Public Member Functions
bool	empty () const
	Returns true if the graph has no nodes.

Public Attributes
std::vector< FilterNode >	nodes
	Nodes in document (execution) order.
ColorInterpolationFilters	colorInterpolationFilters = ColorInterpolationFilters::Default
	Color space for filter operations (linearRGB or sRGB).
PrimitiveUnits	primitiveUnits = PrimitiveUnits::Default
	Coordinate system for primitive subregion and primitive-specific length attributes.
std::optional< Box2d >	elementBoundingBox
	Bounding box of the referencing element, used when primitiveUnits=objectBoundingBox. Set by the renderer driver before passing to the renderer.
std::optional< Box2d >	filterRegion
	The filter region in user-space coordinates.
Vector2d	userToPixelScale = Vector2d(1.0, 1.0)
	Scale factor from SVG user-space coordinates to pixel-space coordinates. Needed by lighting filters to transform light positions from user space to the pixel-space pixmap. Set by the renderer driver from the viewBox and canvas dimensions.

Detailed Description

The complete filter graph for a <filter> element.

Contains an ordered list of filter nodes derived from the filter element's children. The output of the last node is the filter result that gets composited onto the canvas.
