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 `hp:libusb:001:003':
  Scan Mode:
    --preview[=(yes|no)] [no]
        Request a preview-quality scan.
    --mode Lineart|Halftone|Grayscale|Color [Lineart]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --resolution 12..3200dpi (in steps of 1) [300]
        Sets the resolution of the scanned image.
  Enhancement:
    --brightness -127..127 (in steps of 1) [0]
        Controls the brightness of the acquired image.
    --contrast -127..127 (in steps of 1) [0]
        Controls the contrast of the acquired image.
    --auto-threshold[=(yes|no)] [no]
        Enable automatic determination of threshold for line-art scans.
  Advanced Options:
    --custom-gamma[=(yes|no)] [no]
        Determines whether a builtin or a custom gamma-table should be used.
    --gamma-table 0..255,... (in steps of 1.52588e-05) [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).
    --matrix-type Auto|NTSC Gray|Red|Green|Blue [Auto]
        Set the scanners color matrix.
    --matrix-rgb -3.99219..3.99219,... (in steps of 1.52588e-05) [inactive]
        Custom color matrix.
    --halftone-pattern Coarse|Fine|Bayer|Vertical|Horizontal|Custom [inactive]
        Defines the halftoning (dithering) pattern for scanning halftoned
        images.
    --speed Auto|Slow|Normal|Fast|Extra Fast [Auto]
        Determines the speed at which the scan proceeds.
    --depth 1 [inactive]
        Number of bits per sample, typical values are 1 for "line-art" and 8
        for multibit scans.
    --output-8bit[=(yes|no)] [inactive]
        Use bit depth greater eight internally, but output only eight bits.
    --source Normal|ADF|XPA [Normal]
        Selects the scan source (such as a document-feeder).
    --button-wait[=(yes|no)] [no]
        Wait to scan for front-panel button push.
