That transformation is in the book? It divides by zero for y == 0. I
have to look.
I'm working on an update. It adds:
r x y w h file (done)
Reads a certain rectangle of a file. This makes crop(1)'s -r option
three lines of rc or /bin/sh:
echo 'r '$1' '$2' '$3' '$4' '$5'
new = old
w '$6 | pico
Simple variables (started)
Undo command u (done)
Use of RGB24 instead of RGBA32 to make the examples work (done)
Using Brdstr instead of Bgetc/Bungetc (this is not working)
