Hi all,
I was grepping the source code today for any remaining uses of matplotlib.mathtext in matplotlib and stumbled upon menu.py -- a menu demo/example.
Although it does use/import mathtex it seems to only use it for rendering plain (non-math) text using the to_mask function. This is something that mathtex has no equivalent of (and appears to be the only use of it).
Can anyone recommend an alternative way of writing menu.py so that it does not depend on mathtex?
Regards, Freddie.
It would be great to restore to_mask to mathtex as it can be useful for GUI frameworks that require both an RGB and A buffer (rather than a single RGBA buffer). Its implementation should be pretty straightforward, since you already have image buffer output in mathtex.
There may be a way to re-write menu.py to not depend on mathtex -- such as using ft2font directly. But since mathtex will become a hard requirement for matplotlib anyway, it may be easiest to just add to_mask and update the example to use the new mathtex APIs.
Cheers,
Mike

The menu code was a work in progress that I never finished, so
maintaining it is not a priority. But supporting the to_mask in
mathtext would be nice.
