NAME
mlib_ImageColorTrue2Index - true color to indexed color using nearest matched LUT entries SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageColorTrue2Index(mlib_image *dst, const mlib_image *src, const void *colormap); DESCRIPTION
The mlib_ImageColorTrue2Index() function converts a true color image to a pseudo color image with the method of finding the nearest matched lookup table entry for each pixel. 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 (which includes the lookup table) for inverse color mapping. Create it by call- ing the mlib_ImageColorTrue2IndexInit() function. PARAMETERS
The function takes the following arguments: dst Pointer to destination or destination image. src Pointer to source or source image. colormap Internal data structure for inverse color mapping. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

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. ATTRIBUTES
