Struct webrender::picture::DirtyRegion

source ·

pub struct DirtyRegion {
    pub combined: WorldRect,
    spatial_node_index: SpatialNodeIndex,
}

Expand description

Represents the dirty region of a tile cache picture.

Fields§

§combined: WorldRect

The overall dirty rect, a combination of dirty_rects

§spatial_node_index: SpatialNodeIndex

Spatial node of the picture cache this region represents

Implementations§

source §

impl DirtyRegion

source

pub fn new(spatial_node_index: SpatialNodeIndex) -> Self

Construct a new dirty region tracker.

source

pub fn reset(&mut self, spatial_node_index: SpatialNodeIndex)

Reset the dirty regions back to empty

source

pub fn add_dirty_region( &mut self, rect_in_pic_space: PictureRect, spatial_tree: &SpatialTree, )

Add a dirty region to the tracker. Returns the visibility mask that corresponds to this region in the tracker.
