[Matplotlib-users] Alpha channel issue with fill() + Cairo backend

2007-10-26 Thread Ken Conley
When I switch to the GTKCairo backend, the alpha value no longer seems to get passed when I use fill(). I looked at backend_cairo.py and I believe this is because _fill_and_stroke always uses ctx.set_source_rgb, instead of ctx.set_source_rgba. I hacked backend_cairo.py to look at gc._alpha (I had

I tried to change the value and the highest one I can use is 2 so it's not a big improvement for what I understand. You can contact me if you need other test naturally N. Le Friday 26 October 2007 12:24:34 Michael Droettboom, vous avez écrit : > It's great to have narrowed this down! Unfortuna

Thanks for this information. It looks like the font outline data is somehow getting corrupted before freetype renders it. Again, however, I can't reproduce it on my machine (I've attached a copy of what it looks like for me), so I'm still pretty stumped. My suspicion is that it's a 64-bit vs
