#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecGetOrigin(pVector, pOrigin)

Gets the origin point for the specified vector handle.

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

pVECTORPOINT pOrigin

Pointer to a VECTORPOINT structure to be updated with the origin point.

Returns

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.
