This program requires an image colormap.jpg to be put on the desktop of the pi. Creating this image involves:
MS paint (or any other tool)
resize the canvas to a ratio of imageheight : imagewidth
paint in pure red or blue (255, 0, 0 or 0, 0, 255)
ctrl A, reduce canvas size to imageheight * imagewidth
save as colormap.jpg, transfer to pi via WinSCP
This program also assumes that a single chain of leds will be folded left and right multiple times to create a grid
https://www.adafruit.com/product/3635 is the LED strip this works with
