[pstricks] Superellipse

[Johan Ekh]

Hi all (again...),
one more question.

I try to plot a part of a superellipse. When I use the code below it works,

\parametricplot[linecolor=red]{0}{3.141592}{4*(cos(t))^(1.0)|3*(sin(t))^(1.0)}

but when I change the exponent to something else the 1, e.g.

\parametricplot[linecolor=red]{0}{3.141592}{4*(cos(t))^(0.5)|3*(sin(t))^(0.5)}

it does not work. LaTeX runs without error but when I create a pdf with
dvipdf
it halts at the figure. Same result if I use \psLame in pst-func.

If I look at the dvi-file, it does not contain the figure but it does not
halt at the figure.
Everything before and after the figure is produced.

Has anyone a solution to this?

Best regards,
Johan
