Re: [NTG-context] Minimals and dvipng
Hi all, Tomorrow I will try to modify my muse-tex2png.el file so it uses the pdf output of context (or texexec), then convert to make a png file, instead of dvipng: I use this already for graphics (metapost or pgf) and it will probably be a better tool. Please Mojca no hard work on dvipng until I give more news :-) !!

Re: [NTG-context] Minimals and dvipng
But if I dvipng in the TL environment, it works like a charm. So what should I add to my minimals install, or do to have all the TL stuff not forgotten when I use minimals? dvipng is not part of the minimals at all, which means you're probably using it from TL's path, where it can't find the minimals' fonts. If you're ready to hack a bit, just copy dvipng to the minimals' path.

Re: [NTG-context] Minimals and dvipng
3. export TEXFONTMAPS=/path/to/texlive/texmf-var/fonts/map/dvips Did I write fonts/map/dvips? It should have been fonts/map/dvips/updmap (or, alternatively, fonts/map/dvips// with the trailing double slash). And it seems to work without copying the dvipng binary, and with setuptex as well. Of course your mileage may vary, but anyway, the key is setting TEXFONTMAPS.
