Struct webrender::composite::CompositorTransform

source ·
pub struct CompositorTransform {
    local_to_raster: ScaleOffset,
    raster_to_device: ScaleOffset,
    local_to_device: ScaleOffset,
}
Expand description

A transform for either a picture cache or external compositor surface, stored in the CompositeState structure. This allows conversions from local rects to raster or device rects, without access to the spatial tree (e.g. during the render step where dirty rects are calculated). Since we know that we only handle scale and offset transforms for these types, we can store a single ScaleOffset rather than 4x4 matrix here for efficiency.
