After reading your e-mails, I must recommend ImageMagick:
 http://www.imagemagick.org/
It is free and available for most platforms (as it seemed when I was
looking at the webpage).

If you are on a UNIX system you should definitely consider installing
ImageMagick in order to get hold of the command "convert", which
makes it very easy to convert images from and to almost any format
you can think of. The following would for example turn a hpgl-file
into a tiff file:
 computer> convert survex_plot.hpgl tiff:survex_plot.tiff

"convert" used to be part of Gnome, so maybe it is already installed
for your system. Otherwise all binaries are on the website.

Maybe the convert source code can be used to implement functionality
in Survex for the feature that Graham request? It is open source...
