Fields

rect: Rect

local_rect: Rect

quad: [[f32; 2]; 4]

brush: Brush

shape: Option<RoundedCornerShape>

stroke: Option<Stroke>

Some means “stroke the outline of local_rect/shape” instead of filling it. The width is already in local_rect units (the layer scale has been applied), and local_rect/quad have already been inflated by half that width so the outer half of the stroke has geometry to land on.

arc: Option<ArcGeometry>

Some replaces the rect geometry entirely with a circular band. The center and radii are in local_rect units.

clip: Option<Rect>

blend_mode: BlendMode

motion_context_animated: bool
