The clip list is a list of rectangles in device coordinates that define the areas of the drawable in which rendering may occur. If the list is Null, then the entire drawable is eligible. If the list is not Null, then rendering occurs only in those pixels that are within the rectangles specified in the list. Overlapping rectangles in the clip list produce undefined results.
The complete list of renderer attributes is listed in the Renderer Attributes Table.
For an overview about Renderers, see General Information. For a list of all Renderer functions and related topics, see Rendering.
