NAME
mlib_ImageColorRGB2CIEMono_Fp - RGB to monochrome conversion SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageColorRGB2CIEMono_Fp(mlib_image *dst, 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. ATTRIBUTES

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. ATTRIBUTES
