Yah, I new I'd get flack about that. The Windows driver does support
"European" sizes, but that would mean twice the number of scans to log
as I had. I thought I would start with the "US" sizes even though in
Canada we are quite familiar with "European" sizes. <span

I do plan to add support for "European" sizes or make the size freely
selectable. I've also been toying with integrating my backend with the
rts88xx external backend, which has a freely selectable size. <br>

I understand that it's a bit of work to find out how the size is
encoded but usually the scanners use pixels at some fixed resolution
(or similar) to set the window.

Currently, I use the size to set the window so having a freely
selectable range wouldn't be much of a stretch. However, the motion of
the scan head is jerky at some sizes so I don't think I have it fully
figured out yet.<br>
