Hi,
I try to apply a transferfunction. I want to map my gray value image to colors.
I tried:
vtkLookupTable *vtkLUT = vtkLookupTable::New();
vtkLUT->SetTableRange(image->GetScalarValueMin(),
image->GetScalarValueMax());
vtkLUT->SetHueRange(0.5,0.0);
vtkLUT->SetNumberOfColors(64);
vtkLUT->Build();
mitk::LookupTable::Pointer mitkLUT = mitk::LookupTable::New();
mitkLUT->SetVtkLookupTable(vtkLUT);
mitkLUT->ChangeOpacityForAll(0.5);
mitkLUT->Update();
mitk::LookupTableProperty::Pointer mitkLUTProperty =
mitk::LookupTableProperty::New(mitkLUT);
activationNode->SetProperty("LookupTable", mitkLUTProperty);
activationNode->SetData(image);
activationNode->Update();
But all I see is still the gray value image. Can anyone tell me what's wrong?
Regards,
Claudia
