So, update your app, benefit from more optimizations (in this case, line extents caching)!
* Bug 135683 – Cache glyphstring extentsBehdad Esfahbod2006-12-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 2006-12-04 Behdad Esfahbod <behdad@gnome.org> Bug 135683 – Cache glyphstring extents * pango/pango-layout.c (pango_layout_get_lines), (pango_layout_get_line), (pango_layout_line_leaked), (pango_layout_line_get_extents), (pango_layout_line_new), (pango_layout_iter_get_run), (pango_layout_iter_get_line): Cache line extents. Line extents are cached only if the user doesn't have a pointer to the line or any of its runs. Functions that give away such pointers mark the line as "leak"ed. * pango/pango-layout.c (pango_layout_index_to_line_and_extents), (pango_layout_xy_to_index), (pango_layout_index_to_pos): Use _pango_layout_iter_get_line() which is like pango_layout_iter_get_line() but doesn't leak the line. * pango/pango-layout-private.h: Add pango_layout_iter_get_line() duplicate _pango_layout_iter_get_line_readonly() that doesn't leak the line. * pango/pango-renderer.c (pango_renderer_draw_layout): Use _pango_layout_iter_get_line_readonly().

| | | | | | | | | 2006-11-30 Behdad Esfahbod <behdad@gnome.org> * pango/pango-renderer.c (pango_renderer_draw_layout_line): Don't call into pango_glyph_string_extents() if we don't need anything out of it! (Ok, that function returns immediately in that case, but still, avoiding the call overhead.)

| | | | | | | | | | | | | | | | | 2006-09-11 Behdad Esfahbod <behdad@gnome.org> Bug 347146 – underline/overstrike spaces * pango/pango-renderer.c (add_underline), (add_strikethrough), (pango_renderer_draw_layout_line): Use logical extents for x and width of underline/strikethrough, such that trailing spaces are correctly handled. * pango/pango-layout.c (pango_layout_run_get_extents): Use logical rect for underline/strikethrough, and reflect that in run ink extents. * pango/pango-layout.c (pango_layout_line_get_extents): Don't let runs with empty ink extents affect total ink extents.

| | | | | | | | | | | | | | | | | 2006-06-06 Behdad Esfahbod <behdad@gnome.org> Followup on previous change. * pango/pango-renderer.c: Note that pango_renderer_draw_rectangle and pango_renderer_draw_error_underline should be called with active renderer. * pango/pangocairo-render.c (pango_cairo_renderer_draw_glyphs), (_pango_cairo_do_glyph_string), (_pango_cairo_do_layout_line), (_pango_cairo_do_layout): Remove excess cairo_save/restore() calls. * pango/pangocairo-render.c (_pango_cairo_do_error_underline): Don't go through renderer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
