Behdad Esfahbod c5f903872f [paint] Add bitmap width/height to paint_image callback
Such that we can add raw data as well.
2022-12-23 13:37:59 -07:00
Behdad Esfahbod 237955dffc [paint] Add slant to image() callback
And slant images in hb-view.

Matthias Clasen c221933977 [paint] Preserve foreground information 2022-12-23 13:37:59 -07:00
Matthias Clasen 6387004cad [paint] Simplify api
Drop the hb_paint_context_t struct from the API, and
only pass the font where we need it.
2022-12-23 13:37:59 -07:00
Matthias Clasen 71bd5a0dfc [paint] Resolve colors
We don't need to pass the index/alpha pairs to
client callbacks, and can just resolve the colors
internally.

Update test results.

Matthias Clasen 9be01b6bff [paint] Pass hb_paint_context_t along
Replace the font argument with a hb_paint_context_t
that carries the font, the palette index and the
foreground color.

The hb_font_paint_glyph() api now takes the palette
index and the foreground color as extra arguments.

Update all callers and regenerate test results.

Behdad Esfahbod 8495395397 [paint] Fix slant 2022-12-23 13:37:59 -07:00
Matthias Clasen 97224f3b63 [paint] Pass font to all callbacks
This will lead to easier implementations.

At the same time, we change the push_clip_glyph
callback to use the font as-is, no unscaling needed.

Update all callers and expected test results.

Matthias Clasen 0a2f3673b9 [paint] Use tags for image formats
This fits better with the rest of the

Matthias Clasen 686e627bdf [paint] Set up root transform in one place
Instead of spreading this in all the tables,
make hb_paint_funcs_t provide a push/pop_root_transform
that does all the setup.

Matthias Clasen 485ba9beb3 [paint] Spell out rectangle in the API
No need to abbreviate this.
2022-12-23 13:37:59 -07:00
Matthias Clasen 37f3f0fcc2 [paint] Change the image callback
Instead of passing the glyph ID, give
it the image blob, a mimetype, and
glyph extents (if available).

Update all callers.
2022-12-23 13:37:59 -07:00
Matthias Clasen 82e23f322a paint: Add a paint-image callback
This will be used for image blobs like pngs and svgs.

FIXME: nail down and document sizing.
2022-12-23 13:37:59 -07:00
Matthias Clasen 0d890061d1 Rename 'solid' to 'color'
'solid' does not really describe well what
the function does, and there is no strong
reason to stick 1:1 to the terminology used
in the spec.
