Hi,
I have encountered a problem with this simplified code where I produce
a windrose with some alpha level.
Then read this png image to check.
Then discover that the colors are not correct.
What is the mistake ?
I am puzzled.
I use matplotlib 1.4.3
The correct windrose with alpha colors

The read png image.

I can't find it right now, but there is an issue on the scikit image issue
tracker which was a similar problem. I suspect the problem is that our png
read is not sophisticated enough and your png maybe encoded ckmy.
