  Review: Linux vs. Windows 98 Scanning
LinuxMedNews Posted by I. Valdes on Monday May 21, 2001 @ 11:55 PM
from the comparisons dept.
Updated 5/24/01: Read in the comments section on sharpening algorithms. I finally broke down and shelled out some dollars for a scanner, an Epson Perfection 1240U Photo in order to add a few pics to LinuxMedNews.com. Having plunked down my money I thought I might as well do a side by side test of the scanner on Linux and Windows. I was prepared to be disappointed in Linux due to previous experience with sound card and video configuration. Read on to see what happened. Digg this article

The Epson Perfection 1240U Photo I bought was $217 from Computers4Sure. It is a USB device which includes a transparency adapter for scanning negatives and other films. The scans were done on the same machine dual-booted to Windows 98SE and RedHat Linux 7.1 using the defaults for all software.

Installation for both Linux and Windows receive a B+. It came down to two issues: both had annoying installation problems but Windows was somewhat easier to install. This was negated by the bundled manufacturers software NOT being as good as Linux! Xsane ("Scanner Access Now Easy", the Linux scanner graphic user interface program) was more cleanly laid out and better suited to its purpose than the manufacturers bundled scanning software. Xsane supported every feature of the scanner, including the transparency unit. Along with GIMP, the combination was quite powerful. What's more, I didn't have to install it as RedHat 7.1 already had placed it on my machine. A major minus is that I had to surf the web to find out that xsane was the scanning software for Linux and I had to find and enter some magic incantations and edit /etc/sane.d/epson.conf to get it to work. Moreover, I found the included Adobe(TM) PhotoDeluxe(tm) software bundled on Windows to be clumsy, non-standard and had an excessive number of screen changes to get tasks done. It seemed like more of an advertisement than 'serious' software and it became intrusive. The FilmFactory photo organizing crippleware, er, software was also a disappointment.

After paying $217 for the scanner and bundled software, I found that you had to fork over $40 more to use the full version of FilmFactory which was virtually unusable in its 'free' bundled form. Not good. While one of its GNOME counterparts gAlbum looks somewhat deserted on Sourceforge it provided a fair amount of functionality without the absurd limits that the out-of-the-box FilmFactory had: 5 'roll' limit, and file format export limited to GIF and BMP. That is unless you wished to shell out $40 for the full version.

I did not notice any appreciable difference between scanner speed on Windows and Linux. The scanned in photos both became blocky with greater than 200% Zoom of a picture. However, picture colors were more accurate with Linux.

This picture was scanned using the Epson bundled scanner software on Windows, while this one was scanned using the xsane 0.62 software on RedHat Linux 7.1 at identical 200 dpi originally TIF file format, but converted to JPEG for display on the web. I've put them in a large size so that a close comparison can be done and I used default settings on all software for an out-of-box experience. The flesh tones and colors are less vibrant on the Linux scanned picture, however, the Linux scan is much closer to what the actual photograph looks like. The blue chair is too blue and the flesh tone is more colorful than the actual photo in the Windows scan. Update 5/24/01: a reader has found that the Windows scan has been put through a 'sharpening' algorithm that is present in GIMP, but not default. Sharpening with GIMP results in a sharper scan on Linux which you can see here.

In conclusion, which is better? I call it a tie. Once the hardware was installed, scanning software on Linux was better than Windows. Linux lost a few points for having to figure out which software did scanning, and having to edit a configuration file. But, it gained it back with the 'bundled' xsane software for Linux which was more suited to task than its equivalents on Windows. Scanned picture colors were more accurate on Linux than Windows. Finally, you don't have to put up with company logo's and splash screens at every turn with the bundled Windows software which seemed to compromise the user interface.

    in the world of linux scanning software there is kooka which is part of KDE2. it uses the sane backend like xmame but is integrated with the KDE desktop. in fact, from the KOffice apps you can import an image from your scanner via kooka simply by select an option in the menu bar. i've been nothing but happy with sane+kooka using my USB HP scanner. oh, and for thumbnail viewing pixie by mosfet (also kde2) is absolutely wonderful for viewing large groups of thumbnails and even doing minor editing on them (cropping, etc...) just thought i'd give the KDE perspective of this part of computing life as the author did a good job of showing the Gnome side. (nice write up btw!)

    Perhaps its due to the post-processing, but I noticed that the filesize of the windoze generated picture is about 50% bigger than the linux one... (138K vs. 89K)

    Well, I set up the same scanner on Mandrake 7.2. and i have to agree, the install was not easy. but i did it. and it works great. i spent time looking into which scanners were supported well by Sane, and the Epson looked a good match. I'd suggest the same policy to anyone else looking for a scanner for linux (e.g. just because umax is a decent cheap brand under windoze doesn't mean the scanner will work well with linux. they have a proprietary interface which is not open. shame on umax). anyway, like i said, it works just great. and it was pretty much the last thing i had to get right to switch fully to linux. and i'm very happy to have done so!!! cheers, Andrew

    Windows software used a "sharpen" filter
    by echo on Thursday May 24, 2001 @ 02:14 PM
    I've sort of got proof that the Windows software used a "Sharpen" filter... The picture below is the linux generated picture above, ran through the gimp's "sharpen" filter, and finely adjusted to match the Windows scan above. You'll notice, only the colors are off now. I believe that scan manufacturers are more concerned with making the scanner "Look better" than "Look correct". This is similar to how TV manufacturers turn on "Red push" and crank the sharpness control up on the default settings in order to make reds more vibrant and make the low resolution of TV look sharper.

    I looked really close to both pictures, and the linux one is blurry, the win one is sharp, and more colorful to my opinion Maybe the colors are more "real" compared to the actual photo in linux, but the blurryness is really annoying

    Epson scanners and Linux
    by fester on Thursday May 24, 2001 @ 08:58 PM
    I recently decided to enter the world of scanners, too. I chose the USB Epson 636U which looked like a good match with my Mandrake 7.2 desktop. It took me about 10 mins of installing sane and xsane, and then editing the appropriate files, but when I was done I was thoroughly impressed with the results.

    Is impossible to have differences from scanning in Windows 98 to Linux or any other OS. Sometimes is better not to find diffrences where they soese'nt exist. If you use different scanning software, look for default options, they can be really diffrent. You must understand that like a linux guru, exist also a designer guru. Ask one of them and you will be really surprised. They don't care for linux. For them better is Windows, but much better is MAC. Its very difficult for Linux as far as Adobe products doese'nt exit for Linux. I'm sure you will now tell me (has happend to me many times with linux users) that you can find for free (Adobe Photoshop is expensive) some photoshop clones for linux, but beleive me: That kind of software looks like a game to designers. With all respect for linux, i think that in this field linux has a long way to go ahead. In this moment no1. in this field is MAC, then Windows, and really far away exist Linux. (but only exist)
