NAME¶
sane-teco3 - SANE backend for TECO / RELISYS scanners
DESCRIPTION¶
The
sane-teco3 library implements a SANE (Scanner Access Now Easy)
backend that provides access to some TECO SCSI flatbed scanners. This backend
should be considered
alpha-quality software! TECO scanners are sold
under various brands like RELYSIS, PIOTECH, TRUST. This backend may or may not
support yours.
The scanners that should work with this backend are:
Vendor Model TECO model status
--------------------------- ---------- ----------
Relisys Scorpio VM3552 tested
Plustek OpticPro 2400SP VM3552 untested
PIOTECH Splendeur 3024 VM3552 tested
Trust Imagery 2400 SP VM3552 tested
Trust Imagery 4800 SP+ VM3552 tested
Trust Imagery 9600 SP VM3552 untested
The TECO VM number can usually be found at the back of the scanner. It is also
part of the FCC ID.
The options the backend supports can either be selected through command line
options to programs like scanimage or through GUI elements in xscanimage or
xsane.
If you have any success with a scanner not listed here, or if you have any
strange behavior, please report to the backend maintainer or to the SANE
mailing list.
Valid command line options and their syntax can be listed by using
scanimage --help -d teco3
- Scan Mode
-
- --mode
- selects the basic mode of operation of the scanner valid choices are
Black & White , Grayscale and Color The Black
& White mode is black and white only (1 bit). Grayscale will produce
256 levels of gray (8 bits). Color will produce a 24 bits color image.
- --resolution
- selects the resolution for a scan. The scanner can do all resolutions
between 1 and 1200, in increments of 1.
- Geometry options
-
- -l -t -x -y
- control the scan area: -l sets the top left x coordinate, -t the top left
y coordinate, -x selects the width and -y the height of the scan area. All
parameters are specified in millimeters by default.
- Enhancement options
-
- --custom-gamma
- (color mode only) allows the user to specify a gamma table (see the next 3
parameters).
- --red-gamma-table
- (color mode only) can be used to download a user defined gamma table for
the red channel. The table must be 1024 bytes long.
- --green-gamma-table
- (color mode only) can be used to download a user defined gamma table for
the green channel. The table must be 1024 bytes long.
- --blue-gamma-table
- (color mode only) can be used to download a user defined gamma table for
the blue channel. The table must be 1024 bytes long.
- --preview
- requests a preview scan. The resolution used for that scan is 22 dpi and
the scan area is the maximum allowed. The scan mode is user selected. The
default is "no".
CONFIGURATION FILE¶
The configuration file /etc/sane.d/teco3.conf supports only one information: the
device name to use (eg /dev/scanner).
FILES¶
- /usr/lib/arch_triplet/sane/libsane-teco3.a
- The static library implementing this backend.
- /usr/lib/arch_triplet/sane/libsane-teco3.so
- The shared library implementing this backend (present on systems that
support dynamic loading).
ENVIRONMENT¶
- SANE_DEBUG_TECO3
- 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.
LIMITATIONS¶
The windows TWAIN driver has many more options than this SANE backend. However
they are only software adjustments. This backend only implements what the
scanner can support.
BUGS¶
Not much.
