/* 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. |

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 );
