well, i have spent some time looking, and i would call the fujitsu sp300,=
=20
600, jr, and 15c all beta.
i say this because i find 3 major differences between the avision backend=
=20
and the sp15c one.
1. avision backend does not support 4 bit grayscale
2. the fcpa scanpartner scanners have more limited possible resolutions
3. the avision driver does not support independent x/y resolution
output using sp15c backend:
Options specific to device `sp15c':
Scan Mode:
--source ADF|FB [ADF]
Selects the scan source (such as a document-feeder).
--mode Lineart|Halftone|4-bit Gray|8-bit Gray|Color [Lineart]
Selects the scan mode (e.g., lineart,monochrome, or color).
--resolution 0|60|75|80|100|120|150|200|240|300|600dpi [200]
Sets the horizontal resolution of the scanned image.
--y-resolution 0|60|75|80|100|120|150|200|240|300|600dpi [200]
Sets the vertical resolution of the scanned image.
Geometry:
-l 0..216mm (in steps of 1.52588e-05) [0]
Top-left x position of scan area.
-t 0..356mm (in steps of 1.52588e-05) [0]
Top-left y position of scan area.
-x 0..216mm (in steps of 1.52588e-05) [215.47]
Width of scan-area.
-y 0..356mm (in steps of 1.52588e-05) [279.364]
Height of scan-area.
Enhancement:
--threshold 0..255 (in steps of 4) [128]
Select minimum-brightness to get a white point
Advanced:
output using avision:
Options specific to device `avision':
Scan mode:
--mode Line Art|Dithered|Gray|Color [Color]
Selects the scan mode (e.g., lineart,monochrome, or color).
--resolution 50..300dpi (in steps of 10) [300]
Sets the resolution of the scanned image.
--speed 0..4 (in steps of 1) [inactive]
Determines the speed at which the scan proceeds.
--preview[=3D(yes|no)] [no]
Request a preview-quality scan.
Geometry:
-l 0..215mm [0]
Top-left x position of scan area.
-t 0..295mm [0]
Top-left y position of scan area.
-x 0..215mm [215]
Width of scan-area.
-y 0..295mm [295]
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.
--quality-scan[=3D(yes|no)] [yes]
Turn on quality scanning (slower but better).
--quality-cal[=3D(yes|no)] [yes]
Do a quality white-calibration
--transparency[=3D(yes|no)] [inactive]
Switch transparency mode on. Which mainly switches the scanner=20
lamp
off. (Hint: This can also be used to switch the scanner lamp off=20
when
you don't use the scanner in the next time. Simply enable this=20
option
and perform a preview.)
--adf[=3D(yes|no)] [no]
This option enables the Automatic-Docuement-Feeder of the scanner.
This allows you to scan multiple pages manually or automatically.
--gamma-table 0..255,...
Gamma-correction table. In color mode this option equally affects=
=20
the
red, green, and blue channels simultaneously (i.e., it is an=20
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.
--frame 0..0 [inactive]
Selects the number of the frame to scan
i have not tried all the options of the avision backend to see if they=20
work yet.
