I've started to test the canon-dr backed with my DR-7090C scanner,
with latest snapshot (libsane-canon.so.1.0.22). I'm using xsane
V.0.997 and scanimage V.1.0.21.
ADF Duplex and ADF Front works fine, as does all of the scanner's
supported resolutions, and Color/Grey/Halftone/Lineart.
I'm fortunate that "ADF Front" and "ADF Duplex" is working, but
neither xsane nor scanimage provides a "Flatbed" option. I have
included a list of all scanimage options detected. There is no
flatbed option.
==============
root at borg:/tmp# scanimage --help -d canon_dr:libusb:001:007
Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write image data to
standard output.
Parameters are separated by a blank from single-character options
(e.g.
-d epson) and by a "=" from multi-character options (e.g.
--device-name=epson).
-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), %i (index number),
and
%n (newline)
-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 page number in filename by #
--batch-double increment page number by two, same as
--batch-increment=2
--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 input buffer size (in kB, default
32)
-V, --version print version information
Options specific to device `canon_dr:libusb:001:007':
Standard:
--source ADF Front|ADF Duplex [ADF Front]
Selects the scan source (such as a document-feeder).
--mode Lineart|Halftone|Gray|Color [Lineart]

--resolution 100|150|200|240|300|400|600dpi [600]
Sets the resolution of the scanned image.
Geometry:
-l 0..215.872mm (in steps of 0.0211639) [0]
Top-left x position of scan area.
-t 0..279.364mm (in steps of 0.0211639) [0]
Top-left y position of scan area.
-x 0..215.872mm (in steps of 0.0211639) [215.872]
Width of scan-area.
-y 0..279.364mm (in steps of 0.0211639) [279.364]
Height of scan-area.
--page-width 0..298.158mm (in steps of 0.0211639) [215.872]
Specifies the width of the media. Required for automatic
centering of
sheet-fed scans.
--page-height 0..431.744mm (in steps of 0.0211639) [279.364]
Specifies the height of the media.
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.
--threshold 0..255 (in steps of 1) [90]
Select minimum-brightness to get a white point
Advanced:
--df-thickness[=(yes|no)] [no]
