JAME The Java Fractal Platform 6.0.1 (Default branch)
11-25-2008
JAME is a real-time, multi-threaded fractal platform which supports images and animations. The core of JAME is the graphics engine, which supports layers, filters, effects, and alpha composition. JAME creates Mandelbrot and Julia fractals and supports zoom, rotation, and color shifting. JAME has a lot of parameters and supports networked computation. JAME is an OSGi application and can be extended by plug-ins to provide new fractals, formulas, filters, effects, encoders, and more. License: GNU General Public License v3 Changes:|

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
