Public Member Functions
bool	hasExplicitRegion () const
	Whether any authored primitive-region coordinate is present.
bool	hasAnimatedRegion () const
	Whether a contextual region stack is present, including a stack with no contributing value.

Public Attributes
FilterPrimitive	primitive
	The filter primitive operation.
std::vector< FilterInput >	inputs
	Input(s) to this primitive. A slot this list leaves unpopulated resolves exactly like an unspecified in/in2 attribute: to the previous primitive's result, and to SourceGraphic only when the node is the first primitive in the graph. A Composite, Blend, or DisplacementMap node built with a single input therefore reads the previous result as its second input, never the source graphic.
std::optional< RcString >	result
	Named output (for result attribute).
std::optional< Lengthd >	x
	Primitive subregion X.
std::optional< Lengthd >	y
	Primitive subregion Y.
std::optional< Lengthd >	width
	Primitive subregion width.
std::optional< Lengthd >	height
	Primitive subregion height.
std::array< std::shared_ptr< const ContextualLengthRecipe >, 4 >	animatedRegion {}
	Immutable deferred x/y/width/height stacks, evaluated in the executing filter's context.
std::optional< ColorInterpolationFilters >	colorInterpolationFilters
	Per-primitive color-interpolation-filters. When set, overrides the graph-level default.

Detailed Description

A single node in the filter graph, representing one filter primitive.

Nodes are executed in document order. Each node reads from its inputs (which may be standard inputs like SourceGraphic, or outputs of prior nodes), applies its primitive operation, and writes to an output buffer.
