Parameter |
Description |
ClrHandle |
Handle to an existing color conversion. This handle is obtained by calling the L_ClrInit function. |
pSrc |
Pointer to the buffer holding the input data. |
pDst |
Pointer to the buffer that will hold the converted data. |
nWidth |
Width of pixels to be processed. |
nHeight |
Height of pixels to be processed. |
nInAlign |
Each scanline in the input buffer is a multiple of nInAlign bytes. |
nOutAlign |
Each scan line in the output buffer is a multiple of nOutAlign bytes. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
Conversion is done by setting the active method value specified in the CONVERSION_PARAMS structure when calling L_ClrInit. To change the active method, use L_ClrSetConversionParams. Only methods supported by the initialized converter should be specified.
