NAME
mlib_ImageDivAlpha_Fp - alpha channel division
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDivAlpha_Fp(mlib_image *dst, const mlib_image *src, mlib_s32 cmask);
DESCRIPTION
The mlib_ImageDivAlpha_Fp() function divides floating-point color channels by the alpha channel on a pixel-by-pixel basis. It uses the following equation: dst[x][y][c] = src[x][y][c] / src[x][y][a] where c and a are the indices for the color channels and the alpha channel, respectively, so c != a. The operation follows the IEEE-754 standard.
PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. cmask Channel mask to indicate the alpha channel. Each bit of the mask represents a channel in the image. The channel correspond- ing to the 1 bit of cmask is the alpha channel.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
