (cairo_pdf_ft_font_generate): Store the index of the checksum instead of a pointer to the location. 2005-06-03 Carl Worth * src/cairoint.h: * src/cairo-gstate.c: * src/cairo.c: (_cairo_set_source_solid), (cairo_set_source_rgb), (cairo_set_source_rgba): Move internal convenience up from _cairo_gstate_set_source_solid to _cairo_set_source_solid so that all set_source functions flow through cairo_set_source. 2005-06-01 Carl Worth * src/cairo-gstate.c: (_cairo_gstate_init): Remove obsolete _cairo_gstate_set_target_surface, folding its contents into _cairo_gstate_init, most of which disappears due to constant folding. Ensure that gstate->next is initialized even if _cairo_pattern_create_solid fails. * src/cairo-xcb-surface.c: Remove unused _cairo_xcb_surface_set_clip_region. 2005-06-01 Carl Worth * src/cairoint.h: * src/cairo-font.c: * src/cairo-ft-font.c: * src/cairo-glitz-surface.c: * src/cairo-gstate.c: * src/cairo-image-surface.c: * src/cairo-pattern.c: * src/cairo-pdf-surface.c: * src/cairo-png.c: * src/cairo-surface.c: * src/cairo-win32-font.c: * src/cairo-win32-surface.c: * src/cairo-xcb-surface.c: * src/cairo-xlib-surface.c: Rename CAIRO_OK to STATUS_OK. No intended changes in functionality. 2005-06-01 Carl Worth * src/cairo-gstate-private.h: * src/cairo-gstate.c: Rename gstate->surface to gstate->target. No intended changes in functionality. 2005-06-01 Carl Worth * src/cairo-gstate-private.h: * src/cairo-gstate.c: (_cairo_gstate_init): Remove unused fields from cairo_gstate_t, (font_family, font_slant, font_weight). Reorder fields to match between declaration and initialization and to put the most problematic fields (surface and source) at the end. No intended changes in functionality. 2005-06-01 Carl Worth * test/Makefile.am (XFAIL_TESTS): Add self-intersecting to the list of expected failures. 2005-06-01 Carl Worth * test/.cvsignore: * test/Makefile.am: * test/self-intersecting-ref.png: * test/self-intersecting.c: (draw), (main): Add self-intersecting test which demonstrates the long-standing bug with stroking self-intersecting paths. 2005-06-01 Carl Worth * src/cairo-gstate.c (_cairo_gstate_get_clip_extents): Fix bug in converting box to rectangle that left clip_rect.height uninitialized, (leading to unpredictable, intermittent test failures). 2005-05-31 Carl Worth * src/cairo.h: * src/cairo.c: (cairo_status_to_string), (cairo_status_string): Add new function cairo_status_to_string an reimplement cairo_status_string in terms of the new function. 2005-05-27 Olivier Andrieu * src/cairo-path-data.c (_cpdc_curve_to_flatten), (_cpdp_curve_to_flatten) : Fix memory leak 2005-05-26 Keith Packard reviewed by: krh, otaylor, cworth Replace nesting-only surface clipping with gstate contained serial-number tracked clipping sets that are loaded into the surface on demand just before each rendering operation. This permits multiple cairo_t contexts to reference a surface without regard to ordering of operations among the contexts. Also in this patch is a change to the xlib surface that creates two separate Pictures, one for source and one for destination operands which separates the source clipping from destination clipping. Cairo now specifies that sources are never clipped by any clipping applied to them as destinations. * src/cairoint.h: * src/cairo-gstate-private.h: Move cairo_clip_t (renamed from cairo_clip_rec_t) from cairoint.h to cairo-gstate-private.h. Eliminate stack of clip state from surfaces. Add new surface clipping API. * src/cairo-gstate.c: (_cairo_gstate_init), (_cairo_gstate_init_copy), (_cairo_gstate_fini), (_cairo_gstate_has_surface_clip), (_cairo_gstate_set_clip), (_cairo_gstate_get_clip_extents), (_cairo_gstate_set_target_surface), (_cairo_gstate_paint), (_cairo_gstate_combine_clip_surface), (_cairo_gstate_intersect_clip), (_get_mask_extents), (_cairo_gstate_mask), (_cairo_gstate_stroke), (_clip_and_compute_extents_arbitrary), (_composite_trap_region), (_cairo_gstate_fill), (_cairo_gstate_reset_clip), (_cairo_gstate_clip), (_cairo_gstate_show_glyphs): Manage clip objects entirely within the gstate, loading the whole thing into the surface just before drawing. * src/cairo-pattern.c: (_cairo_pattern_acquire_surface_for_gradient), (_cairo_pattern_acquire_surface_for_solid), (_cairo_pattern_acquire_surface_for_surface), (_cairo_pattern_acquire_surface), (_cairo_pattern_release_surface): Source surfaces need not have clipping modified as the surface interface now specifies that source surfaces are always unclipped. * src/cairo-surface.c: (_cairo_surface_init), (cairo_surface_finish), (_cairo_surface_clone_similar), (_cairo_surface_get_current_clip_serial), (_cairo_surface_allocate_clip_serial), (_cairo_surface_reset_clip), (_cairo_surface_can_clip_region), (_cairo_surface_set_clip_region), (_cairo_surface_can_clip_path), (_cairo_surface_clip_path), (_cairo_surface_get_extents): Eliminate nested clipping contexts, leaving clip management entirely to the gstate. Create new clip API for the gstate which uses per-surface serial numbers to match gstate clipping against current surface clipping values. Surfaces no longer track clipping regions at all, so the old _cairo_surface_get_clip_extents has been replaced with _cairo_surface_get_extents. For PDF/PS surfaces, this function is expected to return a rectangle covering the entire fixed point coordinate space to leave rendering unclipped by the surface. * src/cairo-xcb-surface.c: Region clipping capability is now signalled by a non-NULL function pointer in set_clip_region. * src/cairo-xlib-surface.c: (_cairo_xlib_surface_finish), (_cairo_xlib_surface_ensure_src_picture), (_cairo_xlib_surface_ensure_dst_picture), (_cairo_xlib_surface_set_matrix), (_cairo_xlib_surface_set_filter), (_cairo_xlib_surface_set_repeat), (_cairo_xlib_surface_set_attributes), (_cairo_xlib_surface_composite), (_cairo_xlib_surface_fill_rectangles), (_cairo_xlib_surface_composite_trapezoids), (_cairo_xlib_surface_set_clip_region), (_cairo_xlib_surface_create_internal), (_cairo_xlib_surface_show_glyphs32), (_cairo_xlib_surface_show_glyphs16), (_cairo_xlib_surface_show_glyphs8), (_cairo_xlib_surface_show_glyphs): Each surface now contains two Pictures, one for source and one for destination operands so that source operands are never clipped by destination clipping. * src/cairo.h: * src/cairo.c: (cairo_status_string): CAIRO_STATUS_BAD_NESTING removed * test/Makefile.am: * test/self-copy.c: (main): self-copy now passes (Xlib only, until libpixman changes land) 2005-05-26 Olivier Andrieu * src/cairo.c: trivial doc fixes. 2005-05-24 Carl Worth * gtk-doc.make: Re-synch with latest from gtk-doc CVS tree. * doc/public/Makefile.am (MKTMPL_OPTIONS): Add --only-section-tmpl option so that changes to inline documentation does not lead to churn in the .sgml template files. * doc/public/tmpl/cairo-font.sgml: * doc/public/tmpl/cairo-ft.sgml: * doc/public/tmpl/cairo-glitz.sgml: * doc/public/tmpl/cairo-matrix.sgml: * doc/public/tmpl/cairo-pattern.sgml: * doc/public/tmpl/cairo-pdf.sgml: * doc/public/tmpl/cairo-png.sgml: * doc/public/tmpl/cairo-ps.sgml: * doc/public/tmpl/cairo-quartz.sgml: * doc/public/tmpl/cairo-surface.sgml: * doc/public/tmpl/cairo-xcb.sgml: * doc/public/tmpl/cairo-xlib.sgml: * doc/public/tmpl/cairo.sgml: Commit new templates now that gtk-doc has ripped all the inline portions out. * doc/public/tmpl/cairo-win32.sgml: * doc/public/tmpl/cairo-xcb-xrender.sgml: * doc/public/tmpl/cairo-xlib-xrender.sgml: New template files added for new sections. * doc/public/cairo-sections.txt: Update to match current API. * src/cairo-xcb.h: Make parameter names match those in the .c file and its documentation. 2005-05-22 Carl Worth * src/cairo.c (cairo_create): Protect less-than and greater-than symbols in documentation string. * TODO: Not that a patch has been submitted for consistent error handling. * src/cairo.c: Fix documentation string for cairo_create so that it might actualyl appear in the manual. 2005-05-18 Carl Worth * configure.in: Add -head to CAIRO_VERSION after tagging with SNAPSHOT_0_5_0. 2005-05-17 Carl Worth * PORTING_GUIDE: Added porting guide to help with transition to cairo 0.5 API. * NEWS: Added notes for snapshot 0.5.0 * configure.in: Increment CAIRO_VERSION to 0.5.0 2005-05-17 Carl Worth * src/cairo-xcb-surface.c: (_get_image_surface), (_cairo_xcb_surface_create_internal): Bring up to date with Keith's latest improvements to cairo-xlib-surface.c: Add some comments about how and why masks are computed. Generalize overflow detection in mask computation. Expand on pixman format conversion comment. Fix the broken visual->format case. 2005-05-17 Carl Worth Two fixes from Kristian Høgsberg: * src/cairo-output-stream.c: (_cairo_output_stream_create), (_cairo_output_stream_destroy), (_cairo_output_stream_create_for_file): Fix to close the file if we opened it. * src/cairo-pdf-surface.c: (_cairo_pdf_document_finish): Grab the status from out of the stream _before_ we destroy the stream. 2005-05-17 Keith Packard * src/cairo-xlib-surface.c: (_get_image_surface): Add some comments about how and why masks are computed.

Add width, height to constructors and eliminate any synchronous size queries from the implementation. * test/cairo-test.c: (create_xlib_surface): * test/xlib-surface.c: (do_test): Update to match new cairo_xlib_surface_t create functions. 2005-05-17 Carl Worth * src/cairoint.h: * src/cairo-output-stream.c: Remove destroy_closure from cairo_output_stream_t interface. * src/cairo-pdf.h: * src/cairo-pdf-surface.c: Remove destroy_closure argument from cairo_pdf_surface_create_for_stream. Rename width,height to width_in_points, height_in_points for better clarity. * src/cairo-ps.h: * src/cairo-ps-surface.c: Brush a bunch of dust off of the PS backend and bring it up to date with the latest API conventions from the PDF backend. These include: accepting a filename rather than a FILE in the primary constructor, providing a stream-based interface for more flexibility, and accepting a surface size in device-space units (points) rather than inches. * test/pdf-surface.c: (main): Make it a little more clear that the width and height being passed around are in units of points. * test/ps-surface.c: (main): Update to the latest cairo-ps.h changes as described above.

This scale value is used only when computing gradient values before the defined range, in which case stop 0 is used for both ends of the interpolation, making the value of 'scale' not actually matter, except that valgrind notices we're using an undefined value. 2005-05-16 Carl Worth * test/.cvsignore: * test/Makefile.am: Remove quarter-over test name accidentally added to Makefile. 2005-05-16 Kristian Høgsberg * src/cairo-pdf-surface.c (cairo_pdf_surface_create): * src/cairo-output-stream.c (_cairo_output_stream_create_for_file): Take a filename instead of a FILE pointer. 2005-05-14 Carl Worth * src/cairo-xcb.h: * src/cairo-xcb-surface.c: (_cairo_xcb_surface_create_similar), (_cairo_xcb_surface_finish), (_cairo_xcb_surface_get_size), (_bits_per_pixel), (_bytes_per_line), (_get_image_surface), (_draw_image_surface), (_cairo_xcb_surface_get_extents), (_cairo_surface_is_xcb), (_cairo_xcb_surface_create_internal), (cairo_xcb_surface_create_for_pixmap), (cairo_xcb_surface_create_for_pixmap_with_visual), (cairo_xcb_surface_create_for_window_with_visual), (cairo_xcb_surface_set_size): Brush the dust off the XCB backend and get it compiling and working again. This patch makes the XCB surface API match that of the Xlib surface API as of yesterday. But, it's already stale as the Xlib API changed again. So we'll need one more revision of the XCB backend before the next snapshot. * test/.cvsignore: * test/Makefile.am: * test/cairo-test.c: (create_xcb_surface), (cleanup_xcb): * test/cairo-test.h: Add support for testing of the xcb backend as well. 2005-05-14 Carl Worth * test/cairo-test.c: (cairo_test_real): * test/pdf-surface.c: (main): * test/xlib-surface.c: (do_test), (main): Cleanup output a bit, move verbose messages to test-specific log file. 2005-05-14 Carl Worth * src/cairo-xlib-surface.c: (cairo_xlib_surface_create_with_visual): Fix the last commit so it actually compiles now. 2005-05-14 Carl Worth * src/cairo-xlib-surface.c: (cairo_test_xlib_disable_render), (cairo_xlib_surface_create_with_visual) * test/.cvsignore: Fix a few documentation typos in the recent xlib surface rework. 2005-05-14 Carl Worth * src/cairo-atsui.h: * src/cairo-ft.h: * src/cairo-glitz.h: * src/cairo-pdf.h: * src/cairo-ps.h: * src/cairo-quartz.h: * src/cairo-win32.h: * src/cairo-xcb.h: * src/cairo-xlib.h: Add an #error if cairo-foo.h is included when cairo was compiled without support for the foo backend. 2005-05-14 Carl Worth * test/pdf-surface.c (main): Update for change in cairo_pdf_surface_create which no longer accepts DPI values. 2005-05-13 Owen Taylor * src/cairo-xlib-surface.c src/cairo-xlib.h doc/public/cairo-sections.txt: Drop the _for_pixmap() and _for_window() out of the create functions and use some lazy cleverness to sniff the information out as needed. * src/cairo-xlib-surface.c src/cairo-xlib-test.h Makefile.am: add cairo_test_xlib_disable_render() to turn off RENDER for tests. * test/xlib-surface.c: Test various different types of Xlib surface creation. * src/cairo-xlib.h: Remove left-over include of Xrender.h. 2005-05-13 Kristian Høgsberg * src/cairo-pdf-surface.c (_cairo_pdf_document_open_stream): Make this a varg function and use the new _cairo_output_stream_vprintf() function to format extra dict contents. * src/cairo-output-stream.c (_cairo_output_stream_vprintf): Reimplement the printf logic so we can special case formatting of doubles to be locale independent and trim trailing zeros. * src/cairo-pdf-surface.c: Rename cairo_pdf_surface_create_for_callback() to cairo_pdf_surface_create_for_stream(), and change PDF constructors to take width and height as points and move PPI setting to cairo_pdf_surface_set_ppi() 2005-05-13 Owen Taylor * src/cairo-xlib-surface.c (_cairo_xlib_surface_create_internal): Fix misplaced goto. 2005-05-12 Carl Worth * src/cairoint.h: * src/cairo-image-surface.c: (_cairo_image_surface_create_with_masks): Fix image->data to be unsigned * src/cairo-glitz-surface.c: (_cairo_glitz_surface_get_image): * src/cairo-image-surface.c: (_cairo_image_surface_create_for_pixman_image), * src/cairo-xlib-surface.c: (_get_image_surface), (_draw_image_surface), (_xlib_glyphset_cache_create_entry): Track change in signedness of data member/parameter. 2005-05-12 Carl Worth Update xcb backend to compile after recent API changes: * src/cairo-xcb-surface.c: (_cairo_xcb_surface_finish): Fix missing return value.

The motivation for this is that not all backends want a surface for the source operand, and by passing the pattern down, backends can choose to convert it to a surface if they need that. The patch removes the create_surface function pointer from the surface vtable and moves much of that code into a couple of helper functions. The composite, compsite_trapezoids, and show_glyphs backend functions are updated to take a cairo_pattern_t instead of a surface as the source. * src/cairo_font.c: (_cairo_font_show_glyphs): * src/cairo_gstate.c: (_cairo_gstate_create_pattern), (_cairo_gstate_clip_and_composite_trapezoids), (_cairo_gstate_clip), (_cairo_gstate_show_surface), (_cairo_gstate_show_glyphs): Change these functions to not create a surface for the pattern and just pass the pattern down to the backend functions. * src/cairo_gstate.c: (translate_traps): New function to translate a set of trapezoids. * src/cairo_pattern.c: (_cairo_pattern_init), (_cairo_pattern_init_copy), (_cairo_pattern_prepare_surface), (_cairo_pattern_restore_surface): Break out the code to adjust and restore surface transformation and repeat settings into _cairo_pattern_prepare_surface and _cairo_pattern_restore_surface. * src/cairo_pattern.c: (_cairo_pattern_fini), (_cairo_pattern_init_for_surface), (cairo_pattern_create_for_surface): Split cairo_pattern_create_for_surface into an init function and a create function. * src/cairo_pattern.c: (_cairo_pattern_get_image), (_cairo_pattern_get_surface): Utility functions to create a surface from a pattern. * src/cairo_ft_font.c: * src/cairo_image_surface.c: * src/cairo_pdf_surface.c: * src/cairo_png_surface.c: * src/cairo_ps_surface.c: * src/cairo_xlib_surface.c: * src/cairo_glitz_surface.c: Update these backends to work with the new pattern API.

Many thanks to Sasha V. . * configure.in: We do three things here: Make the pkg-config check for xrender conditional, set XLIB_BACKEND_DEFINE to either CAIRO_HAS_XLIB_BACKEND or CAIRO_HAS_NO_XLIB_BACKEND to be substituted into cairo-config.h, and set an AM_CONDITIONAL for HAVE_XLIB_BACKEND to enable conditional compilation of cairo_xlib_surface.c. Perhaps that could be simplified a tad, but it's what we have working now. Also split up various PKG_CHECK_MODULES into separate checks. * src/cairo_gstate.c: Remove errant reference to cairo_gstate_set_drawable. * src/cairo.h: Move xlib-specific calls in from old cairo-xlib.h, now guarded in #ifdef CAIRO_HAS_XLIB_BACKEND. * src/Makefile.am (libcairo_xlib_sources): Make compilation of cairo_xlib_surface.c conditional.

Fix comments regarding freetype version checking. 2003-11-18 James Henstridge * cairo.pc.in (Cflags): add FREETYPE_CFLAGS/LIBS to Libs/Cflags rather than requiring "freetype2", which doesn't exist in anything but the most recent version of freetype. * configure.in (FREETYPE_LIBS): add freetype cflags/libs substitutions. 2003-11-18 Carl Worth * src/cairo.h: Fix build for new freetype header include mechanism, (thanks to Christof Petig ) 2003-11-17 Carl Worth * Remove infinite looping when stroking with a line width at or close to 0.0. Thanks to Rob Buis and Noah Levitt for providing in-the-wild examples of SVG files with stroke-width:0 that demonstrated the problem, (cowboy.svg and albania.svg). * src/cairo_pen.c (_cairo_pen_stroke_spline): Do nothing if the pen is a degenerate, single point. This happens when the line width is a very small, non-zero value. * src/cairo_gstate.c (_cairo_gstate_stroke): Do nothing when asked to stroke a path with a line_width of 0.0. Previously, this would lead to an infinite loop. * src/cairo.c (cairo_set_line_width): Force negative line width to 0.0. * TODO: Updated TODO list. 2003-11-10 Carl Worth * configure.in: Fix typo (thanks to John Ellson ) * TODO: Add TODO items for intersection problem, programmatic patterns, missing text functions. 2003-11-06 Carl Worth * configure.in (CAIRO_VERSION): Bumped version to 0.1.12 for new cairo_in_stroke and cairo_in_fill functions. * src/cairo.h: * src/cairo.c (cairo_in_stroke): (cairo_in_fill): Added new cairo_in_stroke and cairo_in_fill. * src/cairo_traps.c (_cairo_trap_contains): (_cairo_traps_contain): * src/cairo_gstate.c (_cairo_gstate_in_stroke): (_cairo_gstate_in_fill): New functions to support for cairo_in_stroke and cairo_in_fill. Many thanks to Thomas Hunger for the initial implementation which demonstrated how easy this would be and pushed me to go and write it already. * src/cairo_gstate.c (_cairo_gstate_clip_and_composite_trapezoids): * src/cairo_traps.c (_line_segs_intersect_ceil): * src/cairo_path.c (_cairo_path_move_to): (_cairo_path_line_to): (_cairo_path_curve_to): Fixed to use _cairo_fixed_from_double instead of XDoubleToFixed. 2003-11-06 Carl Worth * src/cairo.c (cairo_current_font): Move declaration to beginning of function to avoid requiring a C99-compatible compiler. * src/cairo.h: Add comment pondering memory management semantics of cairo_current_target_surface. * src/cairo_pen.c (_cairo_pen_fini): NULL out pen->vertices after free. * src/cairo_image_surface.c (_cairo_image_abstract_surface_destroy): NULL out durface->data after free. 2003-11-04 Carl Worth * src/cairo_gstate.c (_cairo_gstate_set_target_surface): Enable cairo_set_target_surface (cr, NULL) to work. This can be useful to force the current target surface to be finalized. * configure.in: * cairo.pc.in (Requires): Add explicit fontconfig and freetype2 dependencies that were implicitly dropped along with Xft. 2003-11-04 Carl Worth * TODO: Note that cairo_show_page, cairo_copy_page, PostScript backend, "real" text API, and text support for the image backend have now all been implemented. 2003-11-04 Carl Worth * configure.in: * cairo.pc.in (Requires): cairo doesn't depend on Xft after the recent text work. 2003-11-03 Carl Worth * configure.in (CAIRO_VERSION): Bump version to 0.1.11 for new cairo_copy_page. * src/cairo_ps_surface.c (cairo_ps_surface_create): Now print header at time of surface_create rather than in show_page. (_cairo_ps_surface_destroy): Print document footer at time of surface_destroy rather than in show_page. (_cairo_ps_surface_erase): New function for sharing. (_cairo_ps_surface_copy_page): Now keep proper page count. (_cairo_ps_surface_show_page): Real work is now done in copy_page. show_page is only distinct in that it erases the surface afterwards. * src/cairo.h: * src/cairo.c (cairo_copy_page): * src/cairo_gstate.c (_cairo_gstate_copy_page): * src/cairo_surface.c (_cairo_surface_copy_page): * src/cairo_image_surface.c (_cairo_image_surface_copy_page): * src/cairo_xlib_surface.c (_cairo_xlib_surface_copy_page): Add support for new cairo_copy_page function. 2003-11-03 Carl Worth * src/cairo_ps_surface.c (cairo_set_target_ps): Add missing check for out of memory. * src/cairo_image_surface.c (_cairo_image_surface_create_with_masks): (_cairo_image_surface_create_with_masks): (cairo_image_surface_create): (cairo_image_surface_create): (cairo_image_surface_create_for_data): (cairo_image_surface_create_for_data): Add several missing checks for out of memory. 2003-11-03 Carl Worth * src/cairo.h: Added __external_linkage to a few functions that were missing it. 2003-11-01 Carl Worth * src/cairo_ps_surface.c (_cairo_ps_surface_show_page): Fix misplacement of PS origin, (was translating vertically by width instead of height). * configure.in (CAIRO_VERSION): Bumped version to 0.1.10 for new functions cairo_set_target_ps, cairo_ps_surface_create, and cairo_show_page. * src/cairo_ps_surface.c: New file with preliminary support for drawing to a PostScript file. Most of the ps_surface backend functions are just tiny wrappers, deferring to image_surface functions to do the real work. Then, in show_page, the image is compressed and spit out into the file. Crude and effective. * src/cairo.c (cairo_show_page): * src/cairo_gstate.c (_cairo_gstate_show_page): * src/cairo_image_surface (_cairo_image_surface_show_page): * src/cairo_xlib_surface.c (_cairo_xlib_surface_show_page): * src/cairo_surface.c (_cairo_surface_show_page): Implement new support for cairo_show_page -- just a stub in the non-PS surfaces. * src/cairo_image_surface.c (_cairo_image_surface_set_filter): Export this function for internal use. * src/cairo.h: Added cairo_set_target_ps, cairo_ps_surface_create, and cairo_show_page. Noted plans for new cairo_surface_clip_begin, perhaps moving some cairo_surface functions to cairo_set_pattern, and possibly renaming cairo_matrix_t to cairo_transform_t. * src/Makefile.am (libcairo_la_SOURCES): Added cairo_ps_surface.c. 2003-10-31 Carl Worth * src/cairo_gstate.c (_cairo_gstate_arc): (_cairo_gstate_arc_negative): Do nothing when radius <= 0.0, (which is much better than the current infinite loop). 2003-10-31 Carl Worth * Moved all libic-related drawing into cairo_image_surface.c. Details below: * src/cairo_xlib_surface.c: Add width, height, format to cairo_xlib_surface_t. (_cairo_xlib_surface_get_image): (_cairo_xlib_surface_set_image): Implement new get_image/set_image interface instead of pull_image/push_image. (_cairo_xlib_surface_get_image): Fix memory leak that showed up with non-Render servers. (_cairo_xlib_surface_set_matrix): Implement set_matrix with new interface. (_render_operator): Translate from cairo_operator_t to Render-defined operator values rather than assuming they are the same. * src/cairo_surface.c: Move all libic-related code into cairo_image_surface.c. cairo_surface is now a thin wrapper around concrete surface types, (with fallback code to cairo_image_surface whenever a backend does not provide support for a particular function). Remove checks for NULL backend functions. (_cairo_surface_get_image): (_cairo_surface_set_image): New interface to replace pull_image/push_image. Now uses a cairo_image_surface rather than an IcImage and now also passes it externally rather than storing it in the surface. * src/cairo_gstate.c (_cairo_gstate_fini): (_cairo_gstate_set_target_surface): (_cairo_gstate_set_rgb_color): Avoid useless calls to cairo_surface_destroy for NULL surfaces. (_cairo_gstate_show_surface): (_cairo_gstate_clip): (_cairo_gstate_clip_and_composite_trapezoids): (_cairo_gstate_begin_group): Add status checking for calls to surface_create_similar, surface_fill_rectangles, surface_composite, and surface_composite_trapezoids. * src/cairo_ft_font.c (_cairo_ft_font_show_glyphs): Remove one gratuitous level of nesting. (_cairo_ft_font_show_glyphs): Bubble up NULL_MEMORY status. * src/cairo.h: Portability improvements: Remove include of X11/extensions/Xrender.h. Move include down near the freetype include. cairo_format_t: Eliminate Render-based values for this enum. cairo_operator_t: Eliminate Render-based values. Drop disjoint/conjoint operators. cairo_filter_t: Eliminate libic-based values for this enum. Add cairo_image_surface_create and cairo_image_surface_create_for_data. * src/cairo.c (cairo_status_string): Add new CAIRO_STATUS_NULL_POINTER. This can be returned only if the user passes a NULL object in to a cairo function. * src/cairoint.h: Move include of from cairo.h to here. * src/Makefile.am (libcairo_la_SOURCES): Add cairo_image_surface.c. Reformat line continuation characters. * src/cairoint.h: Remove prototypes for obsolete functions: _cairo_gstate_set_visual and _cairo_gstate_set_format. 2003-10-30 Carl Worth * src/cairo_xlib_surface.c (_cairo_xlib_surface_destroy): Fix memory leaks of surface->gc and surface->ximage. (_cairo_xlib_surface_composite): (_cairo_xlib_surface_composite_trapezoids): Fix memory leaks of cloned surfaces. 2003-10-30 Carl Worth * configure.in (CAIRO_VERSION): Bumped version to 0.1.9 for change in argument list of cairo_ft_font_create. * src/cairo_ft_font.c: A set of changes to eliminate the static FT_Library field, (which could introduce nasty problems with respect to threading). With the new code, each font created with the toy API will own its own FT_Library. Meanwhile, cairo_ft_font_create now accepts an FT_Library parameter. * src/cairo_ft_font.c: Add ft_library field so that fonts that own their own FT_Library can also clean it up. Eliminate static FT_Library and _init_cairo_ft_lib. (cairo_ft_font_create): Now accepts an FT_Library argument. (_cairo_ft_font_create): Create an FT_Library owned by this font, (this only happens as part of the "toy API") (_cairo_ft_font_destroy): Clean up ft_font->ft_library if necessary. (cairo_ft_font_create_for_ft_face): Initialize ft_library and owns_ft_library. * src/cairo.h: Add FT_Library parameter to cairo_ft_font_create. 2003-10-30 Carl Worth * cairo_font: A few cleanups to eliminate a memory leak. * src/cairo_gstate.c (_cairo_gstate_init_copy): (_cairo_gstate_fini): (_cairo_gstate_select_font): (_cairo_gstate_set_font): Replace calls to _cairo_font_fini with cairo_font_destroy. * src/cairo_ft_font.c (_cairo_ft_font_destroy): Rename _cairo_ft_font_close to _cairo_ft_font_destroy. * src/cairo_font.c: Eliminate unnecessary cairo_font_fini function. (cairo_font_destroy): Put reference decerement here where it belongs. * src/cairoint.h: Eliminate unnecessart family, slant, and weight fields from cairo_font_t. Rname font backend->close to backend->destroy. 2003-10-28 Carl Worth * README: Updated to match latest text from web page. Fixed stale references to Xc and xrtest. 2003-10-28 Carl Worth * src/cairo_xlib_surface.c (_cairo_xlib_surface_pixels_per_inch): Implement new backend function. * src/cairo_surface.c (_cairo_surface_pixels_per_inch): Add new function to query surface pixels_per_inch. * src/cairo_gstate.c (_cairo_gstate_init): Rename gstate->ppm to gstate->pixels_per_inch. Swithc from default 3780 pixels per meter to 96.0 pixels per inch which is slightly different. 2003-10-28 Carl Worth * src/cairo_gstate.c (_cairo_gstate_ensure_source): (_cairo_gstate_clip_and_composite_trapezoids): (_cairo_gstate_clip): (_cairo_gstate_show_surface): Track changes to _cairo_surface_create_similar_solid. * src/cairo_surface.c (_cairo_surface_create_similar_solid): Now that this function is internal, it can accept a cairo_color_t which makes the interface much cleaner. * src/cairo.h: Remove problematic function cairo_surface_create_similar_solid from the public API. 2003-10-28 Carl Worth * src/cairo_surface.c (_cairo_surface_composite): (_cairo_surface_fill_rectangles): (_cairo_surface_composite_trapezoids): Fix bug introduced in last commit: must check for NULL backend function before calling through it. 2003-10-27 Carl Worth * src/cairo_surface.c (_cairo_surface_composite): (_cairo_surface_fill_rectangles): (_cairo_surface_composite_trapezoids): backend functions must not be NULL. Track new cairo_int_status_t return value for backend drawing functions. * src/cairo_xlib_surface.c: Remove casts when initializing cairo_xlib_surface_backend. Rename cairo_xlib_surface as cairo_xlib_surface_t. (_cairo_xlib_surface_create_similar): (_cairo_xlib_surface_destroy): (_cairo_xlib_surface_pull_image): (_cairo_xlib_surface_push_image): (_cairo_xlib_surface_set_matrix): (_cairo_xlib_surface_set_filter): (_cairo_xlib_surface_set_repeat): (_cairo_xlib_surface_composite): (_cairo_xlib_surface_fill_rectangles): (_cairo_xlib_surface_composite_trapezoids): Track changes in cairo_surface_backend API. * src/cairoint.h: cairo_surface_backend now accepts a void * for the virtual surface. 2003-10-27 Carl Worth * src/cairo_ft_font.c (_cairo_ft_font_create): Default to normal slant/weight on out-of-range values. Add missing include of fontconfig/fcfreetype.h. 2003-10-24 Keith Packard * src/cairo_ft_font.c: (_cairo_ft_font_show_glyphs): A HORRIBLE KLUDGE to repad glyph images from freetype to meet libic requirements. 2003-10-24 Carl Worth * src/cairo_ft_font.c (_init_cairo_ft_lib): Fix missing void from function prototype. (_utf8_to_ucs4): Mark static. * src/cairo_xlib_surface.c: Remove unused function _cairo_xlib_surface_get_picture. * src/cairo_ft_font.c (_cairo_ft_font_copy) (_cairo_ft_font_glyph_extents, _cairo_ft_font_glyph_path): Internal functions can't receive a NULL font pointer. * src/cairo.c (cairo_text_extents, cairo_glyph_extents) (cairo_text_path, cairo_glyph_path): Comment-out functions without complete implementations to squelch compiler warnings. * configure.in: Bump version to 0.1.8 for font API changes. * src/cairo.c (cairo_current_font): Fix missing return value. * src/cairoint.h: No need for CAIRO_INT_STATUS_NULL_POINTER (CAIRO_FONT_BACKEND_DEFAULT): Move declaration of default font backend up into cairoint.h * src/cairo_gstate.c (_cairo_gstate_init): Create a default font, don't leave it NULL. (_cairo_gstate_current_font): gstate->font must never be NULL.

(_cairo_font_init, _cairo_font_scale, _cairo_font_transform) (_cairo_font_text_extents, _cairo_font_glyph_extents) (_cairo_font_show_text, _cairo_font_show_glyphs) (_cairo_font_text_path, _cairo_font_glyph_path) (_cairo_font_font_extents): These internal functions can never be called with a NULL font. 2003-10-23 Graydon Hoare * src/cairo_ft_font.c: New file. * src/Makefile.am: Add cairo_ft_font.c * src/cairo.c: * src/cairo.h: * src/cairo_font.c: * src/cairo_gstate.c: * src/cairo_xlib_surface.c: * src/cairoint.h: Change to virtual font interface. 2003-10-23 Carl Worth * TODO: Added notes on some missing functions. Update PostScript comparison with respect ot new arc functions. 2003-10-23 Carl Worth * Many files: Fixed Copyright statements to read "University of Southern California" rather than "USC, Information Sciences Institute" as the university is the actual corporation. 2003-10-11 Carl Worth * src/cairo-xlib.h: Add extern "C" stuff. (Thanks to Soory Kuloor for the reminder). 2003-10-09 Carl Worth * src/cairo_font.c: Stub out NULL_POINTER errors as CAIRO_STATUS_SUCCESS so that drawing to off-screen images still works even though text does not yet. 2003-10-04 Carl Worth * src/cairo_hull.c (_cairo_hull_compute): Add cairo_hull.c to compute a convex hull, (using Graham scan algorithm). * src/cairo_pen.c (_cairo_pen_add_points): Generate convex hull of pen after adding new points. * src/cairoint.h: Rename pen->vertex to pen->vertices * Replaced "pt" with "point" in about a zillion places. * src/cairo.c (cairo_destroy): Fix to continue with destroy even in the face of non-zero status.

Consolidated cairo_path_direction_t and cairo_pen_stroke_direction_t into cairo_direction_t. Removed accidental addition of two _print_svg functions that had been used for debugging temporarily. 2003-09-25 Carl Worth * configure.in (CAIRO_VERSION): Bumped version to 0.1.5 to indicate removal of cairo_path_t and related functions. * src/cairo.h: Decided that we don't actually need any of the cairo_path_t functionality exposed in the commit earlier today. Ripped all of that back out. * configure.in (CAIRO_VERSION): Bumped version to 0.1.4 for new exposed cairo_path_t and related functions. * src/cairo_path.c (cairo_path_create): (_cairo_path_copy): (cairo_path_destroy): New create/copy/destroy functions for paths. (_cairo_path_init): Added current_pt state to cairo_path_t. (cairo_path_rel_move_to): (cairo_path_rel_line_to): (cairo_path_rel_curve_to): Added relative path creation functions, (relative stufff used to be done internally in cairo_gstate).

(_cairo_surface_pull_image): (_cairo_surface_push_image): First real implementation of push/pull_image, (thanks for help from Graydon Hoare ). This provides support for running Cairo on X servers that do not have the RENDER extension. (Note: This is still woefully slow). * src/cairo_path_stroke.c (_cairo_stroker_join): Switch to _cairo_fixed functions. * src/cairo_path_bounds.c (_cairo_path_bounds): Use cairo_fixed rather than X macros. * src/cairo_gstate.c (_cairo_gstate_current_point): If not explicitly set, current point is (0,0) in user space. (_cairo_gstate_show_text): Fix to place text at user-space origin if there is no current point. (_cairo_gstate_show_surface): Optimize to pass NULL mask if alpha == 1.0. (_cairo_gstate_show_surface): Fixe to use current_point rather than (0,0). * src/cairo.h: Removed cairo_surface_put_image. * src/Makefile.am (libcairo_la_SOURCES): Added cairo_fixed.c 2003-09-05 Keith Packard * src/cairo_path_stroke.c: comment face computations, check for reflecting transformation to select correct face orientations * src/cairo_pen.c: check for reflecting transform when computing pen to ensure consistent pen orientation 2003-09-05 Carl Worth * configure.in: Bumped version to 0.1.2 for new cairo_copy function. * src/cairo_gstate.c (_cairo_gstate_init): Fixed uninitialized current_pt values. (_cairo_gstate_clone): Force gstate->next to NULL after cloning, to prevent the clone from trashing the former stack. * src/cairo.c (cairo_create): Folded _cairo_init into cairo_create. (cairo_destroy): Folded _cairo_fini into cairo_dstroy. (cairo_copy): Added new cairo_copy function. 2003-09-05 Carl Worth * src/cairo_gstate.c (_cairo_gstate_show_text): Fix crash due to missing call to ensure_source. 2003-09-04 Carl Worth * src/cairoint.h (DEPRECATE): Changed DEPRECATE mechanism to preseve binary compatibility, but break source-level compatibility. 2003-09-04 Carl Worth * src/cairo_gstate.c (_cairo_gstate_init): Combine gstate->pattern and gstate->solid into a single gstate->source. (_cairo_gstate_set_rgb_color): Defer creation of gstate->source until the stroke or fill. (_cairo_gstate_ensure_source): New function to combine duplicated code.

This is a clean solution to the bug of a SEGV if cairo_stroke/cairo_fill are called before cairo_set_target. * BUGS: Removed two fixed bugs, (SEGV if cairo_set_rgb_color called before cairo_set_target and SEGV if cairo_fill called before cairo_set_rgb_color) 2003-09-04 Keith Packard * src/cairo_path_stroke.c: added comments describing miter join code and miter limit computation. Replace XFoo with cairo_foo for double and fixed * src/cairoint.h: add cairo_fixed_to_double and cairo_double_to_fixed Carl says he's got similar code, so he'll have to fix things if I get this committed quickly enough. 2003-09-04 Carl Worth * util/cairo-api-update: Added script to update source code using Cairo to the latest API. * configure.in (CAIRO_VERSION): Bumped version to 0.1.1 * src/cairoint.h (DEPRECATE): Added magic DEPRECATE macro which provides an asm-based alias for old function names. This works on ELF systems with gcc version >= 2. * src/cairo.h (cairo_get_status_string): Deprecated all cairo_get_* names in favor of cairo_current_*. The deprecated function names will trigger either a warning or a link error, but in both cases with a useful message giving both the old and new name of the function. Three of the function name changes are different than the single word substituion: cairo_get_current_color -> cairo_current_color cairo_get_status -> cairo_status cairo_get_status_string -> cairo_status_string 2003-09-03 Carl Worth * src/cairo.h: Change cairo_get_matrix interface to accept a cairo_matrix_t* rather than 6 double*. * src/cairo.c (cairo_get_matrix): Add implementation of cairo_get_matrix. 2003-08-29 Carl Worth * src/cairo_surface.c (_cairo_surface_composite): Optimized case where src is in memory, dst is on server, and mask is NULL. Will now do a single XPutImage rather than the painful GetImage/PutImage dance of the general code. 2003-08-28 Carl Worth * src/cairo_traps.c (_line_segs_intersect_ceil): One more increment, (that still won't fix the bug). Added comment point to Hobby's paper, (that will fix it). * src/cairo_font.c (_cairo_font_resolve_xft_font): Fixed to use fabs instead of abs when correcting for negative area expansion. 2003-08-28 Keith Packard * src/cairoint.h: Added missing underscores to several internal functions. * src/cairo_font.c: * src/cairo_gstate.c: * src/cairo_matrix.c: * src/cairo_path_fill.c: * src/cairo_path_stroke.c: * src/cairo_pen.c: * src/cairo_traps.c: Fixed to track newly added underscores. * src/cairo.h: Some whitespace fixes. * src/cairo_gstate.c (_cairo_gstate_set_pattern): Fixed to anchor pattern at current point instead of the origin. (_cairo_gstate_stroke): Fixed to properly transform pattern. (_cairo_gstate_fill): Fixed to properly transform pattern. 2003-07-31 Richard Henderson * src/cairo_color.c (CAIRO_COLOR_DEFAULT): Mark const. * src/cairo_matrix.c (CAIRO_MATRIX_IDENTITY): Likewise. * src/cairo_path.c (num_args): Likewise. * src/cairo_path_bounds.c (_cairo_path_bounds): Likewise for cb. 2003-07-31 Richard Henderson * cairo.pc.in: Depend on slim. * configure.in: Check for slim. * src/cairo.h: Include slim_{export,import}.h as needed; mark all symbols __external_linkage. * src/cairoint.h: Include slim_internal.h; mark all symbols __internal_linkage. Provide slim_hidden_proto symbols as needed. * src/cairo.c, src/cairo_matrix.c, src/cairo_surface.c, Provide slim_hidden_def symbols as needed. * src/cairo_traps.c (cairo_traps_add_trap): Mark static. (cairo_traps_add_trap_from_points): Likewise. 2003-07-30 Carl Worth * configure.in (LIBIC_REQUIRED): Fixed some typos in the libic PKG_CHECK. * src/cairoint.h: * src/cairo.c: Fixed a disagreement over whether some internal cairo_gstate_t functions had an '_' prefix or not. * src/cairo_traps.c (_line_segs_intersect_ceil): Add one more conditional intersect to push past some fill bugs. * src/cairo_surface.c (cairo_surface_create_for_drawable): (cairo_surface_create_for_image): (cairo_surface_put_image): (_cairo_surface_pull_image): (_cairo_surface_push_image): (cairo_surface_set_matrix): (cairo_surface_get_matrix): (cairo_surface_set_repeat): (_cairo_surface_composite): (_cairo_surface_fill_rectangle): (_cairo_surface_fill_rectangles): (_cairo_surface_composite_trapezoids): Absorb all functionality previously in the Xc library. * src/cairo_pen.c (_cairo_pen_init): Don't store floating point theta in the pen. Instead, sort vertices by fixed point slope comparisons. (_cairo_pen_add_points): Fixed to remove duplicate pen vertices appearing at beginning and end of vertex array. (_pen_vertex_compare): New fixed-point "angle" comparison for pen vertices. A bit trickier than before, but much more accurate. * src/cairo_path_stroke.c (_cairo_stroker_face_clockwise): Share clockwise calculation with other modules. * src/cairo_path_bounds.c: * src/cairo_path_fill.c: * src/cairo_path_stroke.c: * src/cairo_pen.c: * src/cairo_polygon.c: * src/cairo_spline.c: * src/cairo_traps.c: * src/cairo_path.c: Replaced all references to XFixed, XPointFixed, XLineFixed, and XTrapezoid with new cairo_fixed_t, cairo_point_t, cairo_line_t, and cairo_trapezoid_t. * src/cairo_path.c: (_cairo_path_interpret): Made the path interpreter callback names consistent, (eg. add_edge rather than AddEdge). * src/cairo_gstate.c (_cairo_gstate_text_extents): Now silently exits for a non X surface, (avoids a crash until we can implement the libic text backend). * src/cairo_gstate.c (_cairo_gstate_end_group): (_cairo_gstate_clip_and_composite_trapezoids): (_cairo_gstate_show_surface): Replaced all XcCalls with corresponding cairo_surface_calls. * src/cairo_gstate.c (_cairo_gstate_transform_point): (_cairo_gstate_transform_font): (_cairo_gstate_text_extents): Renamed from the garbled names (eg. cairo_gstateransform_point) leftover from the great renaming. * src/cairo_color.c (_cairo_color_set_rgb): Reworked cairo_color_t to eliminate reference to an XcColor object. * src/cairo.h: Dropped include of , added , , and * src/cairo.c (cairo_get_fill_rule): Added missing cairo_get_fill_rule. * configure.in (PKG_CHECK_MODULES): Drops xc, add libic * cairo.pc.in (Requires): Drop xc, add libic. 2003-07-25 Carl Worth * src/cairo_traps.c (_line_segs_intersect_ceil): We don't need a loop here, (just a conditional increment). This time, we've actually done the error analysis to back this up. 2003-07-24 Carl Worth * src/cairo_traps.c (cairo_traps_tessellate_polygon): Massive cleanup of polygon tessellation, (it might actually be correct now). 2003-07-23 Carl Worth * src/cairoint.h: Introduced some cairo_fixed_*_t types. This is the first baby step toward ripping X dependencies out of the Cairo headers. * src/cairo_traps.c (_compute_x): Converted from floating point to fixed point. (_line_seg_intersection_ceil): Now increments y value once if the initial y value computed is less than the actual intersection point. * src/cairo_traps.c (_compare_cairo_edge_by_slope): Converted from floating point to fixed point. * src/cairo_pen.c (_slope_clockwise): Converted from floating point to fixed point. 2003-07-19 Carl Worth * src/cairo_traps.c (cairo_traps_tessellate_polygon): Fixed some sorting problems with two intersections very near the same vertical position. (There are still some reamining problems though). (cairo_traps_tessellate_polygon): Better fix for the same bug. Should cover all cases, (and it's moe efficient too). 2003-07-18 Carl Worth * src/cairo.h: Fixed some inconsistent tag/typedef names that were missed in the great renaming. 2003-07-18 Carl Worth * src/cairo.h: Renamed everything from Xr* to cairo_*. * util/xr2cairo: Added utility script xr2cairo to help users fix their source code. 2003-07-03 Carl Worth * src/xrmatrix.c (XrMatrixGetAffine): Added XrMatrixGetAffine (from Soorya Kuloor) * src/xr.c (XrGetAlpha): Added XrGetAlpha (XrGetRGBColor): Added XrGetRGBColor 2003-06-12 Carl Worth * src/xrgstate.c (_XrGStateScale): Scale by 0 now causes an InvalidMatrix error. 2003-05-28 Carl Worth * src/xrmatrix.c (XrMatrixMultiply): Eliminated _XrMatrixMultiplyIntoRight and _XrMatrixMultiplyIntoLeft. * src/xrgstate.c (_XrGStateClipAndCompositeTrapezoids): Fixed missing translation of clip surface. * src/Xr.h: Added XrSurfacePutImage 2003-05-16 Carl Worth * src/xrint.h: Added ppm filed (pixels per meter) to both XrSurface and XrGState. * src/xrgstate.c (_XrGStateSetTargetSurface): Fixup CTM according to change in surface->ppm. (_XrGStateDefaultMatrix): Default matrix is no longer an identity matrix, but rather a matrix that provides some relates user space units to real-world dimensions in a meaningful way, (default 3780 user space units per meter). This conversion is not exact, but is rather as close as possible while also guaranteeing that one user space unit maps to an integer number of device pixels. 2003-05-15 Carl Worth * src/xr.c (XrSetTargetDrawable): Moved implementation up from _XrGStateSetTargetDrawable, (eg. all convenience functions should be taken care of at the xr.c level ratehr than xrgstate.c) * src/Xr.h: Added convenience function XrSetTargetImage 2003-05-14 Carl Worth * src/xrfont.c (_XrFontResolveXftFont): Fixed fonts to pull pixelsize out of the transformation matrix. Fonts are now properly hinted regardless of scaling. * src/Xr.h: Three new functions for manipulating surfaces: XrSurfaceSetMatrix, XrSurfaceGetMatrix, XrSurfaceSetFilter. * src/Xr.h: Removed broken XrShowImage* functions. Changed XrShowSurface to not require X/Y but instead depend on the CTM for translation, (or the surface transformation matrix). I'd like to get rid of width/height as well but it turns out an XrSurface is not aware of its dimensions. * src/Xr.h: Added convenience function for building rectangular paths: XrRectangle. * src/Xr.h: Added functions for performing transformations with the CTM and its inverse: XrTransformPoint, XrTransformDistance, XrInverseTransformPoint, XrInverseTransformDistance. * src/Xr.h: XrConcatMatrix and XrSetMatrix now accept a pointer to an XrMatrix rather than 6 doubles. * src/Xr.h: Now exporting opaque XrMatrix object with several functions: XrMatrixCreate, XrMatrixDestroy, XrMatrixCopy, XrMatrixSetIdentity, XrMatrixSetAffine, XrMatrixTranslate, XrMatrixScale, XrMatrixRotate, XrMatrixInvert, XrMatrixMultiply, XrMatrixTransformDistance, XrMatrixTransformPoint. 2003-05-12 Carl Worth * src/Xr.h: Added XrSetPattern. See also XrSurfaceSetRepeat. * src/xrpathbounds.c (_XrPathBounds): Moved path bound computation to its own file. * src/xrpathstroke.c (_XrPathStrokeToTraps): Moved path stroking to its own file. * src/xrpathfill.c (_XrPathFillToTraps): Moved path fililng to its own file. * src/xrgstate.c (_XrGStateStroke): (_XrGStateFill): (_XrGStateClipAndCompositeTrapezoids): Reorganized stroke and fill code to go through the same path for clipping. 2003-05-02 Carl Worth * src/Xr.h: Changed XrFormatRGB32 to XrFormatRGB24 * src/xrsurface.c (_XrFormatBPP, XrSurfaceCreateForImage) (_XrFormatDepth): Fixed for change of XrFormatRGB32 to XrFormatRGB24 2003-05-01 Carl Worth * src/xrpath.c (_XrPathBounderInit): (_XrPathBounderDeinit): (_XrPathBounderAddPoint): (_XrPathBounderAddEdge): (_XrPathBounderAddSpline): (_XrPathBounderDoneSubPath): (_XrPathBounderDonePath): (_XrPathBounds): New support for computing the bounding box of a path. Currently used internally, (for computing the size of the clip surface), and not exported publically. * src/xrgstate.c (_XrGStateStroke): Implemented clip support for strokes. (_XrGStateClip): New _XrGStateClip function fills the current path onto the gstate->clip surface. * src/xr.c (XrClip): Added preliminary/experimental clip functionality. The current implementation only clips stroked elements, (not fills, images, or text). It's alway quite inefficeient. * src/xr.c (XrGetOperator): (XrGetTolerance): (XrGetLineWidth): (XrGetLineCap): (XrGetLineJoin): (XrGetMiterLimit): (XrGetCurrentPoint): Added several new query functions. 2003-04-26 Carl Worth * src/xrsurface.c (XrSurfaceDestroy): Fix memory leak of surface->image_data. 2003-04-25 Carl Worth * configure.in: Fixed libtool versioning 2003-04-17 Carl Worth * Switched from imake to autotools. * src/xrint.h: XrSurface structure is now greatly simplified, (details now handled by XcSurface). * src/Xr.h: Eliminated Display * parameter so Xr can be used for non-X drawing. Removed XrPushGroup/XrPopGroup. Replaced XrSetDrawable/XrSetVisual with XrSetTargetDrawable. Added XrSetTargetSurface and several new XrSurfaceCreate functions. Added XrShowSurface, (functionality overlaps with XrShowImage -- need to fix this) 2003-02-14 Carl Worth * xrgstate.c (_XrGStateShowImageTransform): Fixed transformed images which were sometimes 1 pixel too tall/wide. 2003-02-06 Carl Worth * xrpen.c (_XrPenVerticesNeeded): Fixed to use determinant rather than eigenvalues to compute maximal scaling of radius. Now avoids embarrassing segfaults due to NaN from the eigenvalue computation. 2003-01-28 Carl Worth * xrtraps.c (_XrTrapsTessellateTriangle): Fixed to not re-order the array provided as an argument. (Note: the rectangle and polyghon tessellators still perform reordering). * xrstroker.c (_XrStrokerJoin): (_XrStrokerCap): Implemented round caps and joins. (_XrStrokerDoneSubPath): Fixed initial cap, (was always being drawn on the inside previously). * xrpen.c (_XrPenInit): Fixed to keep pen vertex theta values all in device space. (_XrPenAddPoints): Removed the silly flags from the pen vertices, (in favor of just using the FindActiveVertex functions) (_XrPenFindActiveCWVertexIndex): (_XrPenFindActiveCCWVertexIndex): Added functions needed for round caps/joins. * xrgstate.c (_XrGStateSetDash): Fixed to accept a NULL dash array to revert to no dashing. 2003-01-28 Carl Worth * xrtraps.c (_XrTrapsTessellateTriangle): Restored triangle tessellation functionality, (I think it's correct this time). * xrstroker.c (_XrStrokerJoin): Bevel joins now use triangle tessellation rather than polygon tessellation. 2003-01-24 Carl Worth * xrpolygon.c (_XrPolygonAddEdge): Fixed to handle multiple sub-polygons. * xrstroker.c (_XrStrokerJoin): Fixed handling of miter limit. * local.def: Added local.def for building outside the xc tree. 2002-12-03 Carl Worth * xrstroker.c (_XrStrokerJoin): (_XrStrokerCap): Fixed to track change in winding rule parameter to XrTrapsTessellatePolygon, (otherwise self-intersecting splines suddenly had holes). * xrpen.c (_XrPenStrokeSpline): Fixed to track change in winding rule parameter to XrTrapsTessellatePolygon. 2002-11-11 Carl Worth * xrtransform.c (_XrTransformBoundingBox): Added support for transforming a bounding box, (an axis-aligned rectangle prior to transformation). The ShowImage support needs this. (_XrTransformComputeInverse): Now catches error case for non-invertible matrix. * xrsurface.c (_XrSurfaceSetTransform): Fixed ordering of matrix for call to RenderSetPictureTransform * xrgstate.c (_XrGStateSetMatrix): (_XrGStateIdentityMatrix): Support for new Xr matrix functions. (_XrGStateShowImage): (_XrGStateShowImageTransform): Fixed transformation of images. * xr.c (XrSetMatrix): (XrDefaultMatrix): (XrIdentityMatrix): Added 3 matrix manipulation functions. 2002-11-04 Carl Worth * xrsurface.c (_XrSurfaceDereference): (_XrSurfaceDereferenceDestroy): Fixed bug in reference counting logic. (_XrSurfaceSetDrawableWH): XrSurface now keeps track of its width/height. (_XrSurfaceGetDrawable): (_XrSurfaceGetWidth): (_XrSurfaceGetHeight): (_XrSurfaceGetDepth): New accessor functions. * xrgstate.c (_XrGStateBeginGroup): (_XrGStateEndGroup): Preliminary group support. Not too efficient since it always composite's a full-size picture from child group to parent picture, (even if only a small portion has non-transparent pixels). (_XrGStateShowImageTransform): Fixed show image to use current alpha value. * xrfont.c (_XrFontResolveXftFont): Fixed memory leak (FcPatternDestroy). There's still some meory leaking/left-reachable in Xft/fontconfig that I need to track down. * xr.c (XrPushGroup): (XrPopGroup): Added preliminary group support. I think I like having this in the API as it takes several burdens away from the user, (plus it matches the PDF model). Things to do still: think about the names of these functions. Re-read the PDF semantics to see if we're missing anything. 2002-11-02 Carl Worth * xrsurface.c (_XrSurfaceSetImage): Fixed leak of the image pixmap. 2002-11-01 Carl Worth * xrsurface.c (_XrSurfaceSetImage): Prelimary image support. Really only works with ARGB32. I still need to think about what formats will be supported. (_XrSurfaceSetTransform): Partial support for transformed surfaces. (_XrSurfaceGetXcSurface): Moved all creation/destruction of the XcSurface into this function so that it is only lazily created when needed. * xrgstate.c (_XrGStateSetCurrentPt): gstate now can throw errors when an operation needs current point, but it doesn't exist yet. (_XrGStateShowImage, _XrGStateShowImageTransform): Preliminary image support, (currently it only scales according to the CTM. The matrix passed with the image doesn't do anything yet.) * xrfont.c (_XrFontInitCopy): Removed bogus out of memory errors. * xr.c (XrShowImage, XrShowImageTransform): Added very preliminary image support. Things don't work completely yet and all the interfaces are likely to change. (XrGetStatusString): Added function to map status values to strings. 2002-10-31 Carl Worth * xrfont.c (_XrFontInit): (_XrFontInitCopy): (_XrFontDeinit): (_XrFontSelect): (_XrFontResolveXftFont): Updated by ripping all font support from Xc and just putting a couple of calls to Xft and fontconfig right here in xrfont. * xr.c (XrTextExtents): Added XrTextExtents. 2002-10-29 Carl Worth * xrgstate.c (_XrGStateSelectFont, _XrGStateScaleFont) (_XrGStateTransformFont, _XrGStateShowText): Added basic font support. * xr.c (XrSelectFont, XrScaleFont, XrTransformFont): Added basic font support. 2002-10-28 Carl Worth * xrstate.c (_XrStatePop): Added error case for XrRestore without matching XrSave. * xrsurface.c (_XrSurfaceInit, _XrSurfaceReference) (_XrSurfaceDereference): Added reference counting to XrSurface to patch a memory leak. 2002-10-26 Carl Worth * xrtransform.c (_XrTransformDistance): (_XrTransformPoint): changed to use individual X/Y arguments rather tha an XPointDouble. This improves readability since _XrTransformDistance is now always called with arguments of dx/dy rather than pt.x/pt.y. * xrpath.c (_XrPathMoveTo): (_XrPathLineTo): (_XrPathCurveTo): (_XrPathClosePath): replaced public _XrPathAdd with explicit named functions. This cleans up the implementation since _XrPathAdd, which is unsafe with respect to argument consistency, is now private. Also, since the _XrGState now maintains the current point, I dropped all relative path operators from the XrPath data structures. * xrgstate.c (_XrGStateMoveTo): (_XrGStateLineTo): (_XrGStateCurveTo): (_XrGStateRelMoveTo): (_XrGStateRelLineTo): (_XrGStateRelCurveTo): Replaces _XrGStateAddPathOp and _XrGStateAddUnaryPathOp with explicit named functions for each operator type. This change introduces the current point state into the XrGState structure rather than postponing its calculation until path interpretation. * xrgstate.c (_XrGStateSetDrawable): (_XrGStateSetVisual): (_XrGStateSetFormat): (_XrGStateSetOperator): (_XrGStateSetRGBColor): (_XrGStateSetTolerance): (_XrGStateSetAlpha): (_XrGStateSetFillRule): (_XrGStateSetLineWidth): (_XrGStateSetLineCap): (_XrGStateSetLineJoin): (_XrGStateSetMiterLimit): (_XrGStateTranslate): (_XrGStateScale): (_XrGStateRotate): (_XrGStateConcatMatrix): (_XrGStateNewPath): : Added XrStatus return values to many functions -- just for consistency, these functions can not return errors in any case. * xr.c (XrShowText): Started to ass XrShowText, (still not functional) 2002-10-24 Carl Worth * xr.c (XrSetFillRule): Added support to set fill rule. 2002-10-23 Carl Worth * xrtraps.c (_XrTrapsTessellatePolygon): Fix for polygon with multiple sub-polygons that are disjoint in Y. 2002-07-16 Carl Worth * Xr.h: Renamed xrpicture.c to xrsurface.c as part of the move. Added XrSetFormat, XrSetOperator, XrSetLineCap, XrSetLineJoin, and XrSetMiterLimit, (although the line style drawing code is not all in place yet). * xrpath.c (XrPathLineTo): Changed LineTo semantics to be the same as MoveTo if there was no previous MoveTo. * xrtraps.c: Added tessellation code, (lifted from XRenderCompositeDoublePoly which can now disappear). * xrgstate.c: Changed stroke code to incrementally build a list of trapezoids rather than forming one giant polygonal outline and rendering that. This should be more efficient. (_XrGStateFillPath): Now uses Xr's own tessellation along with XcCompositeTrapezoids. * Xr.h: Moved all of Xr away from Xrender to the new Xc library. * xrsurface.c: Renamed from xrpicture.c, (part of the move from XRender to Xc). * Started keeping a ChangeLog ;-)
