matplotlib-users Mailing List for matplotlib

Dear list,
I would like to create a custom image clipping mask using patches. My
constraint is that my patch is required to have an outer and multiple inner
outlines.
To provide an analogy, think of a mask used for disguise where you leave
three holes, two for the eyes, one for the mouth.
I have the xy coordinates for the 'head', and the xy coordinates for each
of the holes that I don't want to be hidden by the ensuing clipping mask.
What's the matplotlib way to construct my desired path + patch from that?
Note, it's important in my case to use a patch object. What I need to do
would not work by simply masking my image using a masked array.
Any pointer would be highly appreciated --
Denis

Hi,
there seems to be a problem with arrowprops: when you change the linestyle
to something other than 'solid', the arrowhead changes aswell and looks odd.
The problem seems to be fixed in Sage (according to that ticket, see below),
but not in maptlotlib.
