Psconvert to read from stdin?

Dear community,

Is there a way to make psconvert read postscript from standard input (and write image to stdout) ?


Input: Not so simple since we need to pass through the PS more than once. So this mean we would have to save it to a temp file anyway.
Output: Might be possible if only a single output, but several options yields more than one output.

Thank you for the quick explanation!
