It helps a lot, thanks, but ...

... I need to generate bar codes following the ean standard (wich is in 
widespread use in the book industry and is based on ISBN plus other data).

I currently use a modified version of the bookland.py 
(http://www.cgpp.com/bookland) script to generate my bar codes, 
but maybe I can write a new extension class with the interface excpected 
by the barcode reportlab extension.

Is there any docs from where I can get started (apart reading the code 
...:-))?

Assuming this is feasable, I'will then just have to use standard 
pdfgen/platipus calls to embed the bar codes in the generated pdfs?

Any problem with pdfs 20-30 pages long on a two columns layout with 
about 30 barcodes/page?

Thanks again,
__peppo

PS: if someone is curious, I am trying to automate a procedure now done 
largely by hand using QuarkXpress.
