There is some UNIX package you need for doing this kind of
conversion (probably netpbm). As for me, when inserting a png
image in a TeXmacs document, I get the following output on the
console :
[[
...
pnmtops: warning, image too large for page, rescaling to 0.990291
pnmtops: writing color PostScript...
pnmtops: warning, image too large for page, rescaling to 0.990291
pnmtops: writing color PostScript...
pnmtops: warning, image too large for page, rescaling to 0.990291
pnmtops: writing color PostScript...
pnmtops: warning, image too large for page, rescaling to 0.990291
pnmtops: writing color PostScript...
]]

This 'pnmtops' command at least is something you need.

You should not dive into the code, all the more because what you are
looking for doesn't exists ;-D ;-D.

There is no intermediary LaTeX file generated when displaying a PS,
because TeXmacs rendering engine is wholly implemented from scratch,
and completely independent from LaTeX, TeX, and the like.

The LaTeX export is implemented as an independent add-on,
in Scheme. I would suggest figuring out what is exactly the
bug, then hacking a quick fix in Perl (and then submitting
a bug report to us... :-).
