NAME

       mlib_ImageColorRGB2CIEMono - RGB to monochrome conversion

SYNOPSIS

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

       mlib_status mlib_ImageColorRGB2CIEMono(mlib_image *dst, const mlib_image *src);

DESCRIPTION

       The  mlib_ImageColorRGB2CIEMono() 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.

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.
