A shape ready for a renderer to draw, with the layer transform, paint and clip resolved.

Fields

rect: Rect

Axis-aligned bounds of quad.

local_rect: Rect

The shape’s rectangle after the layer’s scale and translation, before any rotation.

quad: [[f32; 2]; 4]

The shape’s rectangle after the full layer transform, as four corners.

brush: ResolvedBrush

Layer-resolved at emit time. Solid — effectively every shape of a heavy animated frame — is an inline color; only gradients carry a cloned Brush.

shape: Option<RoundedCornerShape>

Rounded corners of the shape, or None for sharp corners.

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.

line: Option<LineGeometry>

Some replaces the rect geometry entirely with a stroked segment, its ends and width in local_rect units.

trapezoid: Option<Trapezoid>

Some replaces the rect geometry entirely with a slice of a path fill, in local_rect units; local_rect is the rect its brush resolves against.

clip: Option<Rect>

Clip rectangle that cuts the shape, or None when nothing clips it.

blend_mode: BlendMode

How the shape blends onto what lies beneath it.

motion_context_animated: bool

Whether the shape sits in an animated motion context, where a renderer must not snap it to the pixel grid.
