Thanx for that quick response! It is the right direction, but doing this for one image is not enough. when having multiple images, the distances between them must be scaled, too.
I will extend your example to scale all nodes and their positions, too. I try it tomorrow and post the result here. Nico > Felipe Heidrich <mailto:[email protected]> > 26.
