does jPod support full PDF Specification ?
sorry - this message got totally ignored as i did not monitor this form until now.
and - to answer your question: No.
There is just not enough time in this life to get this done, from sophisticated color spaces over XFA up to tagged PDF...
We support a very broad subset of the spec, very sound in the basics (syntactic layer, data structures), reasonable rendering support (not enough maybe for a publishing program), good high level semantics (PD objects).
Is there anything special you are looking for?
I was looking on different PDF libraries to see how much they can do, so I did not have anything special in mind.
To see what you can do with jPod - have a look at www.cabaret-solutions.com.
To have an impression of the currently open sourced code, have a look at the examples.
