| | | | | | | | | | | | 2006-02-21 Behdad Esfahbod <behdad@gnome.org> Bug 331723 – shapers should not crash on failures * modules/*/*-fc.c: Return instead of g_return_if_fail when face == NULL. * pango/pango-engine.h (PangoEngineShape): Document that a shaper should return an empty glyph string on failure.

* Finish the 'glyph 0' work of this morning: PANGO_GLYPH_NULL that IBehdad Esfahbod2006-02-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2006-02-02 Behdad Esfahbod <behdad@gnome.org> Finish the 'glyph 0' work of this morning: PANGO_GLYPH_NULL that I introduced is renamed to PANGO_GLYPH_EMPTY. It means, no rendering should be performed. The backends however, still return 0 if a glyph is not found. The modules then are free to replace this 0 glyph with an unknown character. * modules/arabic/arabic-fc.c, modules/basic/basic-atsui.c, modules/basic/basic-fc.c, modules/basic/basic-win32.c, modules/basic/basic-x.c, modules/hangul/hangul-fc.c, modules/hebrew/hebrew-fc.c, modules/indic/indic-fc.c, modules/khmer/khmer-fc.c, modules/syriac/syriac-fc.c, modules/thai/thai-fc.c, modules/tibetan/tibetan-fc.c, pango/pangox.c, pango/pangowin32.c: Adapt to above change. Backends return 0 if glyph not found. * pango/fonts.c (pango_font_get_glyph_extents): If font is not usable (!PANGO_IS_FONT (font)), return the generic UNKNOWN_GLYPH metrics. This is used when your backends are misconfigured and you don't find *any* font at all. * pango/pango-engince.c: Add unknown glyphs in fallback shaper, instead of empty glyphs. * pango/shape.c: Call the fall-back shaper if shaper fails, instead of generating a dummy glyph string ourselves. * pango/pango-layout.c (imposed_shape, shape_tab): Use PANGO_GLYPH_EMPTY instead of glyph 0. * pango/pango-renderer.c (pango_renderer_draw_glyph): No-op on PANGO_GLYPH_EMPTY instead of glyph 0. * pango/pangocairo-atsuifont.c, pango/pangocairo-win32font.c, pango/pangocairo-fcfont.c, pango/pangocairo-font.c, pango/pangocairo-private.h: install_font returns a boolean now. * pango/pangocairo-render.c, pango/pangoxft-render.c: Handle font and hex-box failures more gracefully by drawing a generic unknown-box glyph. * pango/pangoft2.c, pango/pangoft2-render.c: Draw the generic unknown-box glyph here too. For unknown glyphs though, if the font is TTF (FT_IS_SFNT), use the zero-indexed glyph, otherwise, draw a box of proper size.

Also, there is now a ->covers() virtual function that allows a module to decide live whether the font covers a particular codepoint; remove old get_coverage() method. * pango/pango-fontset.[ch]: Add a foreach() function to iterate over all the fonts in a fontset (with a true return stopping iteration). * pango/pango-context.c: Complete rewrite using script-run information to improve language tags. Switch to an approach where we handle one run at a time rather than computing information for each character individually then later breaking the result into runs. * pango/pango-fontset.[ch]: Switch over to using pango-impl-utils.h. * modules/basic/basic-x.c pango/pangox-fontmap.c: Adapt to the change from get_coverage => covers. * pango/pango-modules.h pango/modules.c: Switch PangoMap over to being based on script rather than being based on codepoint. Remove the no longer needed pango_map_get_entry(). * pango/modules.c: Handle new script-based modules. * pango/pango-fc-fontmap.c pango/pango-win32-fontmap.c pango/pang-fontmap.[ch]: Add a shape_engine_type field to PangoFontmapClass, pango_font_map_get_shape_engine_type(); this allows generic code to find a shaper for a particular fontmap. * pango/pango-script.[ch]: Add pango_script_get_sample_language(), pango_language_includes_script(); functions for determining the relationship between scripts and language. * tools/gen-script-for-lang.c: Modify to spit out a useful table. * pango/pango-script-lang-table.h: Version of table generated from current fontconfig data. * pango/pangox.c: Remove complicated code to compute coverages; no longer useful now that we just have the basic shaper as a legacy thing. * modules/*/*.c: Adapt to identifying shape engines by language range. * modules/thai/thai-fc.c modules/thai/thai-shaper.[ch]: Remove now unused "has_glyph" function and XTIS support. * modules/thai/thai-fc.c: Handle non-Thai characters as well, since the Thai module now gets spaces, punctuation, and so forth.
