LVectorBase::ConvertPointToUnit

#include "ltwrappr.h"

virtual L_INT LVectorBase::ConvertPointToUnit(pptDst, pptSrc,UnitToUse)

pVECTORPOINT pptDst;	/* pointer to a VECTORPOINT structure */
const pVECTORPOINT pptSrc;	/* pointer to a VECTORPOINT structure */
pVECTORUNIT UnitToUse;	/* pointer to a VECTORUNIT structure */

Converts the values from point units to other unit types. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
ptDst	Pointer to VECTORPOINT structure to be updated with the converted values.
ptSrc	Pointer to VECTORPOINT structure that contains the source values to be converted.
pUnitToUse	Pointer to the VECTORUNIT structure that contains unit types to which the values are converted.

Returns

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

Comments

To convert values from point units to other unit types, call the LVectorBase::ConvertPointFromUnit function.

To change or retrieve the currently used unit type in the vector toolkit, call the LVectorBase::SetUnit or LVectorBase::GetUnit function.
