NAME

6       sane-pieusb  -  SANE  backend  for  USB-connected  PIE  PowerSlide  and

DESCRIPTION

11       The sane-pieusb library implements a SANE  (Scanner  Access  Now  Easy)
12       backend  that  provides  access to USB-connected PIE and Reflecta slide
13       scanners.
14       At present, the following scanners should work with this backend:

MULTIPLE SLIDES

31       Support for multiple slide scanners (like the  PowerSlide  or  DigitDia
32       series)  is  done by auto-advancing ('Advance slide' setting) the slide
33       after each scan.
34
35       However, for best results, it is recommended to do a preview for  every
36       slide  since  this sets gamma, brightness, and contrast to optimal val‐
37       ues.
38
39       Attention: SANE does not have an automatic landscape/portrait detection
40       and  re-orientation  when scanning multiple slides. You have to put all
41       slides into one orientation first !

DIRT REMOVAL

45       If available, pieusb supports infrared scans  for  dirt  detection  and
46       removal. This must be enabled via the 'Clean image' setting.

KNOWN PROBLEMS

50       The  pieusb backend supports dirt removal based on infrared scan infor‐
51       mation. Since SANE does not provide  post-processing  in  the  backend,
52       pieusb  does  the scanning and dirt removal during the setup phase. The
53       'scan' phase is only used to transfer the completed  image.   Therefore
54       pieusb  does  not  multi-thread  making  a  typical  frontend appear as
55       'blocked'. Also cancel requests are only honored between scans.

ENVIRONMENT

59       SANE_DEBUG_PIEUSB
60              If the library was compiled with  debug  support  enabled,  this
61              environment  variable controls the debug level for this backend.
62              E.g., a value of 128 requests all debug output  to  be  printed.
63              Smaller levels reduce verbosity.
