Sets the parallelogram of the class object's associated vector handle drawing.
#include "ltwrappr.h"
virtual L_INT LVectorBase::SetParallelogram(pMin, pMax);
Pointer to the minimum parallelogram point. If pMin or pMax is NULL, the toolkit will calculate the values based on the minimum parallelogram needed to hold all the objects inside the vector drawing.
Pointer to the maximum parallelogram point. If pMin or pMax is NULL, the toolkit will calculate the values based on the minimum parallelogram needed to hold all the objects inside the vector drawing.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
After adding objects to a vector handle, the logical size of the image might change, this function will calculate new boundaries of the drawing.
This example Gets the vector parallelogram and then changes it.
