L_VecGetOrigin

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecGetOrigin(pVector, pOrigin)

const pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORPOINT pOrigin;	/* pointer to a vector point */

Gets the origin point for the specified vector handle.

Parameter	Description
pVector	Pointer to a vector handle.
pOrigin	Pointer to a VECTORPOINT structure to be updated with the origin point.

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 L_VecSetOrigin(pVector, NULL) after adding objects.

The origin point may be set using L_VecSetOrigin.
