CopyPolygon

The CopyPolygon method returns a copy of this shape's geometric representation, expressed as a polygon.

void CopyPolygon (out ODPolygon copy);

copy

A structure whose fields are set to represent a polygon that describes this shape's geometric representation, or an empty polygon if this shape's geometric representation cannot be represented by a polygon.

DISCUSSION

To check whether the shape's geometric representation can be described by a polygon, call the HasGeometry method. Note that some geometric representations, such as curves, can only be approximated by a polygon.

The polygon returned in the copy output parameter is not owned by this shape; you are allowed to modify it. When you no longer need the polygon, you should deallocate its storage.

EXCEPTIONS

kODErrNoShapeGeometry

This shape has no geometric representation, so it cannot be described as a polygon.

kODErrOutOfMemory

There is not enough memory to copy this shape's geometric representation.
