automating screenshots / commandline screenshots

[Axel Etzold]

Dear all,

I need to take a very large number of screenshots and save them in individual image files.
I have read about ksnapshot, and I would like to somehow combine it with
a scripting language, such as Ruby.
Unfortunately, I couldn't figure out how to:

- send the "print screen key" to X (or KDE or the Kernel or ...), from a script 
- drive ksnapshot from the command line, so as to parse the choices
that appear in the popup menu as command line options (take a new screenshot, take the whole screen, save the image as ..) .


This all works, if I do it by hand, using Alt-key combinations, but not 
in a script.

Is there a way to achieve this with ksnapshot or is there another
application, that can be used from the command line, specifying the
options there ?

Thank you very much !

Best regards,

Axel
