NAME
mlib_ImageChannelSplit - channel split SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageChannelSplit(mlib_image **dsts, const mlib_image *src); DESCRIPTION
The mlib_ImageChannelSplit() function converts a multi-channel image into an array of single-channel images. A0 A1 A2 ... A0 B0 C0 A1 B1 C1 A2 B2 C2 ... ===> B0 B1 B2 ... C0 C1 C2 ... All images must have the same type, same width, and same height. The data type of the images can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. The source image must have the number of channels equal to the number of images in the dsts array. The destination images must be single-channel images. PARAMETERS
The function takes the following arguments: dsts Pointer to an array of single-channel destination images. src Pointer to a multi-channel source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageBlendMulti - blend multiple images SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendMulti(mlib_image *dst, const mlib_image **srcs, const mlib_image **alphas, const mlib_s32 *c, mlib_s32 n); DESCRIPTION
The mlib_ImageBlendMulti() 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
