Struct webrender::picture::BackdropInfo

source ·

pub struct BackdropInfo {
    pub opaque_rect: PictureRect,
    pub spanning_opaque_color: Option<ColorF>,
    pub kind: Option<BackdropKind>,
    pub backdrop_rect: PictureRect,
}

Expand description

Stores information about the calculated opaque backdrop of this slice.

Fields§

§opaque_rect: PictureRect

The picture space rectangle that is known to be opaque. This is used to determine where subpixel AA can be used, and where alpha blending can be disabled.

§spanning_opaque_color: Option<ColorF>

If the backdrop covers the entire slice with an opaque color, this will be set and can be used as a clear color for the slice’s tiles.

§kind: Option<BackdropKind>

Kind of the backdrop

§backdrop_rect: PictureRect

The picture space rectangle of the backdrop, if kind is set.
