Manipulación de dos imágenes para realizar un montaje, usando código en Java

El código implementado nos indica que se procede a mezclar dos imágenes una como (background), imagen de fondo y la otra imagen (foreground)para ser montada sobre la primera.

La imagen background es multiplicada por un número alpha, la imagen foreground en primera instancia es duplicada y luego multiplicada por el número alpha con lo cual la imagen original (background no se modificará), dando como resultado una mezcla de las dos imágenes citadas.

A continuación se inserta el código.

import ij.ImagePlus;

import ij.gui.GenericDialog;
import java.awt.*;

}

public void run(ImageProcessor bgIp) {

if(runDialog()){
ImageProcessor fgIp=fgIm.getProcessor().convertToByte(false);
fgIp = fgIp.duplicate();
fgIp.multiply(1-alpha);
bgIp.multiply(alpha);
bgIp.copyBits(fgIp, 0, 0, Blitter.ADD);
}
}

boolean runDialog(){
int[] windowList = WindowManager.getIDList();
if (windowList == null){
IJ.noImage();
return false;
}
String[] windowTitles = new String[windowList.length];
for(int i = 0; i < windowList.length; i++)
{

if (im == null)
windowTitles[i] = "untitled";
else

}
