virtual L_INT LVectorBase::SetOrigin(pOrigin=NULL)

Sets the new origin for the class object's associated vector.


const pVECTORPOINT 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.


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


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 do not your changes will not be saved.
