TeX output in IPython qt 0.11

[hm70]

I've seen at http://research.scios.ch/inet/doku.php?id=ipy_tex a
screenshot showing simpy code output as inline PNG in the new IPython
version (qt). Apparently the _repr_png_ method together with --
pylab=inline can be used to render any latex output on the fly.
My question: is it feasible to provide simpy objects with a suitable
_repr_png_ method?

Cool. I knew there had to be a way to render LaTeX in the qtconsole
other than just using matplotlib.

Probably the best way to use this with SymPy would be to create a
custom printer that sends the output of latex() through the TeX
command. You can play around with this. I'll take a look at it later
to see if I can get it to work.

We also have a function preview(), which I think can be modified to
work with the qtconsole (again, I need to play with it).

Hi
Thank you for the answer. Meanwhile I had a conversation with the author who fed me with hopes but discouraged me from changing any core code.

Actually, the author and I are currently discussing off list ways to
get this to work by default (perhaps it should be brought on list).

Yes, please do. I can definitely point in the right direction on the
IPython side of things. To see how the printing works and how to get
an image back to the frontend, have a look in
IPython.extensions.sympyprinting.

Cheers,

Brian

Thanks. This doesn't exactly tell me how to make the SymPy pretty
printer return a png, but I'll look into it.

I noticed that you are doing some replacements for things like
\operatorname that mathtext doesn't support. We should fix some of
this stuff upstream, so you can just do latex(mode="matplotlib") and
it will give you a suitable form.
