Hi folks,
I've a little problem with annotations. I'd like to use the same
annotation on more than one page. I do this by first creating the
annotation on one page and then I use
\pdfpageattr{/Annots [\the\source\space 0 R]}
on each subsequent page (were "source" is the pdf object number for the
original annotation). (Well, I actualy do a little bit more to force
pdftex to expand \the\source\space but thats by the side).
If I have other annotations on the page (say from a \href) then pdftex
generates two separate /Annots in the pdf page object, for example
6 0 obj <<
/Type /Page
/Contents 25 0 R
/Resource 24 0 R
/MediaBox [0 0 612 792]
/Annots [22 0 R] <--- generated by \pdfpageattr above
/Parent 31 0 R
/Annots [17 0 R] <--- generated by \href
>> endobj
Is this valid pdf code? Acrobat Reader 5.0.5 under Linux ignores both
/Annots while Reader 4.0 on Windows reads only the first /Annots.
Is there a way to fix this problem? Am I using \pdfpageattr correctly?
Thanks for any advice,
Cheers,
