#include "ltwrappr.h"

virtual L_INT LVectorBase::GetObjectParallelogram(pMin, pMax, dwFlags=0)

Gets the parallelogram that contains the specified object(s).

Parameters

pVECTORPOINT pMin

Pointer to a VECTORPOINT structure to be updated with the minimum point of the bounding parallelogram of the specified object.

pVECTORPOINT pMax

Pointer to a VECTORPOINT structure to be updated with the maximum point of the bounding parallelogram of the specified object.

L_UINT32 dwFlags

Flag that indicates which parallelogram to use when updating the pMin and pMax parameters. Possible values are:

Returns

Comments

Obtains the bounding parallelogram of a single object, several selected objects, or all objects within the vector handle.
