Hello,
Just recently I bought CanoScan 2700F film scanner (SCSI, canon ackend).
It works fine with the xsane/xscanimage frontends. However, I have troubles to
make it working with the scanimage frontend. Namely, I can not path some
scanner-specific options (--af, --afonce, --highlight).
According to the manual this options are there:
>scanimage -d canon:/dev/sg2 -h
....
?? --highlight 0..255 [255]
??????? Selects what radiance level should be considered "white".
? Focus:
??? --af[=(yes|no)] [yes]
??????? Enable/disable auto focus
??? --afonce[=(yes|no)] [yes]
??????? Do auto focus only once between ejects
When I execute
>scanimage -d canon:/dev/sg2 --resolution 2720 --film-type Slides --highlight
>150 > out.pnm
I get the error message:
> scanimage: unrecognised option --highlight
I have checked the source code of the canon backend and I can not see gross
mistakes. Moreover I can control these options with the xsane GUI.
Please give me a hint where should I look to find a solution of the problem.
Thank you in advance,
Best regards,
Myroslav
