* shape: Bring back careful rounding codebring-back-better-roundingMatthias Clasen2021-06-271-4/+73
| | | | | | | | | | | | | | | | When we added the round-glyph-positions option in c43da2d3 and b5634799, we lost some code that was careful to round in device coordinates. The reason we lost it is that the rounding needs fontconfig- specific data that is only available in the backend, and the rounding now happens in the frontend. Bringing it back is annoying, since we've run out of vfunc slots to get info from the backend. This commit works around that limitation in a hacky way. Fixes: #562
* introspection: Stop using allow-noneMatthias Clasen2021-05-191-2/+2
| | | | | The allow-none annotation has been deprecated for a long time already. Instead use optional and nullable everywhere.
* docs: Tweak shaping docsMatthias Clasen2021-03-111-42/+36
| | | | Add summaries, convert markup, etc.
* Amend the shaping api docsshape-docsMatthias Clasen2020-11-071-4/+19
| | | | | | | Discuss problems with extra_attr indices in the docs for pango_shape() and friends. See: #511
* Add a pango_shape variant that takes flagsMatthias Clasen2019-08-031-22/+71
| | | | | The only flag currently defined affects whether glyph positions are rounded or not.
* Remove unused remnants of shape engineKhaled Hosny2019-07-191-1/+0

* Rename _pango_fc_shapeMatthias Clasen2019-07-181-5/+5
| | | | It is all harfbuzz now, so call it pango_hb_shape.
* Switch to using harfbuzz for shapingMatthias Clasen2019-07-181-61/+73
| | | | | | Drop internal shape engine uses and call _pango_fc_shape directly. This makes us use harfbuzz for shaping, on all backends.

| | | | Patch from Rafał Mużyło.
* Add pango_shape_full()Behdad Esfahbod2012-09-261-5/+58
| | | | | | | | | | | | | | | | Variant of pango_shape() that takes the full paragraph text as input. This is then passed in entirety to HarfBuzz, which would allow certain cross-run interactions (in Arabic for example). When combined with upcoming HarfBuzz 0.9.5+, this fixes: Red Hat Bug 858736 - [Spanish] Stray dotted circle rendered https://bugzilla.redhat.com/show_bug.cgi?id=858736 and partially: Bug 313181 - color changes break arabic shaping https://bugzilla.gnome.org/show_bug.cgi?id=313181

* Bug 596614 - Pango application receives SIGSEGV on pasting text with U+202EBehdad Esfahbod2009-11-171-3/+31
| | | | | Fixed all modules to reverse glyphs if run is rtl. Except for Hangul module. Fixed pango_shape() to detect that, warn, and reverse.

It means, no rendering should be performed. The backends however, still return 0 if a glyph is not found.

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.

Use this to handle underlining for PangoLayout. * examples/viewer.c (reload_font): Make paragraphs global to save the complexity of passing it around all over the place. * pango/pango-layout.[ch] (pango_layout_context_changed): Add a function to reset the layout on changes to the layout's context. * pango/pangox.c (pango_x_make_matching_xlfd): Prefer bitmap to scaleable if the discrepancy is < 1 pixel. (Probably not the ideal criterion.) * pango/pangox.c (pango_x_font_map_for_display): Fix resolution computation error. * pango/pango-layout.c (pango_layout_check_lines): Handle text with embedded newlines. * pango/pangox.c (pango_x_render_layout): Fix y to refer to the top of the layout, not the baseline of the first line. * pango/pango-layout.c (process_item): Don't wrap if width is set to -1. * Makefile.am configure.in **/*.[ch]: move libpango/ directory and fix all headers to install under include/pango/
