Re: [matplotlib-devel] pcolormesh in transforms branch

[Michael D. <md...@st...>]

It seems to have broken when I upgraded the branch to Agg 2.4.  Agg 2.4 
now handles interpolating the edges of the image with a background color 
more-or-less "correctly", and no longer needs the hack that adds 
boundary pixels to the image before sending it to Agg for interpolation. 
  Should also be much faster with large images.  Fixed in r4568.

Cheers,
Mike
