Hi,

I have some problems adding an overlay-text to an existing pdf-file.

My first approach was to get the OverContent from the stamper, using it to
create a Graphics2D to write a string to it. For writing the string I used a
transparent black as Color.

The output-pdf looks and prints just fine. Converting the pdf to ps is
problematic though.
Converting using xpdf's pdftops results in a 100% opaque overlay-text.
Converting using gs's pdf2ps results in a ps which prints ok, but the
filesize is not acceptable. (like 5-6 mb for one page)

So my second approach was to use the UnderContent instead of the OverContent
and use a 'normal' gray (no transparency) to write the string.
Both, pdf2ps and pdftops create ps-files with a small size and both print
correctly...

... however, now comes the problem I just could not solve:
some of the PDFs already have a backgroundimage with solid white, writing in
solid gray to the UnderContent doesn't help much ...
Is there any way to write text just over the backgroundimage but under the
rest of the pdf-content ?

Thanks for any answers,
Sebastian Koch
