If you have to create PDF's then youll probably eventually end up looking at PDF::API2 which by all apearances and tests ive done is a worthy piece of code. However, the documentation is utterly excreble. Finding your way around the module and its children is painful indeed

This too is something which I found when I was last working with PDF::API2 - The result of my last tinker with this module can be found here. Whilst not a complex example, it may help you in what you are doing.
