Since I cannot print screen (or screen capture) the output of xscreensaver (there are some very nice graphics!), how can I redirect the output of xscreensaver to a PNG file, using the command-line?
I want to "grab" some images as wallpapers. I want to use command-line because this way I can select programatically which xscreensaver display mode I want.
Also I need the output to be as wide as my screen (1920x1080).
Is this possible? If so, how do I accomplish?
I tried redirecting the output but I failed miserably.
