L_VecSetOrigin

Summary

Sets new origin for a vector handle.

Syntax

L_LVKRN_API L_INT L_VecSetOrigin(pVector, pOrigin)

Parameters

pVECTORHANDLE pVector

Pointer to a vector handle.

const pVECTORPOINT 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

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 do not, your changes will not be saved.

Example

This example will recalculate the origin of a vector image.
