In particular, many possible error values on a surface provided
to cairo_pattern_create_for_surface were previously being swallowed
and a nil pattern was returned that erroneously reported
CAIRO_STATUS_NO_MEMORY.
This adds a new nil cairo_image_surface to hold CAIRO_STATUS_INVALID_FORMAT.
Previously the detected error was being lost and a nil surface was
returned that erroneously reported CAIRO_STATUS_NO_MEMORY.
The following documented symbols were missing this tag:
cairo_clip_extents
cairo_copy_clip_rectangles
CAIRO_STATUS_INVALID_INDEX
cairo_rectangle_t
cairo_rectangle_list_t
One of these functions was already documented to be doing this, and
the other one should have been. Now the documentation and behavior
for both are consistent, (and the path-data test case verifies this).
Adds API functions for inspecting the current dash state, as well as
the contents of pattern objects:
cairo_get_dash
cairo_get_dash_count
cairo_pattern_get_rgba
cairo_pattern_get_surface
cairo_pattern_get_color_stop_rgba
cairo_pattern_get_color_stop_count
cairo_pattern_get_linear_points
cairo_pattern_get_radial_circles
Inital commit of Native Quartz surface. The main missing functionality
is mask() support (which is just a noop right now, except for the simple
solid-alpha case).
Add support for the win32 surface using DDBs for similar surfaces and the
like when the orignal surface is created from a DC, or when a DDB is
explicitly created. A DIB is still created if alpha is required.
Also fixes a case where blitting win32 RGB24 -> ARGB32 surfaces was causing
alpha to leak into the ARGB32 surface instead of being set to fully opaque.
cairo_status_t is a signed type, so we need to check for invalid codes
that are < 0 as well.
Also removes the MSVC goop in path-data.c that was attempting to work
around the assert earlier.
There was a bad mix of LIBCMT (the static runtime lib) and MSVCRT (the dynamic
one) before, because LIBCMT is the default. This specifies /MD everywhere.
This patch adds a bunch of makefiles for building cairo with Visual C++.
gnu make is still required, and make must be run from a command prompt
that has the Visual C++ paths set up, as well as has the cygwin environment
in the path. Run 'make -f Makefile.win32'.
This adds a win32 initialization function that is called from all
surface creation and font creation functions to ensure that the win32
mutexes are initialized.
These functions were previously returning a status value that
was almost never being checked. Instead we now make these
functions void and enforce a usage pattern that the destination
array must be pre-grown to accomodate the results. This is
verified with a couple of assert statements.
The pre-allocation was already happening with all but one call.
That call is now also fixed up.
This object doesn't act like a status-holding object, (there are no
"if (status) return;" inertness-enforcing statements for example),
so it shouldn't pretend like it is.
This is a little simpler than the old idiom of calling
_cairo_output_stream_get_status just before calling
_cairo_output_stream_destroy.
I had hoped this technique would apply in more cases, but
many cases want to separate the two actions anyway to do
conditional assignment of the status value, (in order to
not overwrite an earlier error value).
