PL/SQL generate PDFs

Something I have been meaning to play about for quite a while is the use of a number of free PL/SQL libaries for creating PDF documents on the fly in PL/SQL code.  Some the libraries out there are :

For completeness, there is a paid libary http://plpdf.com/ but as it costs I'm not going to play with it for the moment.

I'm going to have a bit of a play with the end result of storing the resulting PDF as a BLOB in a table for use in a document library.

Update to follow!
