For sure... and it could be broken tools of course - but if the PDF spec
says that image metadata must be preserved then I'm surprised the tools
don't do it. I'm getting the impression at the moment that the spec is
likely to say that images are recoded when inserted into a PDF file, and
no mention is made of what to do with metadata.

Let me know if you do - be interesting to hear what you find out.

If the PDF spec's on Adobe's web site then I haven't been able to find
it yet...
