TWAIN Sane and Mac OS X Lion

I suggest to continue this discussion in the proper section, that is Mac OS X Lion section. See here:

https://discussions.apple.com/thread/3266330

Package for Lion : http://linuxadmin.info/others/software/backup_macosx/sane/

Original package is from : http://www.ellert.se/twain-sane/ - downloaded, I made some changes.

Working for my scanner ... HP 3570c .. i dont have another scanner to test it.

f.

Unfortunately it does not seem to work for me. Preview works and I get an image, but I cannot select an image type, so it asks for a location, I choose desktop, and then it 'hangs' and returns.

If I select image.tiff or jpg or whatever, it still does not work.

I cannot select scan

So it seems to work 'almost'...

(Mustek / iMac / OSX Lion)

I used the above mentioned Sane-links (for Lion) - see rexxor

ImageCapture - doesn't work

Preview - scanner works (Import from scanner)

I dowloaded Snac - works fine (although limited choices)

MacBook Pro - Lion - CanoScan N670U

Follow up: Preview works but only if I don't click on 'show details'.

If I ask to show details and then scan ... I get a distorted image.

ImageCapture - works too BUT don't ask to 'show details'.

What changes did you make?

I'll test it on my old Canone Lide 30, but I'd like to know what's different first.

If this can help:

I have a canon LIDE 30 scanner and I had the skewed images problems when using Preview. I changed the orientation from 0° (or a blank space) to 360°. I got the images scanned correctly since.

Thank you for sharing this solution!

Hi Guys,

I am facing a strange problem after installing it from http://www.ellert.se/twain-sane/

In the 'Show Details' screen, preview is fine. But there is no option under 'Format'- so I cannot save it!

In 'Hide Details' screen, all I get is a diagonal line!!

Any help..!

Are you working with Mac OS 10.7 Lion ? It would be strange if you succeeded installing TWAIN SANE from the link you quoted because there are 10.6 Snow Leopard packages that Lion usually refuses to install. You must use the rexxor link if you want to install for Lion. By the way, what is your scanner ? Is it supported by the SANE librairies ? Did you try with the SNAC software ?

Thanks for your post. I am answering 1 by 1:

It actually has recent updates which has separate entries for Lion!

By the way, what is your scanner ?

hp 3300c.

Is it supported by the SANE librairies ?

Yes- I was using since SnowLeopard days.

Did you try with the SNAC software ?

Yes- after reinstalling in Lion- but it does not give options to change resolution/ output file type and other finer prints! Now, of course, I can do it using TWAIN-SANE command line- as mentioned by jzomer

I have the same scanner. I just saw the Lion software. I'll try it and give you a return.

Everything works like I mentionned in the 10.7 section of this discussion:

https://discussions.apple.com/thread/3266330

With Image Capture, some dialog boxes of "Show details" window are not avalaible. Just type a name for your file and choose a type and a resolution. Put the "Automatic selection" not activate, unless the scanner would scan separated elements if you choose type "Text". Then choose "Hide details" and scan. It should produce a jpeg file of the entire document.

In the Snac software, you should see on the left the "Scan mode", "Output format", "Depth" and "Resolution" choice boxes. Under that, the "Preview" and "Scan" buttons.

If it does not works, try first to unplug (power and USB) the scanner. Then power it up and plug the USB and retry. If nothing is better, try to reinstall Twain Sane and Snac.

Hi *****,

I have an old Canon LIDE 50 and with TWAIN SANE I was able to get Image Capture to see the scaner. The problem is that the scanned image appears distorted in a 45 degree angle. In the SANE app I get the preview image of the scanned document fine, but once scanned the image is distorted... 😕

Any hints?

Have you tried my solution - see above? I can still use my CanoScan N670U scanner.

Not clear enough? Take a look here:
