- Changelog
14.2.0
- GPU library:
* New color-glyph paint renderer, based on design by Lê Duy Quang.
`hb_gpu_paint_t` walks a font's paint tree (COLRv0 or COLRv1) and
encodes
its layers (solid fills, linear / radial / sweep gradients,
transforms,
composite groups) into a compact blob.
A new fragment-shader function `hb_gpu_paint()` renders the blob in
premultiplied RGBA; monochrome glyphs are handled transparently via
a
synthesized foreground-colored layer.
Shader sources provided in GLSL, WGSL, MSL, and HLSL.
* Paint encoder limitations: the encoder sets `unsupported` and
returns
`NULL` when `num_ops` would exceed 32767, `push_group` nests deeper
than 4,
or the paint tree calls back through the image callback
(PaintImage).
Nested glyph clips are intersected up to 3 levels; a few composite
modes
use approximate fallbacks; `push_clip_rectangle` is silently
ignored.
* Encode entry point now returns extents and auto-clears the encoder;
the
standalone `get_extents()` is gone.
* Gradient color stop interpolation now happens in premultiplied
space per
the OpenType COLR specification.
* The foreground color sentinel (`is_foreground`) now correctly
preserves the
paint-tree alpha from the encoded color data instead of discarding
it.
* The hb-gpu utility gains `--draw` / `--paint` flags with per-font
auto-detect, and `--output-file` / `-o` for headless single-frame
rendering
to a PPM image.
- Vector library:
* New PDF output backend. Vector paint glyphs now render to PDF page
content,
producing scalable COLRv0 / COLRv1 color-glyph artwork (solid
fills, linear
/ radial / sweep gradients, blend modes, PNG images with
transparency) that
can be embedded directly in PDF documents. Useful for PDF producers
such as
LibreOffice that want crisp, resolution-independent color emoji.
* New SVG id prefix API on paint allows prefixing document
references, which
allows for embedding multiple SVGs in the same page without name
clashes
(`hb_vector_paint_set_svg_prefix`).
* Removed glyph path dedup from vector draw and paint. Each glyph is
emitted
inline; no `<defs>` / `<use>` caching.
* `_glyph()` functions are now thin convenience wrappers documented as
equivalent expansions of the underlying font draw/paint API.
* Drop glyph-source rendering of SVG-in-OT fonts.
- Raster library:
* Drop glyph-source rendering of SVG-in-OT fonts.
- Across Draw / Paint subsystems:
* `_reset()` methods gain matching`_clear()` companions that drop
accumulated
data while preserving user configuration. Getter companions added
for
setters across raster, vector, and gpu types.
- Various fuzzer fixes for raster, vector, and GPU libraries.
- Paint API:
* New arbitrary-path clip: `hb_paint_push_clip_path_start` / `_end`
let
callers clip to a caller-supplied outline, not just a font glyph.
`push_clip_path_start()` returns the draw-funcs (and matching draw
data)
for the backend’s path accumulator; the caller drives `hb_draw_*()`
into
it, then calls `push_clip_path_end()`, followed by painted ops, then
`hb_paint_pop_clip()` to release the clip. Implemented for all paint
backends: vector (SVG defs + clipPath + url ref), vector PDF (q /
path / W
n), raster (path rendered to an alpha mask, intersected with the
current
clip), and GPU (the path is encoded into a Slug sub-blob so the
fragment
shader clips against it the same way it clips against glyph
outlines).
- Shaping:
* Indic: categorize U+1CF5 and U+1CF6 as CS.
- Changed API
* GPU library:
- `hb_gpu_draw_glyph()` now returns `void` (was `hb_bool_t`). Use
`hb_gpu_draw_glyph_or_fail()` if you need the success status.
- `hb_gpu_paint_glyph()` now returns `void` (was `hb_bool_t`) and
internally synthesizes a foreground-colored layer for non-color
glyphs
via `hb_font_paint_glyph()`, so every glyph with an outline
produces
output. Use `hb_gpu_paint_glyph_or_fail()` (which delegates to
`hb_font_paint_glyph_or_fail()`) if you need to distinguish color
vs
synthesized paint. Encoder-level limits (unsupported ops,
group-stack
overflow) no longer fail paint_glyph; they surface from
`hb_gpu_paint_encode()` returning `NULL`.
- `hb_gpu_draw_encode()` now takes an `extents` out-parameter and
auto-clears the encoder on return.
- `hb_gpu_draw_darken()` renamed to `hb_gpu_stem_darken()`.
* Vector library:
- `hb_vector_svg_set_precision()` and its paint counterpart renamed
to
`hb_vector_draw_set_precision()` /
`hb_vector_paint_set_precision()`
(SVG-specific naming is inaccurate with the PDF backend added).
- `hb_vector_draw_glyph()` / `hb_vector_paint_glyph()` now return
`void`
(were `hb_bool_t`). Paint additionally gains a draw fallback for
non-color glyphs. Use the matching `_or_fail()` variants for the
`hb_bool_t` return.
* Raster library:
- `hb_raster_draw_glyph()` / `hb_raster_paint_glyph()` now return
`void`
(were `hb_bool_t`). Paint additionally gains a draw fallback for
non-color glyphs. Use the matching `_or_fail()` variants for the
`hb_bool_t` return.
* General:
- Many read-only getters gained const on their object argument.
- Six public draw / paint funcs getters across raster, vector, and
gpu now
take a const-pointer to the relevant context instance instead of
being
singletons:
hb_raster_draw_get_funcs (const hb_raster_draw_t *)`
hb_raster_paint_get_funcs (const hb_raster_paint_t *)
hb_vector_draw_get_funcs (const hb_vector_draw_t *)
hb_vector_paint_get_funcs (const hb_vector_paint_t *)
hb_gpu_draw_get_funcs (const hb_gpu_draw_t *)
hb_gpu_paint_get_funcs (const hb_gpu_paint_t *)
This is what lets vector_paint dispatch to SVG- vs PDF- flavored
callbacks transparently when called from outside code; the others
currently use the instance for symmetry only.
