Behdad Esfahbod 56a48f8b0a [paint] Don't use extents in hb-view
Let the clipbox do its magic. Currently works for ft backend only.

Matthias Clasen ecd7420456 Debug spew
To get a dump of the hb-paint callbacks,
set HB_PAINT_DEBUG=1 when running hb-view.

For now, leave this code in place, since it
comes in handy for various debugging.

Matthias Clasen 13e0cb64f4 hb-view: Interpolate gradients premultiplied
This is what the specs demand.

Behdad Esfahbod 381d410b1e [paint] Add HB_PAINT_IMAGE_FORMAT_BGRA and use it in hb-ft
Now hb-ft can render color emoji as well.

Just left COLRv2.

Behdad Esfahbod c5f903872f [paint] Add bitmap width/height to paint_image callback
Such that we can add raw data as well.

Behdad Esfahbod 237955dffc [paint] Add slant to image() callback
And slant images in hb-view.

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 d094e76cbc hb-view: Pass fg color to hb_font_paint_glyph 2022-12-23 13:37:59 -07:00
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.

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 5451b78f4a Don't use alloca
It complicates things on Windows, for no
big win. Just preallocate a reasonable amount.

Matthias Clasen c65f580b93 Drop hb-test
This was a test binary to assist in developing
the hb-paint code. Not needed anymore, now that
hb-view has the same code in the cairo userfont
backend.

Extents are wrong but at least renders something now.

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.
