[sane-devel] xsane: page counts and ADF

I have some comments on xsane about page counts and about ADF:

If you're using a flatbed scanner and in the main scanning window you 
change the number of scan pages to a number, for example 30, and you 
start the scan, xsane is pretty much unstoppable (seems to be a bug).  
If you press cancel, it cancels the single page that it is scanning at 
that time, but it keeps on trying to scan the other pages, so you end up 
having to press cancel 30 times to get out of it.  It also doesn't give 
you opportunity to put the next page in the scanner.

So with flatbed scanning, does it really make sense to be able to set 
the number of scans???

If you're using a scanner with automatic document feeding (ADF), if you 
don't set the number of pages to some high number, and you leave the 
number of pages at 1, then even though you put 10 pieces of paper in the 
scanner and click scan, it will scan the first page and then feed all 
the others through, ignoring them, because of the page limit.

Also, having to remember to set the number of pages to some high number 
whenever you start an ADF scan is a bit frustrating from a user 
perspective, because it is natural for the user to expect the scanner to 
scan all the pages they put in.

So with ADF scanning, does it really make sense to be able to set the 
number of scans?  The user would normally put the pages in the scanner 
that they want to scan and expect it to scan them all.


I think it would be a good idea for xsane to at least have a user 
preference to automatically determine the number of pages to scan, 1 for 
flatbed mode, and unlimited for ADF mode, and when that option is 
selected, leave the ability to select the number of pages off the user
