Module renderer 

Shared glyph rendering logic for rendering backends.

Enums

CacheResult 🔒

Outcome of a cache-first render attempt.

Functions

calculate_raster_metrics 🔒

Calculate raster metrics (pixel bounds, bearings) from a glyph’s bounding box.

fill_glyph 🔒

Fill a prepared glyph, using the glyph atlas when possible and falling back to direct rendering otherwise.

fill_uncached_outline_glyph 🔒

insert_and_render_bitmap 🔒

insert_and_render_colr 🔒

insert_and_render_outline 🔒

Insert an outline glyph into the atlas and render it from there.

quality_for_scale

Choose image sampling quality based on downscale factor.

quality_for_skew 🔒

Choose image sampling quality based on skew presence.

render_bitmap_glyph_from_atlas 🔒

Render a bitmap glyph from the atlas cache.

render_cached_glyph 🔒

Render a cached glyph from the atlas.

render_colr_glyph_from_atlas 🔒

Render a COLR glyph from the atlas cache.

render_colr_to_atlas 🔒

Record COLR glyph draw commands into the atlas command recorder.

render_from_atlas 🔒

Render from the atlas, constructing the appropriate image from the slot.

render_outline_glyph_from_atlas 🔒

Render an outline glyph from the atlas using bearing-based positioning.

render_outline_to_atlas 🔒

Record outline glyph draw commands into the atlas command recorder.

render_uncached_bitmap_glyph 🔒

render_uncached_colr_glyph 🔒

replay_atlas_commands

Replay recorded atlas commands into a DrawSink.

stroke_glyph 🔒

Stroke a prepared glyph, using the glyph atlas when possible and falling back to direct rendering otherwise.

stroke_uncached_outline_glyph 🔒

supports_atlas_caching 🔒

Returns true if the transform is safe for atlas-cached glyph rendering.
