I'd like to include a graphic as watermark in a document with the
twoside option and asymmetric page margins adjusted with the
geometry package. There's a plethora of packages that are suitable for the task, but with a few restrictions:
xwatermark package is simple to use, but I can't specify options for even and odd pages at the same time, so either the watermark appears only on half of the pages or it's page-centered rather than text-centered.
With packages such as
watermark, I can't exclude the watermark on specific pages, e.g. the title page and certain pages with diagrams.
Lastly, packages like
atbegshi provide access to
dvi internals, but I don't have the time to work it all out myself.
So my question is: what is the most elegant way to implement such a flexible watermark? If it is relevant, I'm currently using
PSTricks on Windows 7, but may well switch to
PGF/TikZ on Linux in the future...
Thanks in advance.
