This function will add a single group object to your current drawing. This is even true for circles, ellipses and circular arcs. The line width is recognized, but line style and other options are not. No fonts are recognized.
Any text found in the Postscript picture is rendered in roman font.
Even worse, no different text sizes are recognized. Nevertheless, this is a powerful tool. It has been tried on a considerable number of Postscript files, and in most cases generates a reasonable approximation of the picture. It will always be necessary to edit the picture after importing, but the work is much simpler than recreation of the picture from scratch would have been. In particular showcase files can be usefully imported into Ipe with this function.
