[chimera-dev] volume viewer/mouse

[Tom Goddard]

Hi Matt,

  Eric is right.  Here it is with example Python code

from VolumeViewer import active_volume
v = active_volume()
s = v.matrix_value_statistics()
print s.minimum, s.maximum

The active_volume() call can return None, for example if no data set is open.  The matrix_value_statistics() call returns the values at the currently displayed subsampling (ie. step size).

  Your comment about the "use mouse scroll wheel" setting not working is a bug that I will look at soon.
