LVectorBase::SetParallelogram

#include "ltwrappr.h"

virtual L_INT LVectorBase::SetParallelogram(pMin, pMax);

Sets the parallelogram of the class object's associated vector handle drawing.

Parameters

const pVECTORPOINT pMin

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.

const pVECTORPOINT pMax

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.

Returns

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

Comments

After adding objects to a vector handle, the logical size of the image might change, this function will calculate new boundaries of the drawing.
