L_VecConvertPointFromUnit

#include "l_bitmap.h"

L_LVKRN_API L_INT L_VecConvertPointFromUnit(pVector, ptDst, ptSrc, pUnitToUse)

const pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORPOINT pptDst;	/* pointer to a VECTORPOINT structure */
const pVECTORPOINT pptSrc;	/* pointer to a VECTORPOINT structure */
const pVECTORUNIT pUnitToUse;	/* pointer to a VECTORUNIT structure */

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

Parameter	Description
pVector	Pointer to a vector handle.
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 the unit types from 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 L_VecConvertPointToUnit function.

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