BUGS ChangeLog ROADMAP TODO
Log Message:
2005-08-06 Carl Worth <cworth at cworth.org>
* BUGS: Remove several bugs that have been fixed.
* ROADMAP: Slip group support off of the 1.0 roadmap. Update
status of clipping work which otaylor is working on.
* TODO: 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.
* src/cairo-gstate.c (_cairo_gstate_set_font_face): Don't crash if
font_face is NULL, (this is a documented mechanism for returning
to the default font_face).

-cairo_show_surface fails when given a non-default CTM, see the
-show_surface.cairo snippet in:

- Message-Id: <1108008335.5349.46.camel at localhost.localdomain>
- Subject: [cairo] How is cairo_show_surface supposed to work?
-
---
-
cairo_image_surface_create should return a blank image
(eg. transparent black) instead of an image with random data in it.
--
-cairo_surface_create_for_image is claiming ownership of the user's data.
-
---
-
-cairo_font_set_transform should be renamed cairo_font_set_matrix
-cairo_font_current_transform should be renamed cairo_font_get_matrix
-
---
-
-Alexis Georges reports a segfault on AMD64 with a simple program,
-(that works in a 32bit chroot).
-
---
-
-The caches need to have some locking (see: [cairo] Static caches and thread-safety)
-
---
-
Scaling of surface patterns is all broken, (try xsvg
gradPatt-pattern-BE-07.svg and zoom in and out).

Details on some of the above changes
------------------------------------
-* cairo_surface_mark_dirty
-
- One question is what the function should accept. A single
- device-space rectangle seems like a consistent approach. That would
- allow us to avoid needing backend-specific functions with
- backend-specific region datatypes, (cf. clipping support)
-
- In order to get the intended efficiency benefits, we'll need to make
- two changes:
-
- 1) In the fallback code, never fetch any data from the clean
- region.
-
- 2) Mark clean any region drawn with device-pixel aligned
- rectangles, (cairo_paint with no clip is the most iportant
- one here).
-
* cairo_text_glyphs:
It would function as a sort of bridge between the toy and the

current path. We may also need to provide the coordinates of the
faces of every dash as well.
-* split cairo_format_t into two things:
-
- - An enumeration that determines the "capabilities" of a surface -
- A vs. ARGB. vs. RGB
- - An enumeration that determines a specific in-memory representation
- of data. (A1/A8/ARGB32/etc.. Could be extensible to things like
- RGBA32_BYTES_NONPREMULTIPLIED. Some consistent naming convention would
- be be good.)
-
- One issue here is that some interfaces, like cairo_surface_create_similar()
- might be useful with either one. We might want to create an A1 surface
- compatible with the backend (are there examples other than A1? Should
- bilevel just be another "capability"?), or we might want to just create
- an alpha surface without caring about the depth.
-
- If we want to support this, we could do something like:
-
- typedef enum cairo_pixel_format_t {
- CAIRO_PIXEL_FORMAT_A8 = CAIRO_FORMAT_ALPHA,
- CAIRO_PIXEL_FORMAT_RGB24 = CAIRO_FORMAT_RGB,
- CAIRO_PIXEL_FORMAT_A1,
- };
-
- To allow passing either in.
-
- (I don't particularly like this idea for create_similar() because then you
- aren't really saying ALPHA-dont-care, you are saying ALPHA-8. I think it
- would be better to have a separate path for create_similar_with_pixel_format()
- if we need that. But it might be useful for cairo_image_surface_create() ...
- people are going to screw up and pass CAIRO_FORMAT_RGB into that, and if it
- "just worked" that would save people trouble....)
-
Changes that do not affect the public API
=========================================
-* Clean up the cache code a bit, (there is at least one redundant
- level of cacheing, and there are some minor style issues).
-
* Fix clipping to work for all operators. The equation we have come up
with is:
((src Op dest) In clip) Add (dest Out clip)
-* Make a more interesting PS backend, (other than the current
- "giant-image for every page" approach).
-
* Change stroke code to go through one giant polygon. This will fix
problems with stroking self-intersecting paths.
