Code:
scanimage -A -d 'genesys:libusb:001:004'
the numbers 001 and 004 can change over time (reboot or usb disconnect), you can use scanimage -L again to find the numbers
This outputs:
Code:
All options specific to device `genesys:libusb:001:004':
Scan Mode:
--mode Color|Gray|Lineart [Gray]
Selects the scan mode (e.g., lineart, monochrome, or color).
--source Flatbed|Transparency Adapter [inactive]
Selects the scan source (such as a document-feeder).
--preview[=(yes|no)] [no]
Request a preview-quality scan.
--depth 8|16 [8]
Number of bits per sample, typical values are 1 for "line-art" and 8
for multibit scans.
--resolution 4800|2400|1200|600|300|200|150|100|75dpi [75]
Sets the resolution of the scanned image.
Geometry:
-l 0..216.07mm [0]
Top-left x position of scan area.
-t 0..299mm [0]
Top-left y position of scan area.
-x 0..216.07mm [216.07]
Width of scan-area.
-y 0..299mm [299]
Height of scan-area.
Enhancement:
--custom-gamma[=(yes|no)] [no]
Determines whether a builtin or a custom gamma-table should be used.
--gamma-table 0..65535,... [inactive]
Gamma-correction table. In color mode this option equally affects the
red, green, and blue channels simultaneously (i.e., it is an intensity
gamma table).
--red-gamma-table 0..65535,... [inactive]
Gamma-correction table for the red band.
--green-gamma-table 0..65535,... [inactive]
Gamma-correction table for the green band.
--blue-gamma-table 0..65535,... [inactive]
Gamma-correction table for the blue band.
--swdeskew[=(yes|no)] [no]
Request backend to rotate skewed pages digitally
--swcrop[=(yes|no)] [no]
Request backend to remove border from pages digitally
--swdespeck[=(yes|no)] [no]
Request backend to remove lone dots digitally
--despeck 1..9 (in steps of 1) [1]
Maximum diameter of lone dots to remove from scan
--swskip 0..100% (in steps of 1) [0]
Request driver to discard pages with low numbers of dark pixels
--swderotate[=(yes|no)] [no]
Request driver to detect and correct 90 degree image rotation
--brightness -100..100 (in steps of 1) [0]
Controls the brightness of the acquired image.
--contrast -100..100 (in steps of 1) [0]
Controls the contrast of the acquired image.
Extras:
--lamp-off-time 0..60 [15]
The lamp will be turned off after the given time (in minutes). A value
of 0 means, that the lamp won't be turned off.
--lamp-off-scan[=(yes|no)] [no]
The lamp will be turned off during scan.
--threshold 0..100% (in steps of 1) [50]
Select minimum-brightness to get a white point
--threshold-curve 0..127 (in steps of 1) [50]
Dynamic threshold curve, from light to dark, normally 50-65
--disable-dynamic-lineart[=(yes|no)] [no]
Disable use of a software adaptive algorithm to generate lineart
relying instead on hardware lineart.
--disable-interpolation[=(yes|no)] [no]
When using high resolutions where the horizontal resolution is smaller
than the vertical resolution this disables horizontal interpolation.
--color-filter Red|Green|Blue [Green]
When using gray or lineart this option selects the used color.
--calibration-file <string> [/home/boris/.sane/canon-lide-100.cal]
Specify the calibration file to use
--expiration-time -1..30000 (in steps of 1) [-2134835368]
Time (in minutes) before a cached calibration expires.A value of 0
means cache is not used used. A negative value means cache never
expires.
