Undefined methods in Display.py

[Richie]

Hi there, me again, Ubuntu 10.4 x86_64, Python 2.6.5 and ImageP 2.9.2.

In order to get OverPlot() to work I had to add some extra imports to Display.py:

from numpy import arange
from numpy import cos
from numpy import sin

after this it worked.

Thanks for reporting, the fix suggested is correct: in Display.py change the line:
from numpy import zeros
to
from numpy import zeros, sin, cos, arange

I have added this to the next upload.
