29da47be60 [ps] Check for an empty font subset. 
Return early before trying to emit an empty subset into the document -
avoids a potential use of an uninitialised status variable.

fd1f3c27e0 [configure] Check for atomic xchg. 
Bug 18140 identifies a case where we have an atomic increment, but not an
atomic exchange. We need both to implement atomic reference counting, so
add a second check to detect whether __sync_val_compare_and_swap
generates a non-atomic instruction.

Fixes http://bugs.freedesktop.org/show_bug.cgi?id=18140.

71e4f7e3a1 Add API documentation for NULL filenames and write_funcs. 
Mention in the API docs that you can pass a NULL filename to
cairo_(pdf|ps|svg)_surface_create in order to construct a queryable
surface without generating any temporary files. Similarly when passing a
NULL write_func to cairo_pdf_surface_create_for_stream et al.

ae9d17c015 [directfb] Unbounded operators are unsupported. 
Currently the emulation of Porter-Duff operators does not correctly
handle the unbounded operators.

1f35f31c4e [directfb] Fallback for SATURATE 
We're unable to satisfactorily emulate SATURATE using the src/dst blend
modes, so fallback. (Might just be a bug in libdirectfb...)

c7951c4a36 [directfb] Perfom text fallback if emulating clip regions. 
Fallback if we have a clip that is not a simple region.

98933fd4b8 [directfb] When blitting check if we need the un-premultiplied color. 
When blitting whether we need to use the premultiplied color is dependent
upon the destination surface capabilities.

4af8aa5f4d [directfb] Apply clip to release_dest_image() 
We need to respect the current clip when copying the fallback image back to
the target surface.

0ba5085ba0 [directfb] Fix OBO in clip. 
DirectFB seems to use inclusive upper bounds.

2743e84171 [directfb] Force NEAREST. 
The current version of DirectFB does not support any filters, so set
NEAREST on the source patterns so that we can fully optimize the pattern
inside core.

f1669d31c0 [directfb] Track the empty clip rectangle. 
A region with no extents means everything should be clipped out, so we
need an extra flag to disambiguate when we have 0 clip rectangles.

ebe3048f9b [directfb] Cap the maximum surface size to use for the font cache. 
Fallback if we need to create a cache larger than the maximum usable
surface.
 2008-10-20 23:20:23 +01:00
Chris Wilson
6f35c2d13e [directfb] Only use the pure BLIT for integer translations. 
If we have non-integer translation on a source pattern then we need to use
STRECTHBLIT (the core takes care to optimize NEAREST patterns to integer
translations so that this will only be used when interpolation is
required).

55bb7087b0 [directfb] Tweak _categorize_operation(). 
Explicitly list the extend modes that are supported/unsupported and
immediately check for an unsupported operation.

edb65213ec [directfb] Support ROI cloning. 
Only clone the ROI in order to efficiently handle large sources.

4006e49ac1 [directfb] Rename backend structure. 
Use _cairo_directfb_surface_backend for consistency with other backends.

7e31ddbb08 [directfb] Whitespace. 
Trim lots of trailing whitespace and fix up according to CODING_STYLE.
 2008-10-20 23:20:23 +01:00

d49563280b [directfb] Simplify return from _directfb_get_operator(). 
Used only as a predicate, so simply return a boolean.
 2008-10-20 23:20:22 +01:00
Chris Wilson
b17d0ded8c [directfb] Use the solid pattern cache. 
The dfb backend recreated a solid color surface for every colour,
completely bypassing the solid pattern cache.

786bea48df [boilerplate/directfb] Create ARGB surfaces on demand. 
Create an RGB or ARGB surface depending upon the content type of the test
target, with the result that the directfb rgb24 target no longer
unconditionally fails.

4ba9ccc6ab [configure.ac.analysis] s/safe/_save/ 
Rename the temporary variable in line with the convention used by the rest
of the build system.

86356a9578 [test] Add degenerate-dash to XFAIL. 
PS (ghostscript) interprets the degenerate end-caps quite differently, and
perhaps slightly more rationally... Add this to XFAIL, until we have a
definitive specification on how we should behave.

eab37f76b0 [directfb] Return an error surface on create() failure. 
Do not return NULL but an NO_MEMORY error surface if we fail to allocate
the surface during creation.

aba457fe64 [directfb] Add missing error status 
We jumped to the ERROR path without setting an error status - assume
NO_MEMORY.

610451e4a7 [directfb] Correct fixed-to-double conversion. 
The trapezoid calculations had not been updated after the 16.16->24.8
switch. Use _cairo_fixed_to_double() rather than open-coding.
 2008-10-19 12:45:45 +01:00
Chris Wilson
8e0950ced8 [boilerplate/directfb] Gracefully handle failure to create surface. 
Simply return NULL indicating failure to create the target surface rather
than aborting the test (allowing other targets to be tested).
 2008-10-19 12:32:41 +01:00
Chris Wilson
801df1b87a [directfb] Fix error propagation from surface_create() 
Do not mask fatal errors, but correctly propagate the error status.

f2ff794426 [perf] A crude tool to visualise performance changes across a series. 
Generate a cairo-perf-diff graph for a series of commits in order to be
able to identify significant commits. Still very crude, but minimally
functional.

41c8eefc6d [output-stream] Protect against NULL write_func. 
Allow the user to specify a NULL write_func for the output stream so that
a dummy surface can be created, for example, for querying target font
options or font extents.

Currently we do not perform any sanity checks at the user entry point and
will generate a mysterious SEGV during cairo_surface_finish() - which may
not immediately be obvious that it is due to a NULL write_func.

Chris Wilson
84e4a825ff [output-stream] Accept a NULL filename 
Principally to support creating a dummy vector surface (i.e.
cairo_ps_surface_create (NULL, 1, 1)) that can be used to determine font
extents (or target font options) before opening an output file, but also
because we currently fail to do any sanity checking at the entry point.

52ea38f97b [meta] Acquire scaled_font mutex for glyph_path(). 
The caller of _cairo_scaled_font_glyph_path() is expected to be holding
the scaled_font->mutex.

299ea0580a [user-font] Review locks under error conditions. 
Simplify the error handling by only relinquishing the global
scaled_font_map mutex if we successfully insert the placeholder font. The
result is that on the error path, there are no changes to global state and
thus we can entirely skip the user-font initialisation and
re-registration.

c76a8481f3 [analysis] Check for error surfaces. 
If the target surface is an error surface, ensure that we return the
appropriate error surface. Likewise, avoid writing to error surfaces.

6b17c6da47 [type3] Acquire scaled_font mutex whilst looking up glyphs. 
When looking up the glyph in the shared scaled_font glyph cache, the
caller is required to have taken the scaled_font->mutex.

f56cf93181 [user-font] Check for error objects. 
Check that the user has not passed in an inert error object before any
attempts to write to it and return the default values.

1f9f9d936b [pdf] Acquire scaled_font mutex for show_text_glyphs(). 
We need to be holding the scaled font mutex over a call to draw text
glyphs from within an smask group.

12fb8c9b7c [type1] Acquire scaled_font mutex. 
In order to perform glyph lookups we need to be holding the mutex for the
scaled_font.
