Functions

Directly Manipulating a Shape's Geometry

This section describes the functions you use to directly manipulate the geometry of a shape object. Unlike most calls to QuickDraw GX objects, these functions give you direct access to the data of a geometry--in QuickDraw GX memory--without regard to the shape object it is part of. You typically call the functions in this order:

• GXLockShape
• GXGetShapeStructure
• GXUnlockShape
• GXChangedShape
