[matplotlib-devel] examples/widgets/menu.py and mathtex
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?

Re: [matplotlib-devel] examples/widgets/menu.py and mathtex
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.

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.

[matplotlib-devel] please add this example: legend translucent
Hi all, I really liked the snipped John wrote in a mail some time ago, so I mock up a very simple example to set the alpha on a legend. It seems interesting to have such an example, also in the gallery. Since I don't have much time to dive into the sphinx example generation and so, I just hand you the code, asking to include it.

Done in 7279. And just FYI, if you're just adding an example to a directory that is already included in the examples gallery (I put this one in pylab_examples), there's nothing to be changed. It will be automatically included.
