(_cairo_gstate_show_surface): Don't change the surface matrix here, it's done later when we set it up as a pattern. * test/Makefile.am: Correct clip_twice-ref.png filename. * src/cairoint.h (MIN, MAX): Add these. * src/cairo_gstate.c (_cairo_rectangle_intersect): Fix broken intersection code. 2005-01-27 Kristian Høgsberg * src/cairo_pattern.c (_cairo_pattern_get_surface): Make sure we always return a surface similar to dst in the gradient case. * src/cairo_pattern.c (_cairo_pattern_get_surface): Fold _cairo_pattern_get_image into _cairo_pattern_get_surface and make sure we always return a surface of the same type as dest. * src/cairo_glitz_surface.c (_cairo_glitz_composite), (_cairo_glitz_surface_composite_trapezoids): Use _cairo_pattern_get_surface instead of _cairo_pattern_get_image. * src/cairo_xlib_surface.c (_cairo_xlib_surface_show_glyphs), (_cairo_xlib_surface_composite) (_cairo_xlib_surface_composite_trapezoids): Remove use of _cairo_xlib_surface_clone_similar since _cairo_pattern_get_surface always gives us an xlib surface for the pattern. Clean up error handling code in _cairo_xlib_surface_show_glyphs. * src/cairo_image_surface.c (_cairo_image_surface_composite): (_cairo_image_surface_composite_trapezoids): Add missing cairo_surface_destroy and tidy up offset calculations as suggested by Owen. * src/cairoint.h (cairo_clip_rect_t): * src/cairo_gstate.c (_cairo_gstate_clip_and_composite_trapezoids) (_cairo_gstate_clip, _cairo_gstate_show_glyphs): Simplify code for computing the extents of clipping area, by introducing a couple of cairo_rectangle_t functions. 2005-01-27 Owen Taylor * src/cairo.[ch] src/cairo_font.c src/cairo_ft_font.c src/cairo_ps_surface.c src/cairo_xlib_surface.c: Move docs from docs/reference, with a fair bit of addition and rewriting. * doc/reference/: Remove old-format docs. * configure.in: Add a AC_PREREQ(2.54) (Jason Dorje Short) 2005-01-27 Kristian Høgsberg * test/coverage-ref.png: * test/clip_twice-ref.png: Update these two once again, this time generated using libpixman-0.1.3 without leaky circles. 2005-01-27 Owen Taylor * configure.in Makefile.am docs/Makefile.am docs/public/*: Add framework for doing docs via gtk-doc. * src/cairo.[ch] src/cairo-matrix.c: Add some inline docs for arcs and matrices. * gtk-doc.m4 acinclude.m4: Check in files from gtk-doc to make the dependency on gtk-doc optional. * autogen.sh (LANG): Add --enable-gtk-doc to the default args. 2005-01-27 Kristian Høgsberg * test/write_png.c (unpremultiply_data): * test/read_png.c (premultiply_data): Fix missing rounding in these two functions. * test/coverage-ref.png: * test/clip_twice-ref.png: Update these to versions with properly rounded alpha values. * test/Makefile.am: Move clip_twice out of XFAIL now that rounding works. * test/.cvsignore: Add new test cases. 2005-01-27 Kristian Høgsberg The overall idea of this rewrite is that we want to pass the source pattern all the way down into the backends. 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.

Worth * src/Makefile.am: Add '-no-undefined' to end of libcairo_la_LDFLAGS to enable building shared library under cygwin. * src/cairo.h: Remove all 'extern ' and ' __external_linkage' (macro for __declspec(dllexport) and __declspec(dllimport)) from function declarations. These are no longer needed for cygwin. * src/cairo_traps.c: Changed type of _line_segs_intersect_ceil from 'static cairo_fixed_t' to 'static int' to match definition. This was necessary to compile under cygwin. 2003-12-17 Carl Worth * src/cairo.h: Remove trailing commas from enums, (some compilers like to complain about them). 2003-12-16 Dave Beckett * README: Do not require libpixregion, libic. 2003-12-16 Carl Worth * NEWS: Add more notes culled from the ChangeLog. 2003-12-16 Carl Worth * NEWS: Begin maintaining NEWS file.

Put create, copy, and destroy as the first functions in the list. Fix text_path and glyph_path so that the path to be returned is the last argument. Add x,y arguments to text_path. * src/cairo_gstate.c (_cairo_gstate_text_path): Compute x,y now needed by cairo_font_text_path. (_cairo_gstate_glyph_path): Track change in cairo_font_text/glyph_path (path argument is now last). * src/cairo_ft_font.c: Switch to new macro-based mechanism for including freetype headers.

Add note about broken dashing on splines. 2003-12-15 Carl Worth * src/cairo_gstate.c (_cairo_gstate_text_extents): (_cairo_gstate_glyph_extents): * src/cairo_ft_font.c (_cairo_ft_font_glyph_extents): (_cairo_ft_font_glyph_extents): * src/cairo.h: Rename cairo_text_exextents_t fields: left_side_bearing -> x_bearing ascent -> y_bearing right_side_bearing (replaced by) width descent (replaced by) height 2003-12-15 Carl Worth * src/cairo_gstate.c (_cairo_gstate_text_extents): (_cairo_gstate_glyph_extents): Need to divide out the scale factor to return user-space extents. (_cairo_gstate_glyph_extents): Don't transform glyph locations as they're not relevant to extents. * src/cairo_ft_font.c (_cairo_ft_font_font_extents): Clean up implementation. (_cairo_ft_font_glyph_extents): Initial implementation. Thanks to John Ellson for most of the work on this function.

(_cairo_gstate_show_glyphs): Fix to not reference current point. 2003-12-12 Dave Beckett * src/Makefile.am: Add compatibility defines FONTCONFIG_LIBS, X_LIBS, XRENDER_LIBS to keep automake happy - they look like automake variable names. 2003-12-12 Carl Worth * src/cairo_font.c (_cairo_font_create): Add comment about building in a font. * src/cairo_ft_font.c (_cairo_ft_font_create): Check for NULL return value from cairo_ft_font_create. * src/cairo.h: * src/cairo-features.h.in: * src/Makefile.am (libcairo_ps_sources): Add conditionals for ps_surface functions, etc. * configure.in: Get rid of AC_PATH_XTRA. Instead, find X includes/libraries only via pkg-config xrender.

Fix indentation problems left by the recent renaming. * Shift everything over from libic/libpixregion/slim to libpixman. Many thanks to Dave Beckett for all of the heavy lifting with this renaming effort. * src/cairoint.h (slim_hidden_proto1): Directly fold in slim stuff rather than depending on it from an external package. * src/cairo_ps_surface.c (_cairo_ps_surface_copy_page): * src/cairo_image_surface.c: Switch from libic to libpixman. * src/cairo.h: Include pixman.h not ic.h. (__external_linkage): Directly fold in slim stuff rather than depending on it from an external package. * configure.in (PKG_CHECK_MODULES): * cairo.pc.in (Requires): Look for libpixman instead of libic and slim. 2003-12-11 Andrew Chant * cairo_select_font: _cairo_font_create: _cairo_ft_font_create: _cairo_gstate_select_font: change char * family to const char * family 2003-12-11 Carl Worth * src/cairo_xlib_surface.c (_cairo_xlib_surface_set_image): Replace mysterious image->depth == 32 ? 24 : image->depth with simply image->depth. 2003-12-11 Carl Worth * cairo.pc.in (Requires): * configure.in: Add xrender to cairo.pc Renders line if needed. 2003-12-11 Carl Worth * src/cairo_ps_surface.c (_cairo_ps_surface_copy_page): Fix to use shifts and masks for endianness-correct PS image generation. Rename bgr to rgb now that the byte order issues are clear. 2003-12-08 Carl Worth * src/cairo_path_bounds.c (_cairo_path_bounder_move_to): (_cairo_path_bounder_line_to): (_cairo_path_bounder_curve_to): (_cairo_path_bounder_close_path): Track change in cairo_path_callbacks interface. * src/cairoint.h: * src/cairo_path_stroke.c: * src/cairo_path_fill.c: * src/cairo_path.c: Clean up cairo_path_callbacks to have move_to, line_to, curve_to, abd close_path instead of add_edge, add_spline, and done_sub_path. Much, much nicer. * src/cairo_polygon.c (_cairo_polygon_move_to): Provide cairo_polygon_move_to and cairo_polygon_line_to instead of cairo_polygon_add_point. * src/cairo_pen.c (_cairo_pen_stroke_spline_half): Track change in cairo_polygon interface. 2003-12-08 Carl Worth * configure.in: Bump version to 0.1.16 since it actually has a hope of building, (due to fix for broken cairo-xlib.h includes). 2003-12-05 Carl Worth * src/cairo_xlib_surface.c: Don't include obsolete cairo-xlib.h. * autogen.sh (AUTOCONF): Allow names of all autofoo programs to be overridden via environment variables. * configure.in: Bump version to 0.1.15 for new CAIRO_HAS_XLIB_SURFACE macro. * src/cairo.h: Add missing #include * Rename cairo-config.h to cairo-features.h. * configure.in: Rename XLIB_BACKEND_DEFINE to XLIB_SURFACE_FEATURE. Rename AM_CONDITIONAL HAVE_XLIB_BACKEND to CAIRO_HAS_XLIB_SURFACE. Rename user-visibile macro CAIRO_HAS_XLIB_BACKEND to CAIRO_HAS_XLIB_SURFACE. 2003-12-03 Carl Worth * configure.in: Bumped version to 0.1.14 to indicate dropped cairo-xlib.h and new cairo-config.h. * New support for "./configure --without-x" to compile without the xlib backend. 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. (INCLUDES, libcairo_la_LIBADD): Add the new variables from splitting up the PKG_CHECK_MODULES calls. 2003-12-03 Carl Worth * cairo.pc.in (Libs): Add -lz for the compress function used in the PS backend. 2003-12-01 Keith Packard * TODO: Add note about degenerate path caps being broken 2003-11-21 Carl Worth * src/cairo_polygon.c (_cairo_polygon_add_edge): Use 0 and 1 not False and True, (to avoid false dependency on X headers). * src/cairo_path_stroke.c (_compute_face): Use cairo_point_double_t not XPointDouble, (to avoid false dependency on X headers). Thanks to "Sasha V." for pointing these out. 2003-11-18 Carl Worth * configure.in: Bump version to 0.1.13 for new freetype header compatibility. 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.

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.

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_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.

(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.

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 ;-)
