LVectorBase::GetObjectParallelogram

#include "ltwrappr.h"

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

pVECTORPOINT pMin;	/* pointer to a vector point */
pVECTORPOINT pMax;	/* pointer to a vector point */
L_UINT32 dwFlags;	/* 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	Flag that indicates which parallelogram to use when updating the pMin and pMax parameters. Possible values are:
	Value	Meaning
	0	pMin and pMax will be updated with the parallelogram containing all objects within the vector handle.
	VECTOR_FLAGS_SELECTED_ONLY	pMin and pMax will be updated with the parallelogram containing all selected objects within the vector handle.
	VECTOR_FLAGS_TRANSFORMED	Apply current transformation on pMin and pMax before returning.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

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

Example

//Example15
L_VOID Example15(HWND hWnd, LVectorBase *pVector)
{
   //This example obtains drawing physical extents
   VECTORPOINT LeftTop, RightBottom;
   POINT LeftTop2D, RightBottom2D;

   // Get drawing logical extents
   pVector->GetObjectParallelogram(&LeftTop, &RightBottom);

   // Convert to physical to get the rect where the drawing will painted
   pVector->LogicalToPhysical(&LeftTop2D, &LeftTop );
   pVector->LogicalToPhysical( &RightBottom2D, &RightBottom );
