* Drop cairo metrics implementationMatthias Clasen2019-08-121-2/+0
| | | | We can use the hb-based implementation in pangofc-font.c.
* Decorate the symbols in the headers with version macrosChun-wei Fan2016-06-291-0/+1
| | | | | | | From the last commit, decorate all the symbols with the version macros. Also add the version macros in the docs. https://bugzilla.gnome.org/show_bug.cgi?id=767587

* Finish the 'glyph 0' work of this morning: PANGO_GLYPH_NULL that IBehdad Esfahbod2006-02-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Use PANGO_GLYPH_UNKNOWN_FLAG for all backends to mark unknown flags. There's no need for pango_font_get_unknown_glyph() anymore, since all backends know how to handle PANGO_GLYPH_UNKNOWN_FLAG gracefully. We may add that in the future however.
