[vtkusers] Re: [Insight-users] turn on/off a filter in pipeline

[Renaud Isabelle]

Thanks. 
 
But don't you think I will have to define 2 types of rescalefilter such as:
 
typedef itk::RescaleIntensityImageFilter<ImageType3D,  ImageType3D> RescaleWithLog;
typedef itk::RescaleIntensityImageFilter<ImageAdaptorType, ImageType3D> RescaleWithoutLog; 
 
Because, if on,  the input of my rescale filter is a filter's output. If off, the input of my rescale filter will be an ImageAdaptor. OR can I switch so easily the input of my rescale filter?

Karthik Krishnan <Karthik.Krishnan at kitware.com> a écrit :
if (on)
{
logFilter->SetInput( adaptor );
rescaleFilter->SetInput( logFilter->GetOutput()) ;
}
else
{
rescaleFilter->SetInput( adaptor );
}

rescaleFilter->Update();
