[Insight-users] ScalarImageToHistogramGenerator in Python

[Bradley Lowekamp]

Hello,

What version of ITK and WrapITK are you using? What platform? What python? etc...

I am not sure how you are getting your list of methods. However I have the latest build from master and I get the following:

 dir( itk.ScalarImageToHistogramGenerator.IUC2.New() )
Out[12]:

 'BreakOnError',
 'Clone',
 'Compute',
 'CreateAnother',
 'DebugOff',
 'DebugOn',
 'GetCommand',
 'GetDebug',
 'GetGlobalWarningDisplay',
 'GetMTime',
 'GetMetaDataDictionary',
 'GetNameOfClass',
 'GetOutput',
 'GetPointer',
 'GetReferenceCount',
 'GetTimeStamp',
 'GlobalWarningDisplayOff',
 'GlobalWarningDisplayOn',
 'HasObserver',
 'InvokeEvent',
 'Modified',
 'New',
 'Print',
 'RemoveAllObservers',
 'RemoveObserver',
 'SetDebug',
 'SetGlobalWarningDisplay',
 'SetHistogramMax',
 'SetHistogramMin',
 'SetInput',
 'SetMarginalScale',
 'SetMetaDataDictionary',
 'SetNumberOfBins',
