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.
