-------------------------------------

We've actually overhauled this API in 2.0 for that reason, you should take a look and see if it fits your needs.

> We are trying to implement custom logic for overlaying documents. However, current PDFBox implementation is excessively strictly encapsulated and it's not really possible. What makes things worse, overlay implementation is very strict about the way output gets processed. Please find attached link to the patch that makes overlay logic more flexible by:
> 1) Making some of the methods protected;
> 2) Moving output logic to a method that can be overridden.
> 3) Moving getting list of pages to be processed logic to a method that can be overridden.

> If there are some adjustments that should be done or a separate version made for trunk - please let me know, I'll get to it immediately.
