In order to display images TeXmacs relies on the Ghostscript program. This program makes it possible to display postscripts graphics in X Window applications. Other programs like tiff2ps, pnmtops, giftopnm, etc. are used to convert other image formats into postscript.

The Ghostview program is a popular postscript file viewer based on Ghostscript. It may be used in combination with TeXmacs for previewing documents before you print them.
