[Matplotlib-users] roipoly function

[Nick R. <ncr...@gm...>]

Hi listserve,

I was wondering if anyone had implemented an roipoly function for
matplotlib?  I am looking for a function that will display a plot, accept a
series of left clicks to select an arbitrary number points in a sequence,
draw the polygon as I click, and complete the polygon with a right click on
an appropriate point.  The function would return a mask array indicating
which points are inside the polygon and which are not.
