* tabs: Add a decimal pointMatthias Clasen2021-11-291-0/+1
| | | | | | | This is useful for PANGO_TAB_DECIMAL. Implement this in PangoLayout, in the serializer, and update tests.
* Add horizontal displacementMatthias Clasen2021-08-311-2/+3
| | | | | | | | | | | Apply horizontal displacements for superscripts and subscripts that are provided in font metrics. This noticably improves the placement of superscripts in italics. Currently, we only apply these displacements in post-processing, and ignore the width changes during line-breaking. This could be improved by moving the baseline handling into the line-breaking proper.
* Add pango_justify_last_lineMatthias Clasen2021-08-101-0/+1
| | | | | | | Add a way to justify the last line in a justified paragraph. Fixes: #74
* Use shape flags for ellipsisMatthias Clasen2019-11-031-0/+1
| | | | | | | When shaping the ellipsis, use the same shape flags we use for the rest of the layout, otherwise we end up with subtle size differences between an ellipsized text and a plain …
* layout: Add line-spacingMatthias Clasen2019-07-051-0/+1
| | | | | | | | | | | | | | If line-spacing is set to a non-zero value, we place lines so that baseline2 = baseline1 + line-spacing * height2 where height2 is the line height of the second line. In this case, we ignore spacing. If line-spacing is set to zero, spacing is applied as before.
* PangoLayoutIter: Allocate an array of Extents instead of a linked listTimm Bäder2017-10-271-2/+13
| | | | | | | | Since PangoLayout caches the amount of lines it contains in ->line_count, we can use this to pre-allocate an Extents array of the appropriate size. https://bugzilla.gnome.org/show_bug.cgi?id=788643
* layout: Move PangoLayouIter struct to private headerTimm Bäder2017-10-271-0/+53
| | | | | | | And add _pango_layout_get_iter as well as _pango_layout_iter_destroy that can be used for internal, stack allocated PangoLayoutIters. https://bugzilla.gnome.org/show_bug.cgi?id=788643
* Track changes in layout and dependencies via serialsAlexander Larsson2012-12-061-0/+3
| | | | | | | | | We track changes in the PangoContext and automatically call pango_layout_context_changed() when needed, plus we track changes in the layout and let apps know via pango_layout_get_serial when the layout changed and needs to be redrawn. https://bugzilla.gnome.org/show_bug.cgi?id=340066
* Bug 594934 - pango_layout_copyBehdad Esfahbod2009-09-111-12/+15
| | | | Use memcpy() to copy value fields so we don't miss any.

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