.SH NAME
|
|
sane\-pieusb \- SANE backend for USB-connected PIE PowerSlide and
|
|
Reflecta DigitDia/CrystalScan/ProScan slide scanners
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.B 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:

.SH "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
|
|
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 !
|
|
|
|
.SH "DIRT REMOVAL"
|
|
If available, pieusb supports infrared scans for dirt detection and
|
|
removal. This must be enabled via the 'Clean image' setting.
|
|
|
|
.SH "KNOWN PROBLEMS"
|
|
The pieusb backend supports dirt removal based on infrared scan
|
|
information. 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.
|
|
|
|
.SH "ENVIRONMENT"
|
|
.TP
|
|
.B 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.
