[sane-devel] Canon FS4000 support - any work lately?

2004-05-29 Thread Dave Burns
I'm interested in reverse-engineering this scanner. I've looked over the support page on the SANE site and I see there were some requests for info by Eric Bachard from this list last August. I emailed him but no reply hence my mail to the whole list. I've figured out how to get logs from Canon's o

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

2004-06-17 Thread Dave Burns
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

2004-07-02 Thread Dave Burns
I am about to throw this scanner away because I don't need it anymore and the $20 it could bring me on eBay isn't worth the trouble. Before I do, I thought I would offer it to anyone on this list who might want it. It's about 5 years old, does about 600dpi, has a SCSI interface (no USB option) and,

2004-07-21 Thread Dave Burns
Some of you are lucky enough to get developer docs from a manufacturer so that writing a driver isn't too hard. I'm working on the Canon FS4000 film scanner and, although I haven't tried, I've heard Canon is tough to get docs from. So, I'd like to get as far as I can before having to sign an NDA wi

I've posted a page with my latest code for the FS4000: http://www.burnsorama.com/fs4000/ The code on this page is not a SANE back-end. It's still a collection of test programs. I have no Linux box but, although the code was written on Windows with VC++, it's ANSI C and should build anywhe
