(09:08:04) Michael Nagel: hi DemoFreak
(09:08:37) robert_ancell: DemoFreak, welcome
(09:08:43) Michael Nagel: i suggest you (DemoFreak) mention your topic now
(09:09:19) DemoFreak: ok, i think it's shorter if i post the url ;)
(09:09:22) DemoFreak: https://bugs.launchpad.net/simple-scan/+bug/891586/comments/3
(09:09:41) DemoFreak: i'd like to know how i could help to solve this issue
(09:10:22) DemoFreak: i'm no coder, but an rather experienced linux user
(09:10:32) robert_ancell: DemoFreak, great!  The first thing to do is look at the log in ~/.cache/simple-scan - this will tell you all the information that simple-scan got from the scanner
(09:10:51) DemoFreak: so my help would be limited to tests and log-generating ;)
(09:11:04) DemoFreak: ok
(09:11:23) DemoFreak: shall i attach that to this bug?
(09:12:12) robert_ancell: yes please
(09:13:05) robert_ancell: Simple Scan does it's best to match the resolution chosen by the user, but I'm wondering if your scanner is confusing it
(09:13:52) DemoFreak: formerly i own an hp5370c, there was no problem at all (i think)
(09:14:25) robert_ancell: Note that simple-scan --debug is broken (due to a change in glib) so I need to fix it.  But it is the same content as in ~/.cache
(09:14:57) robert_ancell: DemoFreak, are you able to get the log now, then we can have a quick look at it
(09:14:57) DemoFreak: the canon sane backend is rather new, maybe it's a combo out of this quite untested backend and simple-scan
(09:15:02) DemoFreak: mom
(09:15:19) DemoFreak: i have a ~500kb log there
(09:15:36) robert_ancell: it's a quite detailed log :)
(09:15:47) DemoFreak: shall i generate a new log, or will you read through 500kb? ;)
(09:16:01) DemoFreak: ok, will attach now
(09:17:55) DemoFreak: robert_ancell: https://bugs.launchpad.net/simple-scan/+bug/891586/comments/4
(09:20:12) robert_ancell: DemoFreak, thanks.  So the log says your scanner claims to do 75, 150, 300, 600, 1200, 2400, 4800 resolutions
(09:20:26) DemoFreak: yes
(09:20:45) DemoFreak: i tried 300, 600 and 1200
(09:21:37) robert_ancell: I'll have to have another look later, but the log looks ok for now
(09:22:25) Michael Nagel: hmmm :( let's postpone this
(09:22:26) DemoFreak: maybe i'm AFK later, but i'll read the backlog
(09:46:43) DemoFreak: sorry for disturbing again ;-): i've generated 3 single logs with different resolution scans for better comparison. shall i upload the tarball as attachment to the bug?
(09:46:50) robert_ancell: DemoFreak, yes please
(09:47:05) DemoFreak: ok. i'm out for now. cya ;)

Title:
  Resolution control not working

Status in Simple Scan:
  Triaged

Bug description:
  Details in my Ubuntu Forum thread: 
  http://ubuntuforums.org/showthread.php?t=1648771
  Quote:
  "Firstly - congratulations for Simple Scan, which lives up to its name admirably!
  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!
