Python will do very nicely; it's installed by default and the command line is 'just there'. I strongly recommend it as a grievously underestimated language. A good place to get started is at O'Reilly: http://www.onlamp.com/python/ You'll need to include a graphics manipulation library. I haven't used it in anger, but the Python Image Library: http://www.pythonware.com/products/pil/index.htm certainly does what you need, according to the online manual (see the getpixel method)!
