Hi John,
(3) Hadn't thought about repeated {{{\newcommand}}}'s. That would indeed
cause problems.
(2) It's odd the items come out in a different order. But maybe this
would shakeout in the notebook overhaul that is coming up? I think even
with the pictures at the end, the suggested changes would be an
improvement.
(1) So it seems that some of these latex packages inject {{{\special}}}'s
into DVI's and in the past you would have to run dvips to get out
something usable. Anymore, my habit is to avoid DVI altogether and
strictly run pdflatex with PDF's as output. So my suggestion was to look
at DVI's by running {{{dvipng --picky}}} to see how "complicated" a DVI
might be. If {{{dvipng --picky}}} failed, then take another approach: run
pdflatex and then use convert to make a PNG for the notebook. So the
"smarts" would be in {{{--picky}}}, as I think was done elsewhere.
Can you make a DVI of the graph example in latex_examples and render it
properly in a DVI viewer? Is it just me?
More generally, I've been thinking that the latex->DVI->PNG conversion
process could perhaps just be replaced by pdflatex->PDF->PNG. Mostly
because it seems to me like the capabilities added into TeX for graphics
(like we've been adding) have outgrown the DVI format.
The cons would be that a PDF viewer would have to be installed on a
system, as opposed to xdvi (or similar), and the imagemagick suite (for
convert) rather than dvipng.
The pros would be that view() could just call the PDF viewer every time
from both the command line and the notebook, without using the
{{{pdflatex=True}}} option, and without a second conversion step. And
%latex and %pdflatex could be consolidated into just the latter command.
Thoughts?
Rob
