Struct AtlasCommandRecorder 

pub struct AtlasCommandRecorder {
    pub page_index: u32,
    pub commands: Vec<AtlasCommand>,
    pub(crate) width: u16,
    pub(crate) height: u16,
}

Records atlas draw commands for a single atlas page.

The recorder exposes the same method API as the actual renderers (RenderContext, Scene). It also implements DrawSink so that the COLR glyph painter can write into it directly.

Fields

page_index: u32

Which atlas page these commands target.

commands: Vec<AtlasCommand>

The recorded commands.

width: u16

Width of the glyph renderer / atlas page (pixels).

height: u16

Height of the glyph renderer / atlas page (pixels).

Implementations

impl AtlasCommandRecorder

pub fn new(page_index: u32, width: u16, height: u16) -> Self

Create a new recorder for the given atlas page.

width and height must match the glyph renderer dimensions (i.e. the atlas page size) so that COLR fill_solid / fill_gradient produce correctly-sized fill rects.
