7.

Be creative! Change x.png however you'd like (you can create your own colors). In order to get full credit, you must change at least three different pixels and add two different colors (besides pure red, green, blue, black, or white) to the image.

image = new SimpleImage("x.png");
image.setZoom(20);


print(image);
