Re: d.legend in python loop draws larger background than requestes

You mean providing the data for it?
I'm looping through 56 1x1degree DEMs, in about half of the cases the
legend gets the larger rectangle.
I used this same script before without any issues, the only difference is
that now I'm setting the range for the legend.

I tested it without the range parameter and it still gives the same
results. I'm setting up a virtual linux machine to test it, hoping it can
be something OSX-related...
