* pangocairo-render: Make a local constTimm Bäder2020-06-101-1/+1
| | | | | | | | Avoiding this warning: ../pango/pangocairo-render.c:506:19: warning: assigning to 'char *' from 'const char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers] for (row = 0, p = name; row < rows; row++) ^ ~~~~
* renderer: Implement overlinesMatthias Clasen2019-10-311-0/+2
| | | | | | | Implement overlines in PangoRenderer. This adds a new render part, and mirrors the machinery we have for underlines and strikethrough.
* cairo: Render visible space differentlyMatthias Clasen2019-07-251-0/+77
| | | | | | | | | Instead of a [SPC] hex box, just render a centered dot, as is commonly used to indicate space. Also render synthetic glyphs for tabs and newlines. This makes single-paragraph mode prettier.
* cairo: Better hex boxes for ignorablesMatthias Clasen2019-07-251-6/+20
| | | | | | For ignorable characters such as U+00AD, Soft Hyphen, render a hex box with their 'nickname', which is a 2-6 character short form such as SHY.
* Documentation tweaksMatthias Clasen2019-07-131-2/+2

* cairo: Don't render hex box for spaceMatthias Clasen2019-07-071-1/+6
| | | | | | Even if a font has no space glyph, we don't want to render a hex box for it, since just rendering nothing does a decent approximation of space.
* Header cleanupMatthias Clasen2019-07-041-0/+1
| | | | | | | Abolish the PANGO_ENABLE_BACKEND and PANGO_ENABLE_ENGINE defines. All backend-only apis are moved into private headers, all apis that were engine-only are marked as deprecated, since engines are.
* docs: Use Markdown instead of DocbookEmmanuele Bassi2017-08-091-9/+9
| | | | | | | The example code is not correctly escaped, and gtk-doc has become slightly more strict. This is a good chance to port this bit of the API reference to Markdown, and avoid all issues in a future without inlined XML.
* trivial: fix a typoMatthias Clasen2017-06-301-1/+1
| | | | s/bytess/bytes/ in a warning.
* attributes: Make alpha work without colorMatthias Clasen2017-04-081-8/+29
| | | | | | | Improve the behavior of the cairo renderer to take alpha into account even if no color specified. https://bugzilla.gnome.org/show_bug.cgi?id=773767
* Add alpha support to PangoCairoRendererMatthias Clasen2015-08-111-4/+9
| | | | | | Make PangoCairoRenderer use cairo_set_source_rgba() to apply colors with alpha. Note that this means we are only using the alpha if the corresponding color has been set.
