LContainer::GetScalar

#include "Ltwrappr.h"

L_INT LContainer::GetScalar (pvptScalarNum, pvptScalarDen)

pVECTORPOINT pvptScalarNum;	/* pointer to a structure */
pVECTORPOINT pvptScalarDen;	/* pointer to a structure */

Gets the current container coordinates scaling values.

Parameter	Description
pvptScalarNum	Pointer to VECTORPOINT structure to be updated with the numerator of the scaling factors for the x, y and z directions.
pvptScalarDen	Pointer to VECTORPOINT structure to be updated with the denominator of the scaling factors for the x, y and z directions.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
