sane-pieusb(5) SANE Scanner Access Now Easy sane-pieusb(5)NAMEsane-pieusb - SANE backend for USB-connected PIE PowerSlide and
Reflecta DigitDia/CrystalScan/ProScan slide scanners
DESCRIPTION
The sane-pieusb library implements a SANE (Scanner Access Now Easy)
backend that provides access to USB-connected PIE and Reflecta slide
scanners.
At present, the following scanners should work with this backend:
Model: Status
------------------------- ------
PIE PowerSlide 3600 Untested
PIE PowerSlide 3650 Untested
PIE PowerSlide 4000 Untested
PIE PowerSlide 5000 Untested
Reflecta CrystalScan 7200 Untested
Reflecta ProScan 4000 Untested
Reflecta ProScan 7200 Untested
Reflecta DigitDia 3600 Untested
Reflecta DigitDia 4000 Untested
Reflecta DigitDia 5000 Untested
Reflecta DigitDia 6000 Ok
MULTIPLE SLIDES
Support for multiple slide scanners (like the PowerSlide or DigitDia
series) is done by auto-advancing ('Advance slide' setting) the slide
after each scan.
However, for best results, it is recommended to do a preview for every
slide since this sets gamma, brightness, and contrast to optimal val‐
ues.
Attention: SANE does not have an automatic landscape/portrait detection
and re-orientation when scanning multiple slides. You have to put all
slides into one orientation first !
DIRT REMOVAL
If available, pieusb supports infrared scans for dirt detection and
removal. This must be enabled via the 'Clean image' setting.
KNOWN PROBLEMS
The pieusb backend supports dirt removal based on infrared scan infor‐
mation. Since SANE does not provide post-processing in the backend,
pieusb does the scanning and dirt removal during the setup phase. The
'scan' phase is only used to transfer the completed image. Therefore
pieusb does not multi-thread making a typical frontend appear as
'blocked'. Also cancel requests are only honored between scans.
ENVIRONMENT
SANE_DEBUG_PIEUSB
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend.
E.g., a value of 128 requests all debug output to be printed.
Smaller levels reduce verbosity.
