[pdftex] Adding objects to the page

[Patrick Gundlach]

Hi,

I have created an object in pdftex via 

\immediate\pdfobj stream { ... }

wich gets inserted in the pdf as (for example) object no. 1.

How do I get this object to be output on the current page? I would like
this object to be the first object on the page. I guess I need to insert
it into the /Page dictionary, right? But how would I do this?


This is for something like a watermark.
