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.

L_INT VecGetOriginExample(pVECTORHANDLE pVector) 
{ 
   L_INT nRet; 
   VECTORPOINT Origin; 
   L_TCHAR     szBuffer[ 80 ]; 
   nRet = L_VecGetOrigin( pVector, &Origin ); 
   if(nRet != SUCCESS) 
      return nRet; 
   _stprintf_s( szBuffer,80, TEXT("%f, %f, %f"), Origin.x, Origin.y, Origin.z ); 
   MessageBox( NULL, szBuffer, TEXT("Origin At"), MB_OK ); 
   return SUCCESS;
