news 28 Posted June 16, 2009 A new cairo release 1.8.8 is now available from: http://cairographics.org/releases/cairo-1.8.8.tar.gz'>http://cairographics.org/releases/cairo-1.8.8.tar.gz which can be verified with: http://cairographics.org/releases/cairo-1.8.8.tar.gz.sha1 e4b8b219427d1ca3dc95f5f44914dce1ae0c3766 cairo-1.8.8.tar.gz http://cairographics.org/releases/cairo-1.8.8.tar.gz.sha1.asc (signed by Chris Wilson) Additionally, a git clone of the source tree: git clone git://git.cairographics.org/git/cairo will include a signed 1.8.8 tag which points to a commit named: 7dd89ff7a1e04930045d9726f5f21330f54d3f24 which can be verified with: git verify-tag 1.8.8 and can be checked out with a command such as: git checkout -b build 1.8.8 The cairo community is pleased to announce the 1.8.8 release of the cairo graphics library. This is the fourth update to cairo's stable 1.8 series and contains a small number of bug fixes (in particular a few corrections to the documentation and a few fixes in the FreeType font backend). This is being released just over six months after cairo 1.8.6. We recommend that everyone using cairo upgrade to 1.8.8. -Chris Build fixes ----------- There were reports of incompatibilities with the autotools bundled in with the 1.8.6 tarball. This release has been built with automake-1.10.2 and autoconf-2.63. The configure check for FreeType has been improved: typo in check for version of freetype in configure script https://bugs.freedesktop.org/show_bug.cgi?id=19283 Compilation on 64-bit MacOS/X fixes: Cannot build cairo_quartz_font_face_create_for_atsu_font_id on 64-bit Mac OS X https://bugs.freedesktop.org/show_bug.cgi?id=15702 Bug fixes --------- Uninitialised status return within _cairo_clip_intersect_mask(). This caused random crashes and general mayhem as an error could be generated causing all rendering to the context to stop. Avoid transforming nearly-degenerate matrices into degenerate matrices: Painting stops in this case, using -moz-transform: scale, rotate and video https://bugzilla.mozilla.org/show_bug.cgi?id=467423 A few FreeType font handling bugs were fixed: Rendering with PANGO_GRAVITY_EAST leads to different results with image and pdf https://bugs.freedesktop.org/show_bug.cgi?id=21985 Don't call FT_Done_Face() on faces we did not create zombie ft_font_face / ft_unscaled_font mutual referencing problems http://bugs.freedesktop.org/show_bug.cgi?id=21706 Ensure win32 font backend sets the return value to -1 (indicating the absent glyph) if the font index lookup for the unicode character fails. And similarly fix a bug where a fatal error was raised for an invalid glyph. cairo_scaled_font_glyph_extents breaks with invalid glyph id http://bugs.freedesktop.org/show_bug.cgi?id=20255 Various improvements to the documentation, reported by Truc Troung: https://bugs.freedesktop.org/show_bug.cgi?id=20095 https://bugs.freedesktop.org/show_bug.cgi?id=20154 https://bugs.freedesktop.org/show_bug.cgi?id=20180 https://bugs.freedesktop.org/show_bug.cgi?id=20183 https://bugs.freedesktop.org/show_bug.cgi?id=20182 https://bugs.freedesktop.org/show_bug.cgi?id=20441 All changes from cairo 1.8.6 to 1.8.8 ------------------------------------- Adrian Johnson (1): Ensure win32 font index_to_ucs4() sets ucs4 to -1 if lookup fails Behdad Esfahbod (1): [ft] Fix vertical advance metrics of bitmap fonts (#21985) Chris Wilson (25): Increment version to 1.8.7 after the 1.8.6 release.

Currently supported output targets include the X Window System, quartz, win32, and image buffers, as well as PDF, PostScript, and SVG file output. Experimental backends include OpenGL (through glitz), XCB, BeOS, OS/2, and DirectFB. Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (for example, through the X Render Extension). The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo include stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.). Cairo has been designed to let you draw anything you want in a modern 2D graphical user interface. At the same time, the cairo API has been designed to be as fun and easy to learn as possible. If you're not having fun while programming with cairo, then we have failed somewhere---let us know and we'll try to fix it next time around. Cairo is free software and is available to be redistributed and/or modified under the terms of either the GNU Lesser General Public License (LGPL) version 2.1 or the Mozilla Public License (MPL) version 1.1.
