Mr. Huang,
I have a question I was hoping you might help with. It actually has nothing to do with physics, but I'm in the process of coding a neural network that can read 'hand'-written (or rather, mouse-written) characters. Ironically, while creating a neural network was no problem, I couldn't figure out how to do something you did in the applet up there. I was wondering how you managed to detect the colour of a given pixel.

If you could either point me in the right direction, or even better, if you'd be willing to send the source code, I'd be greatly appreciative. Thanks!

The source code are included in the ZIP file you will received if you click DOWNLOAD APPLET FILES FOR OFFLINE USE button.
However, there are all written many years ago with JDK1.0.2
