if you look closely at the url, you can change the output color gradient with color codes and height/width

you can use the awt library in java to do this by creating an Image and getting the Image object exported to a png. but there are potential pitfalls if you are running on a server that has no gui...then you should look into the headless mode and the varying support levels for the awt api in that
