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

KNOWN PROBLEMS

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

ENVIRONMENT

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