Struct VelloCPUDrawTarget

pub(crate) struct VelloCPUDrawTarget {
    ctx: RenderContext,
    pixmap: Pixmap,
    clips: Vec<Path>,
    state: State,
}

Fields

ctx: RenderContext

Because this is stateful context caller cannot assume anything about transform, paint, stroke, so it should provide it’s own used by each command but it can assume paint_transform to be identity and fill rule to be peniko::Fill::NonZero

This is because paint_transform is rarely set, so it’s cheaper to always reset it after use.

pixmap: Pixmap

clips: Vec<Path>

state: State
