Hi All,
After seeing Rob's excellent scanangle chart, it got me off by butt to write a scan-angle calculator. You put in whatever distance you're scanning at, and the desired angle you want to scan at, and it tells you the image size you need. I think it would work best with a square of the ILDA test pattern. I wrote this because all the scan angle charts are for specific distances.
If you find problems or have some ideas to make it better (or you think it sucks), please let me know.
Just unzip it to wherever you want and run it.
Tim
