LVectorBase::SetOrigin
#include "ltwrappr.h"
virtual L_INT LVectorBase::SetOrigin(pOrigin=NULL)
const pVECTORPOINT pOrigin; |
/* pointer to a vector point */ |
Sets the new origin for the class object's associated vector.
Parameter |
Description |
pOrigin |
Pointer to a VECTORPOINT structure that contains the new origin. If this parameter is NULL, the new origin will be calculated based on the objects currently in the vector handle. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The origin of a vector drawing may change whenever new objects are added. To insure that the drawing is centered around its origin, call LVectorBase::SetOrigin(NULL) after adding objects.
The origin may be retrieved using LVectorBase::GetOrigin.
LVectorBase::ApplyTransformation must be called to make the new origin take effect; if you dont your changes will not be saved.
