Hello John,
Hello Werner,
Hello Everybody,
Thanks John for your github link it inspired me to write some small scripts
to automate your encoding solution.
Also I noticed that Grops output for line drawing is very intense for the
DL command only draws lines of 10 units and grops then spits out a massive
amount of DL command if you draw a line from one side to the other side of
your page. So I also made a script to do this in 1 DL command.
You can find my solution here

Have a nice evening everybody.
Keep up the good work
Kind regards
Wim Stockman
