L_VecConvertPointToUnit

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecConvertPointToUnit(pVector, pptDst, pptSrc, pUnitToUse)

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

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

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.

const pVECTORUNIT pUnitToUse

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

Returns

Comments

To convert values from point units to other unit types, call the L_VecConvertPointFromUnit function.

To change or retrive the currently used unit type in the vector toolkit, call the L_VecSetUnit or L_VecGetUnit function.
