* Make missing space smallersmaller-spaceMatthias Clasen2021-12-221-1/+1
| | | | | | | The Microsoft paper I was citing actually recommends 1/4 em for ASCII space. Make it so... Update affected tests.
* Use a better size for missing spaceMatthias Clasen2021-12-211-39/+4
| | | | | | | | | | Follow the Microsoft Typography recommendations from https://docs.microsoft.com/en-us/typography/develop/character-design-standards/whitespace and use half of an em for missing space. Update affected tests. Fixes: #647
* cairo: Work harder to measure spacemore-space-tweaksMatthias Clasen2021-12-171-3/+21
| | | | | | | | | | | When coming up with a width for a missing space, we were just measuring the hex digits. But in subsetted fonts, such as the ones we use for ci, hex digits might well be missing. Take that into account and still provide some nonzero width for space. Update affected tests.
* Calculate hinted font height based on the hinted extentsSebastian Keller2021-11-221-2/+2
| | | | | | | | | | | | | The previous code was calculating the rounded up version of the difference between the unhinted ascender and uninted descender. This however would only result in the correct height if both unhinted extentss together only differ by less then an a Pango unit from their hinted counterparts. Otherwise the resulting height would be 1 unit too short. Fix this by using the difference between the hinted extents as height. Fixes: https://gitlab.gnome.org/GNOME/pango/-/issues/626
* Introduce and use FLOOR and CEIL macros in Pango unitsSebastian Keller2021-11-221-4/+4
| | | | | | | This replaces the code that was trying to implement those via the ROUND macro. This avoids a potential issue with values that already were on whole units being rounded up to the next whole unit in the code that was implementing CEIL this way.
* Make logical glyph extents betterMatthias Clasen2021-10-311-0/+2
| | | | | For east and west gravity, the logical glyph extents were still misaligned with the ink extents.
* cairo: Small fixupglyph-extents-fixesMatthias Clasen2021-10-301-1/+1
| | | | | | cf_priv->scaled_font is initialized on demand, it may be NULL. So better call the getter. This was showing up as failure in the asan test in ci.
* Use harfbuzz metrics for cairo fontsMatthias Clasen2021-10-301-14/+37
| | | | | Without this, we end up with differences in metrics of empty runs.
* cairo: Produce meaningful logical glyph extentsMatthias Clasen2021-10-301-11/+28
| | | | | Depending on gravity, our logical glyph extents were empty and mis-aligned. Fix that.
* Revert "Use harfbuzz metrics for cairo fonts"Matthias Clasen2021-10-271-22/+21
| | | | | | This broke glyph extents with gravity north or west. This reverts commit 20ec670e124e4461075a2967faa29603d25106cc.
* Use harfbuzz metrics for cairo fontsMatthias Clasen2021-10-191-21/+22
| | | | | | | Without this, we end up with differences in metrics of empty runs. Fixes: #421
* docs: Reduce redundancydocs-cleanupsMatthias Clasen2021-05-201-2/+2
| | | | | | Remove a boatload of "or %NULL" from nullable parameters and return values. gi-docgen generates suitable text from the annotation that we don't need to duplicate.
* docs: Port PangoCairo apis to the new doc formatMatthias Clasen2021-03-111-7/+7
| | | | | | Replace gtk-doc'isms and use gi-docgen links instead. Cross-gir links are still an open issue.
* Fix some annotationsRico Tzschichholz2020-06-081-1/+1
|
* Revert "Drop cairo metrics implementation"Khaled Hosny2019-08-141-0/+194
| | | | | | This reverts commit c5d86c368128bb9a0be913829da79649fb81f486. Closes #409
* Drop cairo metrics implementationMatthias Clasen2019-08-121-194/+0
| | | | We can use the hb-based implementation in pangofc-font.c.
* cairo: Render visible space differentlyMatthias Clasen2019-07-251-3/+3
| | | | | | | | | 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 Clasen2019-07-251-3/+12
| | | | | | 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.
* cairo: Give missing spaces a better widthMatthias Clasen2019-07-071-0/+46
| | | | | We are not rendering hex boxes for missing spaces, so we don't need to give them the hex box width.
* Remove an unused labelMatthias Clasen2019-07-061-1/+0
|
* Add line height to font metricsMatthias Clasen2019-07-051-14/+24
| | | | Add a getter for the line height of a font.
* 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.
* Add assertions to guard against division by zero on sample text pathsPhilip Withnall2017-02-141-1/+4
| | | | | | | | | | | | | There are a few code paths where pango_utf8_strwidth() is called on language-specific sample text. The sample text should have been chosen to never have a zero width, but we should add some assertions to ensure that’s the case. This guides static analysers into the right analysis.
