LVectorBase::SetParallelogram

Show in webframe

#include "ltwrappr.h"

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

const pVECTORPOINT pMin;	/* pointer to a vector point */
const pVECTORPOINT pMax;	/* pointer to a vector point */

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

Parameter	Description
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.
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

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.
