I wanted to scan a picture and try to use it for background in X. Strangely, the preview image shows pretty much the whole thing, but when I open the picture with gimp I can only see part of the image Which SANE frontend do you use? XSane? It will scan the area you have selected in the preview window or with the geometry sliders. If you use xsane in viewer mode, it will show you exactly what you have scanned. . I suspect that I have the whole thing, but I am not sure. Anyway, I can't see it all after doing the scan, only a small piece of the original. This could be either a problem with gimp setup Use the sliders and gimp's zoom feature to check. But usually gimp shows the complete image by default. or with the scanner setup, since the last time I tried to use the scanner I wanted to zoom in on a small piece of the image, for testing purposes. So maybe it needs to be reset? If so, how? Look at the top of the preview window. There are several ways to select the zoom and selection. Bye, Henning

I have just upgraded my home machine from Slackware-8.0 to Slackware-9.0, which contained as a package sane-1.0.11. I installed it and have found that my Canoscan N670U now seems to work with the software out of the box. Congratulations, all who have been involved in this project! Question 1: Sorry, just what do I do to make the scanner accessible to users, not just to root? I should know, but I forget. Do I chmod the device? Or do I setuid root the executable? Or is there still another way which works better? Question 2: This may be off topic, but perhaps someone can point me in the right direction.

So maybe it needs to be reset? If so, how? Historical footnote: The picture is a print from a painting of the Seeadler, by a certain Prof. Chr. Rave. The print is autographed by Felix Count Luckner (i.e. Graf Felix von Luckner) and presumably dates to the lecture tour of the US which he made sometime in the 1920s. I found the picture abandoned in a house some friends of mine had just moved into, in Ann Arbor, Michigan, about 1962. Theodore Kilgore
