Drawing polygons in numpy arrays

Question

I\'m trying to draw polygons like this:

In [1]: canvas = numpy.zeros((12, 12), dtype=int)

In [2]: mahotas.polygon.fill_polygon(
   ...: [(1, 1), (1, 10), (1         


        

Answer 1

I think the reversal is required because numpy references array coordinates as y,x (row, column) where most other programs issue coordinates as x,y.
