L_LVKRN_API L_INT L_VecConvertPointToUnit(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; |

Converts the values from point units to other unit types. 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 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 L_VecConvertPointFromUnit function.
To change or retrive the currently used unit type in the vector toolkit, call the L_VecSetUnit or L_VecGetUnit function.
