[sane-devel] Canon FS4000: image data is sensor data, not RGB?

2004-06-18 Thread Ulrich Deiters
Do you receive 3 * 2 bytes per pixel? The FS2710S also produces 2 bytes, of which 12 bit are significant, in the order RRGGBB. The Canon-SCSI backend contains some portions that convert these raw data to the usual 8 bit representation. Perhaps this code can be modified to fit your case. Regards,

Sorry, ignore this post. It's not raw data as I can now see an image with different scanning parameters. - I am making good progress reverse-engineering the SCSI protocol for this film scanner. I now have a short test program in C that scans

I am making good progress reverse-engineering the SCSI protocol for this film scanner. I now have a short test program in C that scans film and I now have the challenge of decoding the image data returned. It appears to be raw sensor data. I don't have experience with many other scanners: is this t
