sane-pieusb(5) SANE Scanner Access Now Easy sane-pieusb(5) NAME sane-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 se- ries) 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 values. 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, sane-pieusb supports infrared scans for dirt detection and removal. This must be enabled via the 'Clean image' setting. KNOWN PROBLEMS The sane-pieusb backend supports dirt removal based on infrared scan infor- mation. Since SANE does not provide post-processing in the backend, sane-pieusb does the scanning and dirt removal during the setup phase. The 'scan' phase is only used to transfer the completed image. Therefore sane-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 envi- ronment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller lev- els reduce verbosity. level debug output ------- ------------------------------ 0 nothing 1 errors 2 warnings & minor errors 5 additional information 7 SANE api calls 9 backend functions 11 scanner functions 13 usb functions 15 image buffer functions FILES /usr/local/etc/sane.d/pieusb.conf The backend configuration file /usr/local/lib/sane/libsane-pieusb.a The static library implementing this backend. /usr/local/lib/sane/libsane-pieusb.so The shared library implementing this backend (present on systems that support dynamic loading).
