#include "ltwrappr.h"

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

Converts the values from a specified unit to a point unit type. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

pVECTORPOINT pptDst

Pointer to VECTORPOINT structure to be updated with the converted values.

const pVECTORPOINT pptSrc

Pointer to VECTORPOINT structure that contains the source values to be converted.

pVECTORUNIT UnitToUse

Pointer to the VECTORUNIT structure that contains the unit types from which the values are converted.

Returns

Comments

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

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