PixmapError

[Darren Schreiber]

I get the following results when I am running my update on the Schelling
model.  I've added in a method to capture the raster and create png files.
The method I added was identical to the one I was using fine with my voting
model... so I am perplexed why it is failing now.  The method is attached
below.  Note I am still using Swarm-1.3.1 on my machine at work.

Thanks in advance....
