[opensuse] script for making screenshots
Hello: I would like to make screenshots of a window at every 3 minutes. Not the full display, only one specific application window. I have KDE3 desktop. How could I write a script to do it? I use ksnapshot manually for taking screenshots of windows. Is it possible to control it from a script?

I don't know about KDE3, but its successor in KF5 show in command line spectacle --help bunch of options how to take screenshot. So I'd try to call something like 'ksnapshot --help' from the command line and see... The rest could be just simple for loop or so. -- Vojtěch Zeisek https://trapa.cz/ Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux https://www.opensuse.org/

I haven't used KDE3 for ages. :-) My point is that I *suppose* You can use that KDE3 screenshot tool from command line in the same way, just try to run it from command line with the --help parameter. -- Vojtěch Zeisek https://trapa.cz/ Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux https://www.opensuse.org/

Among which seems to be one that allows it to be controlled over DBUS. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You can use import from ImageMagick in a script. I don't remember if I ever figured out how to determine the window ID needed, but I'm sure there's an answer to that on the web somewhere if you can't decipher the man page better than me. -- Evolution as taught in public schools is religion, not science.

I thought ImageMagick could do it, but looking at the man I could not find which of the tools. - -- Cheers Carlos E. R.

*DOH*! Yes, of course, and also $(NF)!... The latter seemed to work though, the former was from dabbling around about the title string and not reverting to the window-id before C&P... -dnh -- Geht nicht!?

It seems "import" can do it nicely what I want to do. I have to play a little bit with it to find the window ID automatically and move the window to the top layer. If it's covered by some other window, the covered part becomes black area in the screenshot. Thanks Felix!
