I spent some time looking for a direct answer to your
question with no results. However, maybe a slightly
different question might yield some result?
You are
apparently happy with the functionality of SVG::GD.
What is behind this: "I am not able to use this function in the SVG::GD module"?
Maybe there is some issue like module installation, etc. that can be
addressed? Also, let's say somebody comes up with another program
that does the same thing...what's to say that you can or can't use
that one either? What is the limiting factor that is driving the
original question?
