It comes 3 weeks after the 1.5.12 snapshot. This snapshot includes support for arbitrary X server visuals, (including PseudoColor), which was the final remaining cairo-specific item on the cairo 1.6 roadmap. It also includes a huge number of improvements to the cairo-quartz backend. So this is effectively a cairo 1.6 release candidate. We expect very few changes from now until 1.6 and only for specific bug fixes. See below for more about what's new in cairo 1.5.14. We do appreciate any testing and feedback you can provide. In particular, if you know of a bug in cairo 1.5.14 that you'd like to see fixed before 1.6.0 and that bug isn't exercised by the cairo test suite, then please make loud noises on the cairo mailing list so that we know about it. Have fun with cairo! -Carl Changes from cairo 1.5.12 to 1.5.14 =================================== API Change ---------- Rename ATSUI font backend to Quartz font backend. This affects the following usage: --enable-atsui -> --enable-quartz-font CAIRO_HAS_ATSUI_FONT -> CAIRO_HAS_QUARTZ_FONT CAIRO_FONT_TYPE_ATSUI -> CAIRO_FONT_TYPE_QUARTZ cairo_atsui_font_face_create_for_atsu_font_id -> cairo_quartz_font_font_create_for_atsu_font_id This API change is justified by the cairo-quartz backend still be marked as "experimental" rather than "supported", (though this is one step toward making the change to "supported" before 1.6). Cairo will still provide ABI compatibility with the old symbol name, however. paginated (all of ps, pdf, svg, and win32-printing) --------------------------------------------------- Optimize by not analyzing an image surface for transparency more than once, (previously all images were analyzed twice). cairo-ps and cairo-pdf ---------------------- Avoiding emitting a matrix into the stroke output when unnecessary, (making output size more efficient). Reduce rounding error of path shapes by factoring large scale factors out of the path matrix, (ensuring that a fixed-number of printed digits for path coordinates contains as much information as possible). Reduce excess digits for text position coordinates. This makes the output file size much smaller without making the result any less correct. cairo-ps -------- Eliminate bug causing extraneous text repetition on Linux PostScript output in some cases. See: Mozilla Bug 419917 – Printed page contents are reflected inside bordered tables (Linux-only) https://bugzilla.mozilla.org/show_bug.cgi?id=419917 Optimize output when EXTEND_PAD is used. cairo-pdf --------- Fix to not use fill-stroke operator with transparent fill, (else PDF output doesn't match the cairo-defined correct result). See: https://bugs.launchpad.net/inkscape/+bug/202096 cairo-svg --------- Fix stroke of path with a non-solid-color source pattern: http://bugs.freedesktop.org/show_bug.cgi?id=14556 cairo-quartz ------------ Fix text rendering with gradient or image source pattern. Handling antialiasing correctly for cairo_stroke(), cairo_clip(), and cairo_show_text()/cairo_show_glyphs(). Correctly handle gradients with non-identity transformations: Fixes http://bugs.freedesktop.org/show_bug.cgi?id=14248 Add native implementation of REPEAT and REFLECT extend modes for gradients. Fix implementation for the "unbounded" operators, (CAIRO_OPERATOR_OUT, _IN, _DEST_IN, and _DEST_ATOP). Correctly handle endiannees in multi-architecture compiles on Mac OS X. Avoid behavior which would cause Core Graphics to print warnings to the console in some cases. cairo-win32 ----------- Fix handling of miter limit. cairo-win32-printing -------------------- Fix to not use a 1bpp temporary surface in some cases while printing, (so grayscale data is preserved rather than just becoming black and white). cairo-xlib ---------- Add support for rendering to arbitrary TrueColor X server visuals. This fixes at least the following bugs: cairo doesn't support 8-bit truecolor visuals https://bugs.freedesktop.org/show_bug.cgi?id=7735 cairo doesn't support 655 xlib format https://bugs.freedesktop.org/show_bug.cgi?id=9719 Add support for rendering to 8-bit PseudoColor X server visuals. This fixes the following bug: Cairo doesn't support 8-bit pseudocolor visuals https://bugs.freedesktop.org/show_bug.cgi?id=4945 Unresolved issues (must be fixed before cairo 1.6) -------------------------------------------------- XXX: Need to decide if cairo_image_surface_create_for_data should be documented and tested as supporting an image with a negative stride. Also need to decide the correct return value for cairo_format_stride_for_width in case of any error.
