Functions

get_coverage_source_svgfe

Here we transform target rect to source rect for SVGFEGraph by walking the whole graph and propagating subregions based on the provided invalidation rect, and we want it to be a tight fit so we don’t waste time applying multiple filters to pixels that do not contribute to the invalidated rect.

get_coverage_target_svgfe

Here we transform source rect to target rect for SVGFEGraph by walking the whole graph and propagating subregions based on the provided invalidation rect, and we want it to be a tight fit so we don’t waste time applying multiple filters to pixels that do not contribute to the invalidated rect.
