In all of the imagemagick display installations I have, when I use the

and can find nothing in the internet about it. That suggests to me that it's - again - a use-flag issue. Is there some use flag I have to use
to have a colored line with a transparent background?
I finally figured this out. In order to draw on images with display(1)
draw and have proper backgrounds, the /*-alpha on*/ option has to be
specified.
