Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write PNM image data to
standard output.

-d, --device-name=DEVICE   use a given scanner device (e.g. hp:/dev/scanner)
    --format=pnm|tiff      file format of output file
-i, --icc-profile=PROFILE  include this ICC profile into TIFF file
-L, --list-devices         show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
                           can be specified: %d (device name), %v (vendor),
                           %m (model), %t (type), and %i (index number)
-b, --batch[=FORMAT]       working in batch mode, FORMAT is `out%d.pnm' or
                           `out%d.tif' by default depending on --format
    --batch-start=#        page number to start naming files with
    --batch-count=#        how many pages to scan in batch mode
    --batch-increment=#    increase number in filename by an amount of #
    --batch-double         increment page number by two for 2sided originals
                           being scanned in a single sided scanner
    --batch-prompt         ask for pressing a key before scanning a page
    --accept-md5-only      only accept authorization requests using md5
-p, --progress             print progress messages
-n, --dont-scan            only set options, don't actually scan
-T, --test                 test backend thoroughly
-h, --help                 display this help message and exit
-v, --verbose              give even more status messages
-B, --buffer-size          change default input buffersize
-V, --version              print version information

Options specific to device `plustek:libusb:001:002':
  Scan Mode:
    --mode Lineart|Gray|Color [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --depth 8|16 [8]
        Number of bits per sample, typical values are 1 for "line-art" and 8
        for multibit scans.
    --source Normal|Transparency|Negative [inactive]
        Selects the scan source (such as a document-feeder).
    --resolution 50..2400dpi [50]
        Sets the resolution of the scanned image.
    --preview[=(yes|no)] [no]
        Request a preview-quality scan.
  Geometry:
    -l 0..215mm [0]
        Top-left x position of scan area.
    -t 0..297mm [0]
        Top-left y position of scan area.
    -x 0..215mm [103]
        Width of scan-area.
    -y 0..297mm [76.21]
        Height of scan-area.
  Enhancement:
    --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.
    --custom-gamma[=(yes|no)] [no]
        Determines whether a builtin or a custom gamma-table should be used.
    --gamma-table 0..255,... [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..255,... [inactive]
        Gamma-correction table for the red band.
    --green-gamma-table 0..255,... [inactive]
        Gamma-correction table for the green band.
    --blue-gamma-table 0..255,... [inactive]
        Gamma-correction table for the blue band.
  Device-Settings:
    --lamp-switch[=(yes|no)] [no]
