An interpreter for the programming language Piet (http://www.dangermouse.net/esoteric/piet.html). Currently only runs the program "hi.png".
Run ghc -o piet Main.hs Types.hs.
Assuming the compiled program is called piet, run ./piet <img_name> -cs <codel_size> on a Unix system or
piet.exe <img_name> -cs <codel_size> when you're on Windows. img_name and codel_size respectively
represent the name of the image you'd like to execute and the 'pixel size'. That is, a codel is an enlarged
pixel by a factor of codel_size. The reason Piet uses codels, and not just pixels, is that otherwise Piet
programs would be rather small.
The codels of hi.png are 16x16, so you should run
./piet hi.png -cs 16 or piet.exe hi.png -cs 16.
hi.png was downloaded from http://www.bertnase.de/npiet/.
You may use this code for whatever purpose it may serve.
