const mlib_image *src);
DESCRIPTION
The mlib_ImageColorRGB2CIEMono_Fp() function performs a conversion from
a red/green/blue to a monochromatic image. The source image must be a
three-channel image. The destination image must be a single-channel
image.
It uses the following equation:
dst[x][y][0] = 0.2125*src[x][y][0] +
0.7154*src[x][y][1] +
0.0721*src[x][y][2]
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image.
src Pointer to source image.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
