OK, some progress. I tried exporting my document to a PDF, and it worked - the converter I registered (foo to PDF) does kick in at that point (despite no in-LyX display). I then tried adding a dummy foo-to-PNG converter (I have a simple out.png file sitting around): cp .../out.png $$o That worked - I now have in-LyX display. This leads to some more questions. I thought LyX would be able to convert the .pdf to a format it can display. At least, that's what I understand to be happening with "Graphviz Dot," which has just this converter to "PDF (ps2pdf)": dot -Tpdf $$i -o $$o When I insert .dot files as Graphics they display in LyX just fine. So why does that work for .dot but not .foo? I verified that both .foo and .dot formats have "Vector graphics format" checked. Thanks. -- Yang Zhang http://yz.mit.edu/
