NAME
       mlib_ImageColorErrorDiffusion3x3 - true color to indexed color conversion using error diffusion

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

       mlib_status  mlib_ImageColorErrorDiffusion3x3(mlib_image  *dst,	const  mlib_image *src, const mlib_s32 *kernel, mlib_s32 scale, const void
       *colormap);

DESCRIPTION
       The mlib_ImageColorErrorDiffusion3x3() function converts a true color image to a pseudo color image with  the  method  of  error  diffusion
       dithering.  The	source image can be an MLIB_BYTE or MLIB_SHORT image with three or four channels. The destination must be a single-channel
       MLIB_BYTE or MLIB_SHORT image.

       The last parameter, colormap, is an internal data structure for inverse color mapping.  Create it by calling the mlib_ImageColorTrue2Index-
       Init() function.

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination or destination image.

       src	       Pointer to source or source image.

       kernel	       Pointer to the 3x3 error-distribution kernel, in row major order.

       scale	       The scaling factor for kernel to convert the input integer coefficients into floating-point coefficients:

		       floating-point coefficient = integer coefficient * 2**(-scale)

       colormap        Internal data structure for inverse color mapping.

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