Hello,

I use the \pdfinfo primitive to manage meta datas in pdf files when I use pdflatex.

However, I'd like to manage :

-printing option : authorized or not

-pages extracting : authorized or not

-protection...

How can I do this ?

I heard that it was possible to do this with old versions of pdftex but these kinds of features were removed from it because it didn't work very well.

I would like to know if these features will appear again and, why not, in LuaTeX ?

optimizations are best done after the document is created and not on the fly (ghostscript can do it) the code was removed because it was too much interwoven an unmaintainable; also, such features have to be under complete user control if only because other features (\pdfobj etc) might demand such control; when the luatex backend code is redone (2009/2010)we might provide hooks for users (macro packages) to implement such features Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
