Pretend you have a rubber stamp that says "PAID". Strip the rubber part off of it and glue it to a rolling pin. Ink the stamp and roll it onto a *** of paper. The image is now slightly elongated because it is stretched across the roller so you have to make a new stamp to fix the problem. How much should the image on the new stamp be compressed to compensate for the distortion?



var
f: Extended; // compression_factor;
r: Extended; // radius of the roller
t: Extended; // thickness of strip
begin
...
f := r/(r + t);
...
end;
