mlib_ImageBlendMulti_Fp(3MLIB) mediaLib Library Functions mlib_ImageBlendMulti_Fp(3MLIB) NAME
mlib_ImageBlendMulti_Fp - blend multiple images SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendMulti_Fp(mlib_image *dst, const mlib_image **srcs, const mlib_image **alphas, const mlib_d64 *c, mlib_s32 n); DESCRIPTION
The mlib_ImageBlendMulti_Fp() function blends multiple source images, using multiple alpha images, into a single destination image. All images involved should have the same data type and same size and the source and destination images should have the same number of chan- nels. The alpha images should have either 1 channel or the same number of channels as the sources and destination. A single-channel alpha image would be applied to all channels of the corresponding source image. Single and multi-channel alpha images can be mixed in the same invocation. It uses the following equation: n-1 SUM {alphas[k][x][y][j] * srcs[k][x][y][i]} k=0 dst[x][y][i] = --------------------------------------------- n-1 SUM {alphas[k][x][y][j]} k=0 or n-1 dst[x][y][i] = c[i] if SUM {alphas[k][x][y][j]} = 0 k=0 where j = i for multi-channel alpha images; j = 0 for signle-channel alpha images. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. srcs Pointer to an array of source images. alphas Pointer to an array of alpha images. c Background color. n Number of source images to be blended. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
