Comment:
{{{%latex}}} seems to fail on the use of {{{dvipng}}}. When I run dvipng
outside of Sage on a dvi file having graphs in it, I get boatloads of
warnings:
{{{dvipng warning: PostScript environment contains DVI commands}}}
the failures seem to occur when dvipng calls Ghostscript - I see errors
from Ghostscript when I run dvipng outside of Sage, and if I use
{{{%latex_debug}}} in the notebook, the last output is a Ghostscript error
message.
Outside of Sage, I can take source with tkz-graph code, run (plain)latex,
then convert the dvi to Postscript with dvips, then convert to PNG with
imagemagick's convert. I get full pages with numbers, and the resolution
looks a bit crummy, but I presume that can be fixed with options.
(1) Is it reasonable to expect dvipng to process these dvi files right?
Should we (me) contact the tkz-graph author to inquire?
(2) Is it worth the trouble to go latex->dvi->ps->png for a
{{{%latex}}} cell, or just be content with {{{%pdflatex}}} working
properly?
This is very nice. To be able to go get a pretty PNG of a graph in the
notebook with just a few lines of code will be fantastic. I'll be working
on a review.
