Pango-1.19.0 is now available for download at: http://download.gnome.org/sources/pango/1.19/ or ftp://ftp.gtk.org/pub/pango/1.19 9db02e1e27dd0d8c9f9944c3b4578b60 pango-1.19.0.tar.bz2 32cc0b7cabce4f7e47817155fa96e519 pango-1.19.0.tar.gz This is the first development release in yet another exciting cycle in Pango development, leading to Pango-1.20.0, which will be released just in time for GNOME-2.22. Notes: * This is unstable development release. While it has had fairly extensive testing, there are likely bugs remaining to be found. This release should not be used in production. * Installing this version will overwrite your existing copy of Pango. If you have problems, you'll need to reinstall Pango-1.18.x * Bugs should be reported to http://bugzilla.gnome.org. About Pango =========== Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x. Pango is designed to be modular; the core Pango layout engine can be used with different font backends. There are three basic backends, with multiple options for rendering with each. - Client side fonts using the FreeType and fontconfig libraries. Rendering can be with with Cairo or Xft libraries, or directly to an in-memory buffer with no additional libraries. - Native fonts on Microsoft Windows using Uniscribe for complex-text handling. Rendering can be done via Cairo or directly using the native Win32 API. - Native fonts on MacOS X, rendering via Cairo. The integration of Pango with Cairo (http://cairographics.org) provides a complete solution with high quality text handling and graphics rendering. Dynamically loaded modules then handle text layout for particular combinations of script and font backend. Pango ships with a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported. As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text. More information about Pango is available from http://www.pango.org/. Bugs should be reported to http://bugzilla.gnome.org. Pango 1.17 depends on version 2.14.0 or newer of the GLib library and version 1.2.6 or newer of the cairo library (if the cairo backend is desired); more information about GLib and cairo can be found at http://www.gtk.org/ and http://cairographics.org/ respectively. Overview of changes between 1.18.3 and 1.19.0 ============================================== - Update list of languages to that of fontconfig-2.4.91. - Various optimizations, making rendering the same Pango layout using changing cairo matrices much faster. - Make sure all boxed type copy/free functions accept NULL as legitimate input. Previously most were g_return_[val_]if_fail()ing it. This is mostly for convenience when writing code in C. - Apply 'vkrn' GPOS feature in vertical writing. - In pangofc, set "pangoversion" in pattern passed to fontconfig, such that font configuration can condition on being driven by Pango or not. - Various optimizations and cleanups in the OpenType Layout engine, aka HarfBuzz. - Changed APIs: * All PangoAttribute constructors are changed to initialize the attribute to the range [0..MAXUINT]. The range was undefined previously. All custom attribute constructors are recommended to call the new pango_attribute_init() to do the same. * Public API chance: Mark the following types as abstract: PangoFont PangoFontFace PangoFontFamily PangoFontMap PangoFcFont PangoFcFontMap PangoContext may be marked so in the future too. * Make following macros public. Previously they were only defined for backend/engine implementations. PANGO_GLYPH_EMPTY PANGO_GLYPH_UNKNOWN_FLAG PANGO_GET_UNKNOWN_GLYPH() - New public API: * Convenience for initializing custom attributes: pango_attribute_init() * Adding boxed type for PangoGlyphItem: PANGO_TYPE_GLYPH_ITEM pango_glyph_item_copy() pango_glyph_item_get_type() * Add missing copy function for a boxed type in C: pango_layout_iter_copy() * Add missing getter: pango_layout_iter_get_layout() * Convenience for writing custom PangoRenderer's: pango_renderer_get_layout() pango_renderer_get_layout_line() * PangoFc extensions to fontconfig's pattern syntax: PANGO_FC_GRAVITY PANGO_FC_VERSION - Bugs fixed in this release: Bug 490661 – Pango Markup: Link to font_desc syntax explanation Based on patch from Chris Toshok Bug 489909 – pango_cairo_update_context() should ignore matrix translation Bug 488840 – harfbuzz: protect against ligid overflow Bug 486932 – Apply vkrn GPOS feature in vertical writing Bug 486951 – ChangeLog.pre-1-18 Bug 485621 – Get rid of freetype memory allocator in harfbuzz Bug 485566 – Cache one OpenType Buffer Bug 485559 – Boston Summit HarfBuzz optimizations Bug 481537 – compiler warning fixes Patch from Kjartan Maraas Bug 478865 – Drastically reduce number of PangoFont objects created for rotating text Bug 472924 – Mark some classes abstract Bug 472629 – Add pango_renderer_get_layout(_line) Bug 472303 – Make PANGO_GLYPH_EMPTY and PANGO_GLYPH_UNKNOWN_FLAG public Bug 471601 – Pass pango version information to fontconfig Bug 471577 – GBoxed GType for PangoGlyphItem Bug 471571 – Add pango_layout_iter_get_layout() Bug 471568 – Optimizations in _pango_cairo_update_context() Bug 469641 – Initialize attribute start/end to [0..MAXUINT] Overview of changes between 1.18.2 and 1.18.3 ============================================== - Two OpenType engine fixes. Makes Nafees Nastaliq font work great, and avoids warnings with some other fonts. - Fix minor leak in win32 backend. - Bugs fixed in this release: Bug 483600 – Leak of font family name in pango_win32_font_description_from_logfont(w) Patch from Daniel Atallah 29 October 2007 Behdad Esfahbod
