Re: [Matplotlib-users] mimic alpha (channel) v0.1

Ben,

Yes, you're right, but I doubt any solution that involves mimicking an
alpha channel will work for one case that I've been using.  That is,
making the legend box partially transparent.  I use that to allow the
box to fit in the plot without blocking the data and without the need to
make the upper y limit too large.

I don't notice any problems with blockiness in the text or lines in the
raster image.  I'll find out soon if the editors of the Astrophysical
Journal are okay with the figures.
