Ok, Jan-Åke, some questions.
First, the preamble. I invoked dvipng so:
dvipng -bg 'rgb 0.980 0.941 0.902' -depth <dvifile>
to give:

1. Here I had colour specials in the latex file. In future I will not
need them, right? Instead I'll pass them direct to dvipng, as above.
2. I should prefer your -depth and -height flags, extracting the
metrics info from the output above, rather than extracting it from
the latex log file? Reason: the log file info is going to be wrong if
I invoke dvipng with the '-T tight' option, right? (and I would like
to do so so that I can strip off the front margin of a displaystyle
equation).
Have a good weekend,
Angus
