[sane-devel] Multiple Scanner Support
Hi. I'm currently using multiple scanners for a project where I have flowers scanned a few times an hour to make videos of the desiccation process. I'm currently in Germany where I've managed to get three scanners running off of one iBook, but at home I have eight scanners strewn across multiple old computers. My original idea was to have all the scanners running off of one computer, but issues with drivers conflicting with each other in addition to poorly programmed drivers which use over half of the CPU's resources while scanning presented problems. I've been using the included software packages where possible, and VueScan when not. I've experimented a bit with SANE. I was wondering what people thought about the possibility of running multiple scanners off of one computer. Does SANE support this? And I've been using solely PPC Macs running either 10.4 or 10.5 so far. You can find some videos of my project here: http://www.flickr.com/photos/featheredtar/sets/72157611634807864/ Thanks, Joel -- next part -- An HTML attachment was scrubbed...

Thanks. Here I'm using a CanoScan 5600F (the Mac driver of which is kind of unstable, and the shipped program horribly bloated!,) an Epson Perfection V33 (a bad scanner!,) and a CanoScan 3200 (which I'm using with VueScan, it's proven to be very stable.) At home I have another CS 5600F, two CS LiDE 20s, a CS 5000, an Agfa Snapscan e20 and e50, and a really good Epson scanner, the name of which I forget. I could VNC the computer to find out, but I'm on my cell phone data connection right now... The issue of resource hogging isn't common. So far I've only starkly experienced it with the CS 5600Fs. It's unfortunate that such an amazing scanner has to have such a shoddy Mac backend/driver. Hopefully the eventual SANE backend will be better! Similar to your idea, initially I tried running multiple instances of VueScan, but because the specific scanners weren't specified to each instance, they presumably conflicted, causing the different instances to occasionally crash. How would one give explicit device names to each copy? I am very comfortable with OS GUIs, but unfortunately have done almost no programming. - Joel On Thu, Jul 14, 2011 at 2:05 AM, m. allan noah kitno455 at gmail.com wrote: Neat videos!

Hello, an off-topic question On Jul 13 13:55 D. Hugh Redelmeier wrote (excerpt): I want to do what I think is called scan to archive. I have way too many documents on paper and I'd like to capture them and discard the paper. ... I need a format that will still be useful for decades into the future. Right off the bat I would say: Keep the paper. I mean that I cannot imagine a format (perhaps except plain ASCII text) where I am sure as of today that it will stay for decades into the future.

Neat. So far my experience with SANE is using it as a TWAIN plugin for Mac
OSX's Image Capture. The text based commands seem much better than the gaudy
manufacturer supplied GUIs though! Maybe I'll direct my future scanner
purchases to SANE supported scanners. Into which program(s) do I input the
pseudocode?

But PDF/A would created and standardised to long time archive! (To make it more complicated, it exist more than one version of PDF/A.) I think, it would be enough to using a popular format like PDF/A because it will exist some programs to change to the next format in the future. The next problem is to create a *correct* PDF/A. To make sure this, it exist some programs and online checker. It seems to be needed :-( And a last question: I mean, it is enough to made one bit per pixel (lineart) for letters, but it exist examples for color scan in such cases - I don't know why: http://openlibrary.org/books/OL24347298M/Muhammedanisches_Recht_nach_Schafiitischer_Lehre -- Viele Gr??e Werner Holtfreter

No, you re-write the pseudocode in a real programming language :) What
I gave was something kinda like shell, which can be stored in a text
file, made executable, and run directly. Not sure how that works on a
mac...

Allen has been a steadfast contributor to this list of information and advice to scanner users, for which it is entirely appropriate to say Thank you from time to time. Thank you, Allen, for the significant personal effort you contribute to make SANE and this list a valuable resource for many others. With respect to the original poster's question about what operating system you prefer, this is the first time I can recall where you have been discreet, even reticent, to offer an opionion about software. You have every right to reserve comment, of course. Among other possibilities, you may simply seek to avoid a cascade of posts about the perceived advantages or problems of different software platforms. It is possible your discretion on this topic might start a cult among list readers that tries to infer your operating system preferences from clues it claims to find in your posts. I guess that is the price of prominence.
[sane-devel] Multiple Scanner Support
I'm not entirely sure how to respond. First, I very much appreciate the thanks. Performing sane's janitorial duties doesn't usually elicit praise :) Oddly, it was never my intention to be in this position. In 2003, I simply wanted to get a patch into the fujitsu backend, and then leave this list. Obviously that plan failed :) Second, I hesitate to recommend an OS because there are some very dedicated port maintainers on this list. I don't want to put them in a position where they feel they must defend their organization/employer. Third, I am somewhat disturbed at the thought of a cult. But I wonder if I could get them to come and mow my lawn? allan On Thu, Jul 14, 2011 at 12:12 PM, Richard Ryniker ryniker at alum.mit.edu wrote: Allen has been a steadfast contributor to this list of information and advice to scanner users, for which it is entirely appropriate to say Thank you from time to time. ?Thank you, Allen, for the significant personal effort you contribute to make SANE and this list a valuable resource for many others.
