Chromakey using 2d arrays

First time posting here, hope I'm formatting this right:

I'm having some trouble writing a chromaKey method that basically takes two images, one with a green screen and the other a background, and makes a new image replacing the green-screen with the background.
After compiling, when I try to run it, I get an ArrayIndexOutofBoundsException on the line:



Can someone point me in the right direction?

Well, the only reason for that would be that either pixels or background.pixels has a length of 0; but since you haven't shown us how those are created, it's impossible to guess why.

My suggestion: StopCoding and write down what you're trying to achieve.

Isn't it funny how there's always time and money enough to do it WRONG?

Thanks for the suggestion Winston, I added in the rest of the code so the method makes sense in context and I'll try looking for what's causing the length issue in the meanwhile.
