I am using a point-size of 50 and I would need to make the image quite large so that it works in every case. That's why I preferred my code modification. Also I would like to use scrambling together with overlapping characters but I see that this currently is not possible. I am aware of the fact that I need to maintain my modifications if I make an update. That's why I documented the changes well. However, to be honest, I still hope that you find some of my modifications worth to be integrated in a future update of GD::SecurityImage so that I do not need to apply the modifications again.
