NAME
mlib_ImageColorRGB2Mono - RGB to monochrome conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageColorRGB2Mono(mlib_image *dst, const mlib_image *src,
const mlib_d64 *weight);
DESCRIPTION
The mlib_ImageColorRGB2Mono() function performs a conversion
from a red/green/blue to a monochromatic image. The sourceimage 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 recom-
mended 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.
