Enum webrender::quad::QuadRenderStrategy

pub enum QuadRenderStrategy {
    Direct,
    Indirect,
    NinePatch {
        radius: LayoutVector2D,
        clip_rect: LayoutRect,
    },

    },
}

Describes how clipping affects the rendering of a quad primitive.

As a general rule, parts of the quad that require masking are prerendered in an intermediate target and the mask is applied using multiplicative blending to the intermediate result before compositing it into the destination target.

Each segment can opt in or out of masking independently.

Variants

Direct

The quad is not affected by any mask and is drawn directly in the destination target.

Indirect

The quad is drawn entirely in an intermediate target and a mask is applied before compositing in the destination target.

NinePatch

A rounded rectangle clip is applied to the quad primitive via a nine-patch. The segments of the nine-patch that require a mask are rendered and masked in an intermediate target, while other segments are drawn directly in the destination target.

Fields

radius: LayoutVector2D

clip_rect: LayoutRect

Tiled

Split the primitive into coarse tiles so that each tile independently has the opportunity to be drawn directly in the destination target or via an intermediate target if it is affected by a mask.

Fields

x_tiles: u16

y_tiles: u16
