Converts the values from a specified unit to a point unit type. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
#include "ltvkrn.h"
L_LVKRN_API L_INT L_VecConvertPointFromUnit(pVector, pptDst, pptSrc, pUnitToUse)
Pointer to a vector handle.
Pointer to VECTORPOINT structure to be updated with the converted values.
Pointer to VECTORPOINT structure that contains the source values to be converted.
Pointer to the VECTORUNIT structure that contains the unit types from which the values are converted.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
1 | An error occurred. Refer to Return Codes. |
To convert values from point units to other unit types, call the L_VecConvertPointToUnit function.
To change or retrieve the currently used unit type in the vector toolkit, call the L_VecSetUnit or L_VecGetUnit function.
This example converts a unit used in vector toolkit to point unit.
