bit of googling brought me to this very nice post

Hello.
Is there an easy way to load a picture into an array so as to apply a
matrix transformation to all the xy-corrdinates ? If a solution without

Hi there!
I'm using view to display my graphs and posets. I would like to have it
run the viewer (xdg-open, which in the case at hand is evince) in the
background. This is on a linux box, running sage 6.5.beta2.
Many many thanks!
Martin
