It looks as if poly_editor is broken in 0.91.2 and the trunk. Is that your observation as well?
This has been fixed in SVN (on both the trunk and the 0.91.x branch). On both versions, the line (that makes up the draggable markers) was never added to the axes, so it doesn't get a transform, and all the markers are drawn in the lower left. For the trunk, there were a couple updates to use the new transforms methods. Also, numpy arrays (which are now used for the polygon data) do not support insertion, so the call to "insert" had to be rewritten as creating a new array. See r4878 (trunk) and r4879 (0.91.x maintenance). Cheers, Mike Rob Hetland wrote: > > I do this sort of stuff all of the time.
