Hello everybody,
I'm in the process of replacing R by matplotlib to plot all of our charts.
I'm hacking the PDF backend because I need this format to import
charts in ConTeXt (this is TeX macro package, similar to LaTeX, we use
to produce PDF reports).
My first question, very basic, is why funct

I am all for a good PDF backend, but you should be aware that under

That would be great for pdf generation under windows, where you can
hardly assume the user has xpdf or epstopdf installed. It h

In module ft2font, the method FT2Font.get_charmap returns a dict that
maps glyph indices to char codes.
I don't understand the purpose of this mapping, and why the method
doesn't return the reverse mapping, i.e. char codes mapped to glyph
indices.
For example, in backend_ps.py, line 754, the char

The TODO list is in the comments of backend_pdf.py:

One problem was that it was large compared to mpl at the time, and mpl
was pure python. So it c
