Yes. HyperDoc and 'viewAlone' use .xpm files. 'FRICASsys' transfers
data which are written to .data files. Graphics program connected
tp FriCAS can render images from .data files. In principle
HyperDoc could be changed to also use .data files, but currently
uses .xpm.

That should not be hard to add. OTOH in printed form or in .pdf
file images normally have captions, so embedded title is not
needed.

There is Postscript convention about including information about
bounding box. In fact, it would be good to be able to get
proper .eps for easier embedding.
