I'm about to implement a TeX interpreter for the graphical backend
to GNU Octave (http://www.octave.org ). The
rendering is in OpenGL context.
As I understand it, matplotlib doesn't use OpenGL at all?
Not at present -- though various people are working on it.
Could you tell me about the design and work flow for the Tex/Latex
interpreter and rendering system for TeX/Latex fonts?
There are two.� One is a Python reimplementation of part of the TeX
math algorithms called “mathtext” (I am the original author).� It
uses Truetype versions of either the Computer Modern fonts or the
STIX fonts.� It is able to produce either raster images or data that
is then used by the matplotlib backends to generate PS, PDF, SVG
The other approach is used when "text.usetex" is True.� It calls out
to a real “tex” interpreter and then interprets the DVI it produces
to convert it into a form the matplotlib backends can use.� Since I
didn’t write this code, I’m not as familiar with the details.
In the case of OpenGL, since you only want images anyway, you may be
best off using a tool like dvipng along with the preview LaTeX
package, if having “real” LaTeX as a dependency is acceptable.
