A simple justification algorithm is implemented + that tries to justify by expanding spaces in the line, and if none + found, by adjust letter spacing. [Based on patch by Mathias + Hasselmann] + +- The pango_script_get_sample_language() function is modified to use + the value of environment variables PANGO_LANGUAGE or LANGUAGE + (checked in that order) to make guess better languages for scripts. + The env var should be a list of language tags, like "en:fa" for + example where in effect makes Pango choose Persian (fa) fonts + instead of Arabic (ar) fonts when a run of text in the Arabic script + is found in an otherwise non-Arabic layout. + + This trick is also useful for East Asian languages. For example a + Japanese user that cannot set her primary language to Japanese can + still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to + Japanese. + + The LANGUAGE env var is a standard gettext variable listing + languages the user wants to receive UI translated messages in. + However, since most packages don't provide separate English + translations, setting LANGUAGE="en:ja" doesn't have the intended + effect and UI messages will be shown in Japanese. For these + situations one can use LANGUAGE="en:C:ja". Pango skips the special + language tag 'C'. + +- Simplified embedded-shape rendering with pangocairo backends do. + [Richard Hult] + +- New header file: Moved PangoLanguage APIs into its own header + pango-language.h, which is included from pango-types.h. + +- ATSUI backend now lists synthesized italic faces like other + +- Misc optimizations and fixes. + +OpenType Layout Engine Improvements: + +- Vertical glyph variants are not selected in vertical text if the + font supports them. + +- Instead of hardcoded OpenType script tag in each module, and using + Default Language System unconditionally, Pango will now find and use + the script/lang-sys pair that best matches the detected script and + language of a run of text. Moreover, it also applies the OpenType + 'locl' feature. + + These, plus the PANGO_LANGUAGE env var, give font designers and + users lots of options to provide/choose language-specific glyph + variants. + + Only basic, arabic, and syriac modules updated to take advantage of + the new support so far. + +New pango-view command line options: + + --align + --justify + --language + +Public API Changes: + +- New public pangocairo API: + + PangoCairoShapeRendererFunc + pango_cairo_context_set_shape_renderer() + pango_cairo_context_get_shape_renderer() + + These are used by the default pangocairo renderer to render shape + attributes (see examples/cairoshape.c).

This changes some public API + that was broken in the 1.15 series. The new struct is backward compatible + with the older Pango series, but not with earlier 1.15.x devel releases. + +- New Public API: + + * PangoAnalysis.flags and PANGO_ANALYSIS_FLAGS_CENTERED_BASELINE. These are + mostly only useful for the vertical text support in Pango, but language + bindings probably want to update their bindings for PangoAnalysis to + include these. + + * New PangoMatrix methods: + + pango_matrix_transform_distance() + pango_matrix_transform_point() + pango_matrix_transform_rectangle() + pango_matrix_transform_pixel_rectangle() + + The transform_rectangle methods are particularly useful when an + app/toolkit wants to know the extents of a rotated layout in device + coordinates. It will be used by Gtk+ for example, and is used by the + pango-view tool too. The _pixel_ variant takes a PangoRectangle in device + units instead of Pango units. + + * Unit conversion helpers: + + pango_units_from_double() + pango_units_to_double() + pango_extents_to_pixels() + + The first two just convert between Pango units (fixed precision) and + double floating-point numbers. The current implementations are as simple + as "(int)floor (d * PANGO_SCALE + 0.5)" and "(double)i / PANGO_SCALE", but + the idea is to have optimized versions of these that do not use the FPU in + the future. That will be appreciated by embedded devices without FPU + units. Since the functionality can be generally useful, the API is made + public. + + The pango_extents_to_pixels() function in conjunction with + pango_matrix_transform_rectangle() makes it possible to convert extents to + device space and round then, instead of having to transform rounded + user-space extents. + +- Bugs fixed in this release: + Bug 351496 – PangoAnalysis::gravity breaks binary compatibility + Bug 388702 – Crash when there's no Hangul glyph in the font. + Bug 384543 – FcFontMatch misuse + Bug 392789 – vpath build fails in basic module + Patch from J. Ali Harlow + Bug 390877 – Don't feed pango-features.h to glib-mkenums + Patch from Yevgen Muntyan + + +Overview of changes between 1.15.1 and 1.15.2 +============================================== +* Engines: + - Improved Hangul shaper engine + - Improved Indic shaper and language engines + - Require libthai >= 0.1.7 for the Thai language engine + +* Optimizations: + - Avoid some floating-point operations. Should cut the number of float + ops per expose event in pangocairo to a half. + - Cache ink and logical extents for PangoLayout + +* New Public API: + + - New, generated, public header file pango-features.h. Included by + pango.h. Currently contains the version information. In the future, + can be expanded to define which backends have been enabled, etc. + + - Public macros and functions for compile- and run-time version checking: + + PANGO_VERSION_ENCODE() + PANGO_VERSION_MAJOR + PANGO_VERSION_MINOR + PANGO_VERSION_MICRO + PANGO_VERSION + PANGO_VERSION_STRING + PANGO_VERSION_CHECK() + pango_version() + pango_version_string() + pango_version_check() + + The scheme chosen here is a mixture of approaches taken by glib and cairo. + The advantage over the glib model is that there are no public variables, + but it still gives access to a string and numerical representation of the + version number at compile- and run-time. + + The macros enable conditional compilation of code depending on newer Pango + APIs, while the runtime functions allow refusing to run against old + versions of the library. + + - New, readonly, version of methods that give read/write access to the + internals of PangoLayout: + + pango_layout_get_line_readonly() + pango_layout_get_lines_readonly() + pango_layout_iter_get_line_readonly() + pango_layout_iter_get_run_readonly() + + These should be used when you do not intend to modify the run/line, + which is most of the time the case. The only exception known to me + is Firefox that adjusts glyph widths to do justification. Most other + uses that do not write to the returned structs (or structs accessible from + them) should be ported to the new readonly API to benefit from major + optimizations (in this case, line extents caching). The list includes, + but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint, + xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp, + and various other applications/libraries: + + http://www.google.com/codesearch?hl=en&q=+pango_layout_(iter_)%3Fget_(lines%3F%7Crun)%5B%5E_%5D&start=50&sa=N + + Worth noting here is that, many uses of pango_layout_get_lines() can be + replaced by a pango_layout_get_iter() that works both more elegantly and + more efficiently. The versioning macros introduced in this release can be + used to make code use these new symbols without breaking compilation + against older Pango (though, such code compiled with the new Pango cannot + be run against an older Pango). + + - pango_language_get_default(): Note that, this does not make Pango + fallback to the default language automatically (yet), but the user can + use this function to set the default language of the locale on a context: + + pango_context_set_language (context, pango_language_get_default()); + + This essentially deprecates gtk_get_default_language(). The pango-view + tool has been updated to use this feature, so it now respects $LANG when + choosing fonts. + + - pango_color_to_string(). + +* Bugs fixed in this release: + Bug 326099 – Setting width, indentation and ellipsizing doesn't work + as I would expect + Bug 385478 – Fix tests on OPD platform + Bug 319808 – Patch to let pango support artifical italic, bold and + bold italic styles for the fonts which don't have these styles. + Patch from James Su + Bug 385321 – Worst case expansion for Sinhala + Patch from Harshula + Red Hat Bug 211574: [hi/ml/si_LK] cursor naviation is wrong when + using ZWJ (200d) + Patch from LingNing Zhang + Red Hat Bug 216424: [te_IN] pango - consonant + dependent vowel (ai) + Composed char is not rendering properly + Patch from LingNing Zhang + Bug 373856 – Wish: Function to convert a GdkColor to a string + Patch from Matthew Barnes + Red Hat Bug 216850: Issue in combination with vowels (ml_IN) + Patch from LingNing Zhang + Bug 382437 – tests/testboundaries fails + Bug 333982 – Fallback to $LANG whenever NULL PangoLanguage is used + Patch from LingNing Zhang + +Overview of changes between 1.15.0 and 1.15.1 +============================================== +* Add Thai langauage engine.

Shouldn't make + any difference whatsoever. Open a bug if it does. +* Misc small fixes. + +* Optimizations: + - Rework PangoLayout algorithms to avoid calling a recursive call to + pango_layout_get_extents(). Avoids one pango_font_get_glyph_extents() + call per glyph per layout rendering.

We are down to 1 now. + - Cache line extents. This avoids the final pango_font_get_glyph_extents() + call per glyph per layout rendering. Now we don't make any + pango_font_get_glyph_extents() calls when rendering a layout (some + conditions apply)! + - Replace PANGO_IS_RENDERER with PANGO_IS_RENDERER_FAST for most + internal uses, that is, just a NULL-check. + - Use simple, fast, casts instead of PANGO_CAIRO_*() macros where the + object cannot have reached us if it wasn't of the right type. + +* Bugs fixed in this release: + Bug 135683 – Cache glyphstring extents + Red Hat Bug 211964: [ta] Rendering issue with Tamil + Patch from LingNing Zhang + Red Hat Bug 213632: ZWJ (200d) and ZWNJ (200c) showing same output + Patch from LingNing Zhang + Bug 371388 – Add Thai langauage engine + Patch from Theppitak Karoonboonyanan + Bug 377975 – bug in _pango_glyph_item_iter_next_cluster + Bug 369670 – Checked g_free calls + +Changes that also appeared between 1.14.7 and 1.14.8 +===================================================== +* Improved thread-safety.
