* Improve letterspacing with marksfix-letterspacingMatthias Clasen2021-03-211-1/+10
| | | | | | | | harfbuzz puts marks into their own clusters, so we need to work a little harder to keep non-spacing marks placed over their base character. Fixes: #541
* docs: Tweak glyph item docsMatthias Clasen2021-03-111-41/+49
| | | | Add summaries, convert markup, etc.
* glyph-item: Allocate attr iterator on the stackTimm Bäder2020-06-081-9/+11
|
* glyph iter: Adjust assertionsMatthias Clasen2019-07-171-2/+2
| | | | | | With the inserted hyphens we end up in a situation where we have start_char == end_char at the end of an item. It seems to be otherwise harmless.
* Protect against bugs in HarfBuzz's (non-)monotone cluster valuesBehdad Esfahbod2015-09-011-4/+4
| | | | | | "Fixes" https://bugzilla.gnome.org/show_bug.cgi?id=541608 Real fix went to HarfBuzz.

* Fix pango_glyph_item_iter_prev() around last clusterBehdad Esfahbod2015-08-081-4/+4
| | | | | | It was combining the last two clusters. Ouch! Test added already. Passes now.

* PangoGlyphItem: Better treatment of ellipsized runsMatthias Clasen2014-09-031-2/+6
| | | | | | | | | When we reapply non-shape attributes, we must take care to not add any attributes that start in the middle of an ellipsized run, or we end up with a blue, underlined ellipsis if there is a link anywhere inside the ellipsized text. https://bugzilla.gnome.org/show_bug.cgi?id=735732

* Handle NUL in text in places that g_utf8_strlen () was usedBehdad Esfahbod2009-07-151-4/+4
| | | | | | | | | | While pango-layout doesn't allow NUL in text, the lower level API should handle it correctly. We were using g_utf8_strlen() in a number of places. This is problematic since that function stops processing at NUL even if length>1. We now use an internal pango_utf8_strlen() instead. Inspired by: Bug 588678 – pango crash: install a new theme from gnome-appearance-properties
