From 0f36f55ee0e7c9bf224fabbaf31843b3868f213c Mon Sep 17 00:00:00 2001 From: Owen Taylor Date: Tue, 23 Sep 2003 23:11:59 +0000 Subject: Modules now declare a list of scripts that they cover instead of a list of Tue Sep 23 18:03:57 2003 Owen Taylor * pango/pango-engines.[ch] pango/pango-engines-private.h: Modules now declare a list of scripts that they cover instead of a list of code point ranges. 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. --- pango/pango-fontmap.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'pango/pango-fontmap.h') diff --git a/pango/pango-fontmap.h b/pango/pango-fontmap.h index ddf7d173..5fc5d78f 100644 --- a/pango/pango-fontmap.h +++ b/pango/pango-fontmap.h @@ -46,7 +46,6 @@ void pango_font_map_list_families (PangoFontMap *fontma PangoFontFamily ***families, int *n_families); - #ifdef PANGO_ENABLE_BACKEND #define PANGO_FONT_MAP_CLASS(klass) (G_TYPE_CHECK_CLASS_CAST ((klass), PANGO_TYPE_FONT_MAP, PangoFontMapClass)) @@ -76,6 +75,8 @@ struct _PangoFontMapClass PangoContext *context, const PangoFontDescription *desc, PangoLanguage *language); + + const char *shape_engine_type; /*< private >*/ @@ -86,6 +87,8 @@ struct _PangoFontMapClass void (*_pango_reserved4) (void); }; +const char *pango_font_map_get_shape_engine_type (PangoFontMap *fontmap); + #endif /* PANGO_ENABLE_BACKEND */ G_END_DECLS -- cgit v1.2.1
