I recently tried Parabola, downloaded an ISO, burned it to a DVD±RW with
growisofs.
growisofs -dvd-compat -Z /dev/rcd0c=/path/to/image
I tried to take screenshots but there was an error about not finding a file
or folder or invalid path, something to that effect.
I discovered a new for me tool -- 'import' which is, so I understand, part of
the ImageMagick set.
import -window root screenshot.jpg
You can save the screenshot as several other image formats by changing the
extension to 'png' or 'xpm'.
Here's the new to me part, capturing windows.
import -window 0x14002fd mozilla.png
That's a window ID -- where did that come from?
xwininfo
will give you the ID (it prompts you to click on the desired window).
Or, you can simply type 'import screenshot.png' and click on a window or
image to capture a shot (the mouse cursor will change into a crosshair).
I can't get the decoration in, not even with the option '-border'.
