Thanks!

Oh that's nice, thanks for the information

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.

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.
Cheers,

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.

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,

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.
