/* flag that indicates which parallelogram to get*/ |
Gets the parallelogram that contains the specified object(s).
Parameter |
Description |
|
pMin |
Pointer to a VECTORPOINT structure to be updated with the minimum point of the bounding parallelogram of the specified object. |
|
pMax |
Pointer to a VECTORPOINT structure to be updated with the maximum point of the bounding parallelogram of the specified object. |
|
dwFlags |
