It comes less than two weeks after the 1.5.14 snapshot and it really is a legitimate snapshot, (in spite of sharing this date with that of many bogus announcements). The major change in this snapshot is that the cairo-quartz backend is now officially "supported", including new API to construct a font face from a CGFontRef . Also several bug fixes have been fixed in many backends. See below for details. This is definitely a "release candidate" snapshot for cairo 1.6.0. At this point all significant items from the cairo 1.6.0 roadmap are already in this snapshot. See: http://cairographics.org/roadmap At this point, the only change we are planning to make before cairo 1.6 is to change the setting of the infamous buggy_repeat flag, (depending on what we learn from characterizing which X server/driver versions exhibit bugs). We don't anticipate any other changes unless people identify bugs. So please let us know if you find anything. We plan to release cairo 1.6 by the end of this week. Have fun with cairo! -Carl What's new in cairo 1.5.16 compared to cairo 1.5.14 =================================================== general ------- Cairo now depends on pixman 0.10.0 which was recently released. The latest pixman release can always be found alongside cairo releases at: http://cairographics.org/releases Increase the precision of color stops for gradients. This fixes a regression in gradient rendering that had been present since the 1.5.12 snapshot. paginated (all of ps, pdf, svg, and win32-printing) --------------------------------------------------- Fix assertion failure when some drawing elements are outside the page boundaries, (this bug was noticed when using Inkscape to print a drawing with landscape orientation to a portrait-oriented piece of paper). cairo-ps -------- Fix of bug causing incorrect glyph positioning. Fix handling of CAIRO_OPERATOR_SOURCE. cairo-pdf --------- More reduction of unnecessary digits of precision in PDF output. Fix handling of CAIRO_OPERATOR_SOURCE. cairo-svg --------- Fix bug in usage of libpng that was preventing cairo_mask from working with the svg backend. Fix transformation of source pattern for cairo_stroke(). cairo-win32-printing -------------------- Fix fallback resolution, (thanks again to inkscape users/developers for helping us find this one). cairo-quartz ------------ Mark the cairo-quartz backend as "supported" rather than "experimental". This means the following: * The backend will now be built by default (if possible). * We are committing that the backend-specific API (as published in cairo-quartz.h) are stable and will be supported in all future cairo 1.x releases. * We are committing that the output quality of this backend compares favorably with other cairo backends, (and that quality is ensured by good results from the cairo test suite). * We recommend that distributions build and distribute this backend when possible. Note that the cairo_quartz_image API (in cairo-quartz-image.h) is still experimental, will not build by default, (pass --enable-quartz-image to configure to build it), and may see API changes before it is marked as "supported" in a future release. Put the CAIRO_FONT_TYPE_ATSUI name back into cairo-deprecated.h. Without this, the cairo 1.5.14 snapshot broke all builds for applications using the C++ cairomm bindings (and perhaps others) which have the CAIRO_FONT_TYPE_ATSUI name in their header files. This breakage happened even for applications not using cairo-quartz at all. Note: Even though the CAIRO_FONT_TYPE_ATSUI name is provided to avoid this build breakage, we still recommend that bindings and applications move to the new, and more accurate, CAIRO_FONT_TYPE_QUARTZ name. Replace the implementation of cairo-quartz-font to use CGFont instead of ATSUI. The CGFont API is a better fit than ATSUI, and this new implementation is also more correct than the old one as well. This also adds the following new API call: cairo_public cairo_font_face_t * cairo_quartz_font_face_create_for_cgfont (CGFontRef font); The previous cairo_quartz_font_face_create_for_atsu_font_id function continues to exist and is part of the supported API going forward. (However, the old name of that same function, which was cairo_atsui_font_face_create_for_atsu_font_id is officially deprecated. Any source code using the old name should be updated to use the new name.) Fix transformation of source pattern for cairo_stroke(). cairo-win32 ----------- Avoid crash in create_similar is cairo_win32_surface_create fails.
