[racket] Drawing PostScript file on slideshow

Hi, I'm using Racket 5.2.1 on Gentoo Linux.
Is there any way to draw PostScript or EPS (or some other vector
image) file as pict data in slideshow?

I know that it is possible to draw PNG file by using (bitmap ..) function.
However, if i convert EPS to PNG and print it as PostScript, i see a
jaggy when zoomed-in since it is not a vector image anymore.
I want to avoid the problem.

Thanks.
