Compute text extents by fetching one glyph metric at a time, transforming to user space and computing the overall bounding box. * src/cairo_matrix.c: (_cairo_matrix_set_rotate), (_cairo_matrix_compute_scale_factors): use 'sincos' where available. Scale factors now ensure the non-scale transform is area preserving.

Now avoid the warning by moving the * from the return type after the __internal_linkage macro. It looks awaful, but it keeps the compiler quiet. 2004-12-20 Alexander Larsson * src/cairoint.h: Add _cairo_gstate_restore_external_state, _cairo_fixed_integer_floor and _cairo_fixed_integer_ceil. * src/cairo.c: (cairo_restore): Call _cairo_gstate_restore_external_state on restore. * src/cairo_cache.c: (_cache_lookup): Fix cache-misses. * src/cairo_fixed.c: (_cairo_fixed_integer_floor), (_cairo_fixed_integer_ceil): Implement floor and ceil * src/cairo_gstate.c: (_cairo_gstate_restore_external_state): Restore surface clip region on restroe.

Add comment about remaining roundtrip and possible plans to eliminate it later with a new interface requiring width/height. Thanks to Alexander Larsson . * test/text_cache_crash.c (draw): Disabled test that was killing my machine for some reason. Scary. 2004-12-20 Carl Worth * src/cairo_image_surface.c (_cairo_image_abstract_surface_create_pattern): Change return value from cairo_status_t to cairo_int_status_t to match definition in cairo_surface_backend_t. * BUGS: Add bug about gcc 3.4 warning: '__visibility__' attribute ignored on non-class types. * src/cairoint.h: Remove __internal_linkage macro from all functions returning pointers to shut up warning from gcc 3.4. 2004-12-17 Carl Worth * test/cairo_test.c (cairo_test): Fix to find reference images in local directory when run directly, (rather than by "make check"). * BUGS: Add bug about invalidating font caches. 2004-12-02 David Reveman * src/cairo_gstate.c (_cairo_gstate_clip): Revert the "return early" change so that rectangular clipping works with backends that don't support clipping regions. 2004-11-29 Carl Worth * COPYING: Fix typo: LPGL->LGPL. * src/cairo_ps_surface.c (cairo_ps_surface_create): Remove unintentional copyright statement from user-generated output image. 2004-11-23 Carl Worth * test/Makefile.am (XFAIL_TESTS): Note that text_cache_crash is expected to fail. * test/text_cache_crash.c (draw): Add test to demonstrate bug when item is too big for cache. * src/cairo_cache.c (_cache_sane_state): Really remove that refcount assertion this time. * test/text_cache_crash.c: Add note that bug has been fixed.

(_cache_sane_state): Remove refcount assertion as it it false during the cairo_cache_destroy. (_cache_sane_state): #include moved up to cairoint.h (_entry_destroy): Fix bug in assertion (used_memory >= entry->memory), not >. (_cairo_cache_destroy): Fix timing of refcount decrement so that the destroy function actually works. 2004-11-14 Carl Worth * src/cairo_gstate.c (_cairo_gstate_select_font): Don't destroy a NULL font. 2004-11-13 Carl Worth * src/cairo_gstate.c (_cairo_gstate_select_font): Unconditionally destroy the old font, (otherwise, if the same font was selected twice in a row, a reference was lost to it, leading to assertion failures). 2004-11-12 Stuart Parmenter * src/cairo_gdip_font.cpp: * src/cairo_gdip_surface.cpp: Added GDI+ backend to Cairo. 2004-11-12 Carl Worth * src/cairo_font.c (_font_cache_hash, _font_cache_create_entry): * src/cairo_ft_font.c (_cairo_ft_font_text_to_glyphs): Move declarations above statements to satisfy pre-C99 compilers.

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. (cairo_ft_font_face): (cairo_ft_font_pattern): Minor cleanup.

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.

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.

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.

(_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.

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.

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 ;-)
