Bug 135683 – Cache glyphstring extents
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. Line extents are cached only if the user doesn't
have a pointer to the line or any of its runs. Functions that give
away such pointers mark the line as "leak"ed.
* pango/pango-layout.c (pango_layout_index_to_line_and_extents),
(pango_layout_xy_to_index), (pango_layout_index_to_pos):
Use _pango_layout_iter_get_line() which is like
pango_layout_iter_get_line() but doesn't leak the line.
* pango/pango-layout-private.h: Add pango_layout_iter_get_line()
duplicate _pango_layout_iter_get_line_readonly() that doesn't leak
the line.
* pango/pango-renderer.c (pango_renderer_draw_layout): Use
_pango_layout_iter_get_line_readonly().
