I suspect this can be easily implemented.

Synopse pdf is the reason I started fppdf. Synopse is heavily Windows
centric, but otherwise quite capable.
Fppdf is a young library (although it required many months of work)
I am sure many improvements will be made as the reporting library develops.
A canvas descendant that renders to pdf is planned, but not very high
Patches and suggestions are definitely welcome. The library is intended for
production, so quality is important.
