Re: Should a scanned image under Linux and Windows look similiar?

Thanks for your responses.


I am a naive novice when it comes to scanners and images,


...which was my problem.  When I turned off the "RGB Defaults" so that they 
could be adjusted, the "Autoadjust" feature worked very well.

I recently scanned a bunch of stuff using xsane, and the default settings 
were way too dark; I had to adjust the gamma up to get the images to come 
out looking good. When I tweaked the settings, though, the scans came out 
looking exactly like the original photos.

It looks like your xsane settings are overenhancing the green; you should 
pop into the expanded mode (click on the icon on the left, that looks like 
a tree-tined multicolor fork) and try tweaking the color settings 
individually.

Well, the look the same except the linux one has NO red in it. it's like
it got filtered out some how.

Is it a 3 pass color scanner?

Should a scanned image under Linux and Windows look similiar?

2002-11-21 Thread Larry Cook
I am a naive novice when it comes to scanners and images, so maybe this is a 
ridiculous expectation, but I would think that a scanned image under Linux 
would look fairly close to one scanned under Windows, especially when run on 
the exact same hardware.  Both XSane and the Windows software have default 
scan values that are almost identical.  So why aren't the images almost identical?

Here are the two images:

http://www.totalnetnh.net/~lamb/scan_windows.jpg
http://www.totalnetnh.net/~lamb/scan_linux.jpg

The Windows scan is extremely close to the original photo.

I have purposely omitted h/w and s/w specifics because I want to know if I 
have an unreasonable expectation.

Thanks,
Larry
