Slip group support off of the 1.0 roadmap. Update status of clipping work which otaylor is working on. Update for progress on cairo_surface_mark_dirty (committed), non-antialiased rendering (patch), cairo_arc_to (patch), consistent error handling (committed), cairo_content_t (committed). Remove details for some completed items. Don't crash if font_face is NULL, (this is a documented mechanism for returning to the default font_face).

|
|
Details on some of the above changes
|
|
------------------------------------
|
|
* cairo_text_glyphs:
|
|
|
|
It would function as a sort of bridge between the toy and the
|
|
real text APIs:
|
|
|
|
> void
|
|
> cairo_text_glyphs (cairo_t *cr, const unsigned char *utf8,
|
|
> cairo_glyph_t *glyphs, int *num_glyphs);
|
|
>
|
|
> with num_glyphs as an input-output parameter. The behavior of this
|
|
> function would be such that calling:
|
|
>
|
|
> cairo_text_glyphs (cr, string, glyphs, &num_glyphs);
|
|
> cairo_show_glyphs (cr, glyphs, num_glyphs);
|
|
>
|
|
> would be equivalent too:
|
|
>
|
|
> cairo_show_text (cr, string);
|
|
>
|
|
> as long as the original size of glyphs/num_glyphs was large
|
|
> enough.
|
|
|
|
* support for custom caps:
|
|
|
|
It would be nice if the user had a mechanism to reliably draw custom
|
|
caps. One approach here would be to provide the coordinates of the
|
|
butt cap faces so that the user can append seamless caps to the
|
|
current path. We may also need to provide the coordinates of the
|
|
faces of every dash as well.
|
|
|
|
Changes that do not affect the public API
|
|
=========================================
|
|
* Fix clipping to work for all operators. The equation we have come up
|
|
with is:
|
|
|
|
((src Op dest) In clip) Add (dest Out clip)
|
|
|
|
* Change stroke code to go through one giant polygon. This will fix
|
|
problems with stroking self-intersecting paths.
|
|
|
|
* Fix the intersection problem, (see reference to Hobby's paper
|
|
mentioned in cairo_traps.c).
|
|
|
|
* Implement dashing for cairo_curve_to.
|
|
|
|
* Stroking closed, degenerate paths should still draw caps. Round
|
|
caps are easy; square should probably draw an axis-aligned square.
|
|
|
|
* Should add geometry pruning as appropriate.
|
|
|
|
* Verification, profiling, optimization.
