L_VecSetOrigin

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecSetOrigin(pVector, pOrigin)

pVECTORHANDLE pVector;

/* pointer to a vector handle */

const pVECTORPOINT pOrigin;

/* pointer to a vector point */

Sets new origin for a vector handle.

Parameter

Description

pVector

Pointer to a vector handle.

pOrigin

Pointer to a VECTORPOINT structure that contains the new origin. If this parameter is NULL, the new origin will be calculated based on the objects currently in the vector handle.

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 may be retrieved using L_VecGetOrigin.

L_VecApplyTransformation must be called to make the new origin take effect; if you dont your changes will not be saved.
