может ли "Бэкэнд"/"программа" цветной режим?
У меня сканирует цветным (hp ScanJet 5370C). Можно запросить дополнительные параметры через --help
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
У меня получилось так:
Options specific to device `avision:libusb:003:002':
Scan mode:
--mode Lineart|Dithered|Gray|12bit Gray|Color|12bit Color [Color]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 80..2400dpi (in steps of 1) [150]
Sets the resolution of the scanned image.
--speed 0..4 (in steps of 1) [0]
Determines the speed at which the scan proceeds.
--preview[=(yes|no)] [no]
Request a preview-quality scan.
--source Normal|ADF Front [Normal]
Selects the scan source (such as a document-feeder).
Geometry:
-l 0..216mm [0]
Top-left x position of scan area.
-t 0..296mm [0]
Top-left y position of scan area.
-x 0..216mm [216]
Width of scan-area.
-y 0..296mm [296]
Height of scan-area.
--overscan-top 0..4mm [0]
The top overscan controls the additional area to scan before the paper
is detected.
--overscan-bottom 0..4mm [0]
The bottom overscan controls the additional area to scan after the
paper end is detected.
--background-lines 0..50pel [inactive]
The background raster controls the additional background lines to scan
before the paper is feed through the scanner.
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.
--quality-scan[=(yes|no)] [yes]
Turn on quality scanning (slower but better).
--quality-cal[=(yes|no)] [yes]
Do a quality white-calibration
--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,...
Gamma-correction table for the red band.
--green-gamma-table 0..255,...
Gamma-correction table for the green band.
--blue-gamma-table 0..255,...
Gamma-correction table for the blue band.
--exposure 0..1000% (in steps of 1) [100]
Manual exposure adjustment.
--infra-red[=(yes|no)] [no]
Enable infra-red scan mode.
--multi-sample[=(yes|no)] [no]
Enable multi-sample scan mode.
Scan mode:
--frame 0..0 [inactive]
Selects the number of the frame to scan
--power-save-time <int> [8995]
Allows control of the scanner's power save timer, dimming or turning
off the light.
--paper-length[=(yes|no)] [inactive]
Newer scanners can utilize this paper length to detect double feeds.
However some others (DM152) can get confused during media flush if it
is set.
--flip-page[=(auto|yes|no)] [inactive]
Tells page-flipping document scanners to flip the paper back to its
original orientation before dropping it in the output tray. Turning
this off might make scanning a little faster if you don't care about
manually flipping the pages afterwards.
гуя не видел
Для PRA-retro GUI недопилен, есть проблемы с udev (автозапуск).
