<div>HI,<br>
</div>
I use double scaler type from input but work with (Black or white ) threshold setting My code is follow bellow
<br>
int apply = 0;<br>
imageThreshold->SetInputConnection(firstColorMapper->GetOutputPort());<br>
imageThreshold->ReplaceInOn();<br>
imageThreshold->SetInValue(255);<br>
imageThreshold->ReplaceOutOn();<br>
imageThreshold->SetOutValue(255);<br>
imageThreshold->SetOutputScalarType(fixedConnector->GetOutput()->GetScalarType()); //double<br>
imageThreshold->ThresholdBetween(VTK_SHORT_MIN, VTK_SHORT_MAX); <br>
imageThreshold->ThresholdBetween( -3495, 2161 );<br>
imageThreshold->SetOutValue(apply ? 0 : 255);<br>
imageThreshold->Update();<br>
<br>
<br>
<br>
double low = (!enableThreshold) ? range[0] : lowThreshold;<br>
double upper = (!enableThreshold) ? range[1] : upperThreshold;<br>
<br>
<br>
vtkSmartPointer<vtkImageThreshold> imageThreshold2 = <br>
vtkSmartPointer<vtkImageThreshold>::New();<br>
// imageThreshold2->SetInputData(mImage);<br>
imageThreshold2->SetInputConnection(secondColorMapper->GetOutputPort());<br>
imageThreshold2->ReplaceInOn();<br>
imageThreshold2->SetInValue(255);<br>
imageThreshold2->ReplaceOutOn();<br>
imageThreshold2->SetOutValue(255);<br>
imageThreshold2->SetOutputScalarType(fixedConnector->GetOutput()->GetScalarType()); //double
<br>
imageThreshold2->ThresholdBetween(VTK_SHORT_MIN, VTK_SHORT_MAX); <br>
imageThreshold2->ThresholdBetween( 160, 6088 );<br>
imageThreshold2->SetOutValue(apply ? 0 : 255); <br>
imageThreshold2->Update();<br>
<br>
