[Bug 891586] Re: Resolution control not working

 

Same problem here:

Canon CanoScan 9000F
sane-backends 1.0.23
simple-scan 3.2.1/3.4.0

- scanning a document in several resolutions (300, 600, 1200dpi) results in output files of same size, all seems to be scanned at 600dpi
- scanner noise sounds equal (while normally sounds "faster" at 300dpi and much "slowlier" at 1200dpi)
- when saved as PDF, only the 600dpi scan has the correct screen size at 100% scale
- "crop to A4 size" from menu only works correct at 600dpi, when scanning at other resolutions the cropped area is too small/too big

Scanning with xsane and skanlite works correct on all resolutions, so it
seems to be a simple-scan problem.

How can I help to narrow down the issue? I'm willing to make an
reasonable effort to this (within the borders of my knowledge ;-), as
simple-scan is a very helpful tool in daily usage (like document
archiving).

TIA,

/Hannes

  Resolution control not working

  "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!
