Hi everybody,
Increasing the memory did not help, so I created a Text2D with a relative
small point size (50) and scaled it with
Transform3D scalet3d = new Transform3D();
scalet3d.setScale(new Vector3d(100,100,100));
which is working fine.
My problem now is, I do have points which needs two labels, one
align_first (which I already achieved using the point coordinates) and one
align_last. My problem is how can I calculate the length of the given
string, so that I can adjust the x-coordinates?
Thanks Desiree
