Some replies I stole off a mailing list, where the same question came up:
first reply> latest koffice can edit pdf's, not tried saving as doc though afterwards...
original poster> Thanks, tried it. But kword makes a bit of a mess of the PDF.
third reply> there's one breathtakingly horrible solution, but it might be the only practicable
one: write a quick script which uses Ghostscript to turn the PDF into a sequence of PNGs, then outputs an RTF file with said PNGs embedded, one to a page.
third reply> RTFs (according to the v1.5 spec) can also contain "Enhanced Metafiles" or EMFs, which seems to be some kind of Microsoft vector format. I think OOo Draw can import these, but I don't know if there's any sensible way to convert PDF to EMF. EPS, it seems, is not supported :-(.
sadistic reply> Try reading "Digital Typography" by Donald Knuth.
fourth reply> If the issue is getting from LaTeX to word, then using Hevea
to generate html as a common
format is a workable, if not perfect solution, even for moderately
complex documents, although some hand editing afterwards is likely.
fifth> Check out http://www.scansoft.com/pdfconverter/
sixth> Sure: pdftotext uses the xpdf code to extract the text from a pdf
document for instance. As I said originally, it's *potentially* hard,
but most of the time, you can get the text out.
sixth>But the originally poster wanted the full formatting, which is a bit
more difficult & rtf doesn't really cut the mustard.
There are other tools for other situations, like latex2html...
