i try to get a image masked. i tried it several times. always get stuck with the same thing. i guess its very easy...

size(200,200);
background(0,200,0);
PImage img= loadImage("http://processing.org/img/cover/cover_greenberg.jpg");
//image(img,10,10);
int sz= img.pixels.length;
int[] maskArray= new int[sz];
for(int i=0; i< sz; i++) {
 if(img.pixels[sz]==#000000)
   maskArray[i]=255;
 else
   maskArray[i]=0;
}
img.mask(maskArray);
image(img,10,10);

WTF? why an out of bounds?

this will fail since all arrays are zero-based, indices [0,1,.....,array.length-1]:

img.pixels[sz]; // i guess you ment "i", or "sz-1" ...
