Thanks Marc,
the extra arguments to postscript still don't produce something that
PowerPoint will accept.
With your call, PP still displayed only the icon. PP did not generate its
own png file.
Since my immediate goal is the projection screen for a PowerPoint
presentation, I will go
directly to the png file. For the proceedings and for paper I will
continue to use the pdf file.
