-cairo 1.0 release requirements
-==============================
-Implementation work
--------------------
-✓I1. Fix clipping to be sane
- Status: Done (in cairo 0.9.0).
+cairo 1.0.2 required fixes (Schedule unknown)
+=============================================
+[Need to look through bugzilla, particularly at new bugs filed since
+the 1.0.0 release]
-✓I2. Real PostScript/PDF fallbacks (cairo_meta_surface_t)
- Status: Done (to some extent) (in cairo 0.5.2)
+cairo 1.2.0 desired features (Scheduled for 2005-11-01)
+=======================================================
+ A. PS backend
+ ----------
+ 1. Mark PS backend as supported:
- We do have PDF output now, and "real" PostScript
- output on a per-page basis when the capabilities of
- the PostScript imaging model aren't exceeded. There
- are a few parts of these backend that aren't complete,
- but that will have to wait for post-1.0 I'm afraid.
+ a. Incorporate into test suite
-✓I3. Add support for sub-pixel (ARGB) rendering of text.
- Status: Done (in cairo 0.6.0).
+ b. Correct output for the entire test suite
-✓I4. Fix the cache lock deadlocking problems.
- Status: Done (in cairo 0.9.2)
+ 2. Image fallbacks at finer-than-whole-page granularity
-✓I6. Fix all expected failures (XFAIL) in the test suite. Either
- there's a bug that needs to be fixed, or there are illegitimate
- tests that should be removed.
- Status: Done. 5 XFAIL test remain, but 4 of those have results
- that are acceptable. The only with with completely broken
- output (a8-mask) only happens with A8 image surface masks with
- weird padding, (so it is easy to avoid).
+ B. PDF backend
+ -----------
+ 1. Mark PDF backend as supported
-API additions (more detail in TODO file)
-----------------------------------------
-✓A7. cairo_surface_mark_dirty and cairo_surface_flush
- Status: Done (in cairo 0.9.0).
+ a. Incorporate into test suite
-✓A12. cairo_xlib_surface_set_drawable
- Status: Done (in cairo 0.6.0).
+ b. Correct output for the entire test suite (use image
+ fallbacks as necessary, meta-surface?):
-Performance work
-----------------
-✓ Lots of performance work was done, such as the MMX-ification of
- pixman, the addition of cairo-benchmarks, and several 2x improvements
- for tests within cairo-benchamarks. Many thanks to Billy Biggs!
+ a. Gradients with more than two stops
-Things that have been dropped from the 1.0 roadmap
-==================================================
- A3. Add cairo_begin/end/get_group
- Difficulty: easy to hard (depending on how sophisticated an
- implementation is acceptable, and whether the
- cairo_meta_surface_t mentioned in [I2] is done)
+ b. All of the cairo_operator_t modes
+
+ c. Gradients with transparency
+
+ d. Repeating surface patterns
+
+ e. cairo_mask
+
+ C. Win32 backend
+ -------------
+ 1. Incorporate into test suite
+
+ 2. Correct output for the entire suite
+
+ D. Bug fixes
+ ---------
+ 1. Fix dashed splines.
+
+ 2. Fix some expected failures (XFAIL) in the test suite
+
+ a. a8-mask
+
+ b. clip-all
+
+ c. filter-nearest-offset
+
+ d. pixman-rotate
+
+ E. API Additions
+ -------------
+ 1. cairo_begin/end/get_group
Status: cworth has a posted a preliminary patch, and keithp,
krh, and otaylor answered all the tough questions it
raised. There's not much work left to finish this one.
- I5. Finish the workaround for Render's overlapping source/dest bug
- (Copy the source as needed)
+ F. Performance improvements
+ ------------------------
+ 1. Cull and trim trapezoids outside clip region bounds
- The most important part of this was to workaround when doing a
- straight copy, (eg. for scrolling), and that much is done. The
- remaining case is things like overlapping OVER of a surface
- with itself, which doesn't seem useful enough to be a priority
- at this point.
+ 2. Generate more large pixel-aligned, rectangular trapezoids
- I7. Fine-grained PostScript fallbacks (cairo_meta_surface_t)
- Difficulty: Moderate to hard
- Status: cairo_meta_surface provides most of the
- mechanics. From here on out its mostly a matter of
- refining the fallbacks to work on a finer-grained
- basis than the current all-or-nothing-per-page
- approach.
+ ✓3. Speed up glyph measurement (cache rewrite)
- I8. Finish implementing the PDF/PostScript backends:
- Difficulty: Moderate to hard
- Status: Most everything is there, but there are few things in
- cairo that these backends don't yet implement:
+ G. SVG backend
+ -----------
+ 1. Add experimental SVG backend
- * Gradients with more than two stops
+cairo 1.4.0 desired features (Schedule unknown)
+===============================================
+ A. Quartz backend (maintainer needed!)
+ -----------------------------------
+ 1. Mark Quartz backend as supported:
- * All of the cairo_operator_t modes
+ a. Incorporate into test suite
- * Gradient with transparency
+ b. Correct output for the entire suite
- * Repeating surface patterns
+ B. SVG backend
+ -----------
+ 1. Mark SVG backend as supported
- * cairo_mask
+ a. Incorporate into test suite
- Some of these could be handled by fallbacks, either as
- a stop-gap measuer, or permanently. But that will also
- depend on finishing up [I7].
+ b. Correct output for the entire suite
- P2. Generate better trapezoids to go easier on the rasterizer
- Difficulty: moderate to hard
- Status: cworth drafted a plan to the list. vektor is looking
- at this, (or other similarly useful performance
- optimizations)
+ B. Performance improvements
+ ------------------------
+ 1. New tessellator (more robust and faster)
- P3. Glyph measurement needs to be sped up.
- Status: keithp and cworth planned this all out. keithp is
- working on this.
+ C. Bug fixes
+ ---------
+ 1. Fix all expected failures (XFAIL) in the test suite
+
+ a. self-intersecting
+ AKA. https://bugs.freedesktop.org/show_bug.cgi?id=3752
+ Fix depends on [A1].
