| 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. Well Arthur, thanks! But just copying or linking dvipng is not enough (same result); what kind of hack would you suggest? -- Jean

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. Arthur

Thanks a lot, it works. Will there be any side-effect on normal uses of context?

Definitely. TEXFONTMAPS is the path to the various font mapping files for dvips, (x)dvipdfm(x) and pdfTeX. I would strongly advise against setting that variable for normal use of the minimals. What you could do without tweaking with TEXFONTMAPS, is to put ps2pk.map in some directory inside fonts/map in the minimals, together with the dvipng binary. Best in texmf-local, for this is the location for local changes. But then, you of course need to make sure that the necessary fonts are available in the minimals, etc. Since you have TeX Live installed, your best bet is probably to use the minimals with the special TEXFONTMAPS setting only for ConTeXt + dvipng, and otherwise use the minimals only, or TeX Live only.

Well that doesn't look too good... I wish I could use dvipng whenever I need to.

You should also be able to use TEXFONTMAPS=/location/ dvipng so that the variable is set only for the dvipng run. Maybe setting this as an alias for dvipng will also work (I don't know how unix shell aliases interact with variables) Aditya

| So you are plannig to release/improve the emacs module and document it for Maps? Well, I had not used the math mode in muse for a while and then having installed the last texlive + context minimals I found out the problem with dvipng; no improvement, I'm afraid! Documentation on the contextgarden wiki is already there. Now what is Maps again?

| Hello Jean,

| You need exactly (or at least) two things to make dvipng work: | - dvipng binary | - fonts/map/dvips/updmap/ps2pk.map

| I can add that to minimals, just a few questions below ... | It's just that one day it might be splitted (together with dvips & | different font tools that almost nobody uses) into some additional | package that one needs to install separately (with additional | arguments).

| We don't have updmap, so ps2pk needs to be either: | a) prepared semi-manually with fonts that minimals ship | b) taken from TeX Live with both fonts that minimals have and those | that are not shipped at all Hello Mojka, Thank you for taking from your time to look at that! | How many exotic fonts do you usually need? Well nothing really exotic: i just want to use context to ultimately create png images of math formulas to be shown as images on websites... | Does ps2pk require some special syntax? (reading | http://ftp.univie.ac.at/packages/tex/dviware/dvipng/fontmap.c and still | asking stupid questions ...)

No idea, I'm afraid (and no more ideas about the rest :-( )!

| There's only one thing I wonder about: [x]dvipdfmx uses the map file | that are specified in dvi (xdv) specials. | - How does dvips know which map files to use? / Is there some | "quasi-standard" way to secify map files in dvi? | - Would it make sense (in long term) to ask the author of dvipng to | honour the map files specified in dvi file instead of requiring ps2pk | to be unconditionally present? | - not to be taken seriously: (Wouldn't it be nice if pdftex/luatex was | able to generate PNGs out of the box? :) :) :)

| (Well, I know, ConTeXt is a bit different from LaTeX with respect to | map files ...) Thanks, -- Jean
