Re: [matplotlib-devel] patches have incorrect alpha values

The example (e) in my previous script have a code and a text label mismatched. I'm attaching the corrected one. I took a more look on how a patch is drawn. the draw() method of a patch calls draw_path method of the renderer, which seems to be responsible for both "fill", and "stroke". But there is

I'm definitely not smarter than you, but I had looked at backend_cairo more recently :) I've done the merge. Cheers, Mike Ryan May wrote: > Checked in on the branch. I'm seeing some merge conflicts on > backend_cairo.py at the moment, so I'll let someone smarter than me merge to > trunk. :) >

[matplotlib-devel] patches have incorrect alpha values

Hi, When drawing a patch, the alpha value of its edgeolor is ignored. The following command draw a circle whose edgecolor has alpha=1, instead of 0.1. gca().add_patch(Circle((0.5, 0.5), 0.3, ec=(1,0,0,0.1), fc="none")) Attached is a little test script and its output. It

Checked in on the branch. I'm seeing some merge conflicts on backend_cairo.py at the moment, so I'll let someone smarter than me merge to trunk. :) Good find. Ryan On Mon, Mar 23, 2009 at 1:01 PM, Sandro Tosi wrote: > Hi all, > I found a really nice typo: > > >>> > $ svn diff > Index: doc/use

Re: [matplotlib-devel] can't copy 'lib/matplotlib/mathtext.py'

Perhaps a merge failed on lib/matplotlib/mathtext.py? If you know you don't have any local changes to that file that you need, you can just remove it and "svn up" again. I can't see a reason why this is a repository-side problem... no properties have changed on that file for a long time. Mik
