Add custom palettes for COLRv1 and SVG fonts
See merge request cairo/cairo!417
|
| | | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
Only loop over custom colors if we got
a palette selected successfully.
|
| | | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
When the font options contain a custom palette,
overwrite the palette we got from freetype with
the custom entries.

| | | | |
| | | | |
| | | | |

Add a way to define a custom color palette as
part of cairo_font_options_t. To use the custom
palette when rendering color fonts, set the palette
index to CAIRO_COLOR_PALETTE_CUSTOM.

It an unnecessary complication for use to pass
the palette index, and have the COLRv1 renderer
pull the palette out of the FT_Face, after we
just selected it.

We were returning the number of palettes where
the number of palette entries was expected,
leading to array overruns. Oops

cairo_font_options_t has grown to have malloc'ed memory,

Fix shared use of recording surfaces

The problem is _cairo_recording_surface_replay_and_create_regions()
stores the cairo_recording_region_type_t in the same structure as the
recording commands. This does not work well when the recording surface
is used as source by multiple surfaces
Fix this by moving the cairo_recording_region_type_t into a separate
struct cairo_recording_regions_array_t. This struct is stored in a
list that allows multiple create regions results to be store in the
surface.
The new function _cairo_recording_surface_region_array_attach() is
used to create a new cairo_recording_regions_array_t, attach it to the
recording surface and return a unique region id.
The _cairo_recording_surface_replay_and_create_regions() and
_cairo_recording_surface_replay_region() functions use this region id
to identify the cairo_recording_regions_array_t.
To handle nested recording surfaces, when replaying a recording, the
region id is passed to the target as an extra parameter in the surface
pattern. The wrapper surface makes a temporary copy of the pattern to
ensure the snapshot pattern in the recording surface is not modified.
cairo_recording_regions_array_t has a reference count so the target
can hold on to the cairo_recording_regions_array_t after the paginated
surface has called _cairo_recording_surface_region_array_remove().

different surfaces
There is a bug in the recording surface where if one recording surface
is used as the same source on different paginated targets that support
fine grained fallbacks, the output may be incorrect because the
analysis results of a previous target are re-used on another target.

Add test for loading 16 bit PNG images
See merge request cairo/cairo!241

The base image has 16 bits per channel, with colors that do not
have an exact corresponding 8 bit representation. The reference
image uses 8bpc, like the rgb24/argb32 formatted images which
the test outputs.
|

This makes it possible to read cairo-script files which embed
RGB30/RGB96F/RGBA128F images.
|
| | | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
Before this change, images with RGB30, RGB96F, and RGBA128F formats
would have been given garbage xrender formats; now such images
use the fallback path and are converted to formats with an xrender
equivalent.

Defining Windows version macros in meson.build

WINVER and _WIN32_WINNT macros were defined in each source files and
headers that were including <windows.h>. However, because DirectWrite
requires new Windows API, some files included <windows.h> without the
version macros. This inconsistency sometimes caused troubles.
Define the version macros in meson.build.

`_cairo_status_set_error` was using `_cairo_atomic_int_cmpxchg` to set
a `cairo_status_t` variable by casting a `cairo_status_t*` to
`cairo_atomic_int_t*`. `cairo_atomic_int` has a generic implementation
which is using a mutex. In the implementation, `cairo_atomic_int_t`
was typedef-ed to `cairo_atomic_intptr_t`. In a typical 64bit system,
cairo_atomic_intptr_t is 64bit and cairo_status_t is 32bit,
_cairo_status_set_error didn't work as expected.
Define `cairo_atomic_int_t` as an alias of `int`.
Added an assertion in `_cairo_status_set_error` to ensure
that `*err` has the same size with `cairo_atomic_int_t`.

There was an assertion in
`_cairo_recording_surface_acquire_source_image` to ensure the surface

`record-paint` test on Windows.
Removed the assertion and return `CAIRO_INT_STATUS_UNSUPPORTED` if the
surface is unbounded.

GeometryRecorder class was calling _controlfp_s with MCW_PC to reset
the floating point precision to default. However, MCW_PC isn't
supported for ARM or x64 platforms. It reports an assertion failure
for them. And, Cairo isn't changing the MCW_PC setting. Removed the
calls. Also, removed `GetFixedX` and `GetFixedY` methods because they
called only `_cairo_fixed_from_double`.
