It does. Would you entertain a "feature request" that you add an option to
strip off the LHS whitespace for me?
For now, this works well enough and is pretty fast:
pngtopnm trial004.png | pnmcrop - > trial004.ppm
(It has the additional advantage that xforms won't currently load png
natively, so we must do the conversion anyway ;-)

Ahhh. That's what they do. (I saw them in the preview documentation but
didn't recognise them.
One more dumn question. Background and foreground colours. The gs docs say
that these must be set as X11 resources. Is there a way of setting them
temporarily. A sort of:
(Ghostscript*background #rrggbb, Ghostscript*forground=#rrggbb; gs ...)
If I can find a way of going from the LyX screen font size info to a gs "-r"
option then I think that that's everything to do with the preview generation
finished.
