[pdftex] Cannot get \includegraphics to work

[Claus Tondering]

I have a LaTeX document in which I want to include a PDF picture.

If I do this:

   \usepackage[pdftex]{graphics}
   :
   :
   \includegraphics{xx.pdf}

everything works fine.


But if I do this:

   \usepackage[pdftex]{graphics}
   :
   :
   \includegraphics[1cm,2cm][10cm,10cm]{xx.pdf}

nothing gets included in the generated PDF file. I can see that
pdflatex reserves enough space for the picture, but there's no picture
in the actual output. Using \includegraphics* instead of
\includegraphics makes no difference.

What do I do wrong?
