I am sure it's just a simple key i need to press along with PrtScn ? There are various methods for scaling and saving in lots of file-formats , but if you can't use them (like making snapshots for documenting the menues) your ditribution should have a tool to take snapshots from your screen, that can be set to grab only the selected window. I'm using KDE on my SuSE7.3 ,so KSnapshot is what i use (and like) . The files produced by KSnapshot can be used anyway you want, like integrating it in some kind of manual, etc... hope this info helps regards, Peter -- Peter Buckenleib Am Europakanal 8 91056 Erlangen Tel: 09131 992234 Fax: 09131 791045 Mail: [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] how to correct optical distortions of wide-angle lenses?
Hi folks, is there a way to correct optical distortions of wide-angle lenses ( most annoing within architectural pics ) using gimp ? I'm dreaming of something like stetching the upper side, interpolate all the pixel-lines down to the bottom-line (which remains unstretched) and then cutting away the resulting triangles on the left and right side to restore the original size of the scan. I didn't find a hint how to do that till now. Perhaps somebody knows about some script-fu module(s) or docs i am missing or didn't find yet. Thanks in advance Peter ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Peter, That's an interesting idea. Have you thought of doing the correction as you take the photograph? If you keep the film plane parallel to the front of the building you won't have the distortion. Without a full, tilt-and-swing bellows arangement on your camera, you can do it by choosing the proper lens and shooting position. Of course, sometimes you just cannot get to the right position. :-) Good luck! Rich Dr. Richard B. Shepard, President Applied Ecosystem Services, Inc.

But i do not own a camera that is capable of that (SINAR,Rollei, etc). These would be too heavy, complicated and time-consuming to be used at holliday-trips. I'm using a Minolta 800si and a SIGMA-Zoom (28-200). As long as i had time enough to convert my bathroom into a darkroom for days, i used a method like this to correct that distortion when exposing the prints. So i thought this could be done mathematically on the pixels in RAM. There are more than needed for a close to chemical-print since i got a Canon FS4000 filmscanner. thanks for your Mail Peter -- Peter Buckenleib Am Europakanal 8 91056 Erlangen Tel: 09131 992234 Fax: 09131 791045 Mail: [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
