NAME
       mlib_ImageColorRGB2Mono_Fp - RGB to monochrome conversion

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorRGB2Mono_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *weight);

DESCRIPTION
       The  mlib_ImageColorRGB2Mono_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] = weight[0]*src[x][y][0] +
		      weight[1]*src[x][y][1] +
		      weight[2]*src[x][y][2]

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       weight	       Array of three blending coefficients. It is recommended that these sum to 1.0, but it is not required.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
