Detailed Description

Describes a 'path geometry' object in the SVG rendering backend, i.e. a graphical object composed of lines, Bezier curves and elliptical arcs, that can be stroked and filled. The rendering backend maintains an object implementing this interface for each rendering engine-native path geometry object.

An engine-native path geometry object will be informed of changes in a path geometry's description with a call to its nsISVGRendererPathGeometry::update() method with an OR-ed combination of the UPDATEMASK_* constants defined in this interface (and its base-interface).

• void constructPath (in nsISVGRendererPathBuilder pathBuilder)

• const unsigned short HITTEST_MASK_FILL = 0x0001
• const unsigned short HITTEST_MASK_STROKE = 0x0002
• readonly attribute unsigned
