Mondrian Painting Description Language interpreter
MPDL interpreter for Python
MPDL operates on a stack of rectangles and outputs a square image. The stack is initialised with a single rectangle filling the whole image. There are 3 commands:
- v<integer 0-100>: Pop a rectangle and split it vertically at the position given by the argument as percentage, rounded down. Push the left and right rectangles, in this order.
- h<integer 0-100>: Split horizontally. Push the top and bottom rectangles, in this order.
- c<integer 1-4>: Pop a rectangle and paint it a colour:
- 1: white
- 2: red
- 3: blue
- 4: yellow
Rectangles are drawn with a black border.
The sample program:
v25 h71 v93 h50 c4 c1 c1 c2 h71 c3 h44 c1 c1
run with canvas size 256px and border width 3px, outputs
