Good catch. My explanation was not quite complete.
If you try the help with --source="Transparency Unit", you should see slightly different lists of --x-resolution and y-resolution values. The list of --resolution values is the intersection of these lists and those above.

Xsane is no doubt wonderfully competent, but far too complicated for casual use. But I am having a problem with Simple Scan, in that I can't seem to get selected resolutions to have any effect. A typical A4 mainly-text document I am playing with, ends up as: 165K when scanned & saved as text pdf at 75/150/300 or 600dpi... 1.5MB when scanned & saved as text jpg at 75-600dpi 2.2MB when scanned & saved as photo pdf or jpg at 75-600dpi. My Epson V200 scanner allows normal resolution selection with Xsane or with Epson's iscan application. Thanks for any suggestions!" - unquote. I started that thread in December 2010 & still have the same problem today. As a summary - the resolution control has absolutely no effect on the results. No error messages (unless I try 2400dpi) & nothing in simple-scan --debug >simple-scan.log I now have Simple Scan 2.32.0.1-0Ubuntu2 in Ubuntu 11.04. The scanner is an Epson Perfection V200 Photo & has normal resolution selection in XSane & Iscan. Thanks!
