Incorporating Style Information Into Shape Geometries
QuickDraw GX requires that shapes used for certain purposes (caps, joins, dashes, patterns, and clips) be in primitive form--that is, their style modifications must be incorporated into their geometries. For example, the GXSetShapeDash function requires that the shape used for dashing be in primitive form; the GXSetShapeCap, GXSetShapeJoin, and GXSetShapePattern functions are similar.
For more information about the primitive form of shapes and for examples of functions that use shapes in their primitive form, see Chapter 3, "Geometric Styles," in this book.
The GXPrimitiveShape function converts a shape to its primitive form, incorporating the modifications made by the shape's style into the shape's geometry.
