Struct webrender::composite::CompositorTransform
source · pub struct CompositorTransform {
local_to_surface: ScaleOffset,
surface_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.
