What is the status on support for xref/iref streams? When I try to use a PdfReader to parse a acrobat 7/8 dynamic pdf I get a message about "Cannot handle iref streams". There is an encouraging comment in the code ( TODO: We have all code to handle them -> just do it ). Is there any timeline on this? I'd be happy to help in any way I can.

Is the current codebase up on a public SCM? Looks like the sf.net CVS repository was closed out.

I'm also interested in this - bumped into trying to read one of these PDF's today. I tried playing with the source but didn't get very far. :) Can you offer any tips for editing the code so I can read this PDF?

Thanks for a great library!

Hey guys,

I know this is a free software project so I'm not trying to be too bothersome.

Can the project admin respond with "won't fix" or some tips? I just got a large batch of these PDF's - if it's not something you're able to implement I understand (have my own OSS project that takes a backseat to real life/job responsibilities) - I'd just like to know if I should wait or look at other libraries.

Thanks again, and all the respect in the world :)

Any updates on this? I am stuck due to lack of this feature.
Is there a workaround for the same?

Still not yet implemented.

A user provided a workaround:

Do you have any near term plans to implement XREF streams ?
without it complex PDF files cannot be used at all and render this otherwise wonderful library useless

thank you in advance

throw new PdfReaderException(PSSR.CannotHandleXRefStreams);
// TODO: It is very high on the todo list, but still undone

Yes, we have plans. No, I cannot announce any dates now.
