+ Subject: cairo release 1.8.0 now available
+
+ A new cairo release 1.8.0 is now available from:
+
+ http://cairographics.org/releases/cairo-1.8.0.tar.gz
+
+ which can be verified with:
+
+ http://cairographics.org/releases/cairo-1.8.0.tar.gz.sha1
+ 8a689ca47c24216f37bb8cabae21ff08a7f47899 cairo-1.8.0.tar.gz
+
+ http://cairographics.org/releases/cairo-1.8.0.tar.gz.sha1.asc
+ (signed by Carl Worth)
+
+ Additionally, a git clone of the source tree:
+
+ git clone git://git.cairographics.org/git/cairo
+
+ will include a signed 1.8.0 tag which points to a commit named:
+ 6b3aa86b1c5b2fce3e56b43142c4ec2664a37032
+
+ which can be verified with:
+ git verify-tag 1.8.0
+
+ and can be checked out with a command such as:
+ git checkout -b build 1.8.0
+
+ The cairo community is happy (and relieved) to announce the 1.8.0
+ release of the cairo graphics library. This is a major update to
+ cairo, with new features and enhanced functionality which maintains
+ compatibility for applications written using any previous major cairo
+ release, (1.6, 1.4, 1.2, or 1.0). We recommend that anybody using a
+ previous version of cairo upgrade to cairo 1.8.0.
+
+ The dominant theme of this release is improvements to cairo's ability
+ to handle text. The highlights include a new "user fonts" feature as
+ well as a new cairo_show_text_glyphs API which allows glyphs to be
+ embedded in PDF output along with their original text, (for searching,
+ selection, and copy-and-paste). Another major feature is a revamp of
+ cairo's build system making it much easier to build cairo on various
+ platforms.
+
+ See below for more details.
+
+ User fonts
+ ----------
+ This new API allows the user of cairo API to provide drawings for
+ glyphs in a font. A common use for this is implementing fonts in
+ non-standard formats, like SVG fonts and Flash fonts. This API can
+ also be used by applications to provide custom glyph shapes for fonts
+ while still getting access to cairo's glyph caches. See
+ test/user-font.c and test/user-font-proxy.c for usage examples. This
+ is based on early work by Kristian Høgsberg. Thanks Kristian!
+
+ This new API consists of the following functions (and corresponding
+ _get functions):
+
+ cairo_user_font_face_create
+
+ cairo_user_font_face_set_init_func
+ cairo_user_font_face_set_render_glyph_func
+ cairo_user_font_face_set_text_to_glyphs_func
+ cairo_user_font_face_set_unicode_to_glyph_func
+
+ An additional, new API is
+
+ cairo_scaled_font_text_to_glyphs
+
+ We were previously reluctant to provide this function as
+ text-to-glyphs support in cairo was limited to "toy" font
+ functionality, not really interesting for real-world text
+ processing. However, with user fonts landing, this API is needed to
+ expose full access to how user fonts convert text to glyphs. This is
+ expected to be used by text toolkits like Pango, as well as "proxy"
+ user-font implementations.
+
+ cairo_show_text_glyphs
+ ----------------------
+ This new API allows the caller of cairo to provide text data
+ corresponding to glyphs being drawn. The PDF backend implements this
+ new API so that complex text can be copied out of cairo's PDF output
+ correctly and reliably, (assuming the user of cairo calls
+ cairo_show_text_glyphs). The cairo_show_text_glyphs API is definitely
+ the most daunting API to debut in cairo. It is anticipated that pango
+ (and similar high-level text libraries) will be the primary users of
+ this API. In fact, pango 1.22 already uses cairo_show_text_glyphs.
+ Behdad was the architect and implementor of this effort. Thanks,
+ Behdad!
+
+ The cairo_show_text_glyphs API includes the following new functions:
+
+ cairo_show_text_glyphs
+
+ cairo_glyph_allocate
+ cairo_glyph_free
+
+ cairo_text_cluster_allocate
+ cairo_text_cluster_free
+
+ cairo_surface_has_show_text_glyphs
+
+ Build system revamp
+ -------------------
+ The primary goal of the revamp is to make the build system less
+ fragile, (particularly for non-Linux platforms). For example, now
+ people building on win32 will no longer need to maintain a
+ platform-specific list of files to be built. See the new README.win32
+ for details. Also, the .so file will now be installed with a different
+ naming scheme, (for example, 1.7.6 will install with a .10800
+ suffix). Many thanks to Behdad and his small army of helpers!
+
+ Assorted API additions
+ ----------------------
+ For API completeness, several missing "getter" functions were added:
+
+ cairo_scaled_font_get_scale_matrix
+
+ cairo_surface_get_fallback_resolution
+
+ cairo_toy_font_face_create
+ cairo_toy_font_face_get_family
+ cairo_toy_font_face_get_slant
+ cairo_toy_font_face_get_weight
+
+ The new cairo_toy_font_face functions provide access to functionality
+ and settings provided by cairo_select_font_face(). Thanks Behdad!
+
+ cairo-ps/cairo-pdf: More efficient output
+ -----------------------------------------
+ Adrian Johnson has been busy fixing all kinds of bugs in PS and PDF
+ backends, as well making them generate much more compact output by
+ avoiding things like re-emitting the color or linestyle on every
+ drawing operation. Thanks Adrian!
+
+ cairo-xlib: dithering
+ ---------------------
+ Dithering: Cairo now does simple dithering when rendering to legacy X
+ servers. This is most visible with 8-bit visuals. Thanks Behdad!
+
+ cairo-xlib: Avoid rendering glyphs out of surface bounds
+ --------------------------------------------------------
+ This seemingly harmless optimization exposed a bug in OpenOffice.org 3
+ versions where OO.o was passing bogus surface extents to cairo,
+ resulting in no text rendered in OO.o. Please contact your
+ distribution's OO.o maintainers if you see this bug and point them to
+ the following URL:
+
+ https://bugs.freedesktop.org/show_bug.cgi?id=16209
+
+ cairo-xlib: Improved performance with X server without Render
+ -------------------------------------------------------------
+ Cairo now performs better on remote X servers that lack the Render
+ extension by being smarter about using X core protocol facilities
+ instead of falling back to doing all rendering on the client side.
+
+ cairo-ft: respecting FC_FT_FACE
+ -------------------------------
+ Previously it was impossible to instruct cairo to do emboldening on a
+ font face object created from an FT_Face. Cairo now respects and uses
+ the FC_FT_FACE fontconfig pattern element, so emboldening can be
+ achieved by using cairo_ft_font_face_create_for_pattern() and a
+ carefully crafted pattern using FC_FT_FACE and FC_EMBOLDEN. Thanks
+ Behdad!
+
+ cairo-directfb: backend improvements
+ ------------------------------------
+ The directfb backend, though still unsupported, has seen a good deal
+ of improvements. Thanks Vlad!
+
+ Bug fixing and optimizations
+ ----------------------------
+ xlib: Faster bookkeeping (Karl Tomlinson)
+ https://bugzilla.mozilla.org/show_bug.cgi?id=453199#c5
+
+ PS: Fix gradients with non-constant alpha (Chris Wilson)
+
+ Fix deadlock in user-font code (Richard Hughes and Behdad Esfahbod)
+ http://bugs.freedesktop.org/show_bug.cgi?id=16819
+
+ Countless other bugs have been fixed and optimizations made, many of
+ them thanks to Chris Wilson. Thanks Chris and others!
+
+ Note also that the code that had been in cairo 1.7.x calling into
+ freetype's optional lcd_filter function was removed from cairo before
+ the 1.8.0 release. We do expect this code to come back in some form in
+ the future.
