Fields

buffer_id: FilterOpGraphPictureBufferId

Id of the picture in question in a namespace unique to this filter DAG, some are special values like FilterPrimitiveDescription::kPrimitiveIndexSourceGraphic.

subregion: LayoutRect

Set by wrap_prim_with_filters to the subregion of the input node, may also have been offset for feDropShadow or feOffset

offset: LayoutVector2D

During scene build this is the offset to apply to the input subregion for feOffset, which can be optimized away by pushing its offset and subregion crop to downstream nodes. This is always zero in render tasks where it has already been applied to subregion by that point. Not used in get_coverage_svgfe because source_padding/target_padding represent the offset there.

inflate: i16

Equal to the inflate value of the referenced buffer, or 0

source_padding: LayoutRect

Padding on each side to represent how this input is read relative to the node’s output subregion, this represents what the operation needs to read from ths input, which may be blurred or offset.

target_padding: LayoutRect

Padding on each side to represent how this input affects the node’s subregion, this can be used to calculate target subregion based on SourceGraphic subregion. This is usually equal to source_padding except offset in the opposite direction, inflates typically do the same thing to both types of padding.
