[sane-devel] Problems with AutoStep.

[Michael Chapman]

Don't know if this is a bug, or just abuse by the user.

I was scanning in a series of images and giving each one a filename 'by hand'.
The filenames were purely numeric, and all ten digits. (Yep, I was scanning 
bookcovers and filing them by ISBNs!)

Problem 1:
	File names beginning with 0 are truncated to nine digits.
	Setting STEP to "0" does not cure this.

Problem 2:
	I started out leaving STEP at 1 (I was afterall re-entering a new file name 
for each scan, so was not worried about what xSane thought the next one 
should be.)
	I then had an underrun error message for the step counter. 
	That did not worry me, but subsequently everytime I entered a new file name 
xSane erased it and replaced it by 2147483647.png (that is [2^31 - 1].png, I 
think).
	Setting STEP to 0 would not deter it.
	(Rather than restrating xSane, I changed file naming strategy to 
1234567890isbn.png.)

Both (that is truncating a filename and not being able to break out of an 
increment error even when increment is switched off) strike me as 'errors', 
albeit errors of (a) a relatively minor nature and (b) in 'exotic' 
circumstances.

PS Having used autoincrement for scanning several hundred other images in one 
series (and not having had it on my old non-Sane scanner) I do appreciate its 
definite merits!  MC
