[Insight-users] How to make the input of a filter to its output

[Raghu Venkatram]

Hi Pan,

  typedef itk::FlipImageFilter <ImageType >  fFilterType;
  fFilterType::Pointer filter1 = fFilterType::New();
  typedef fFilterType::FlipAxesArrayType FlipAxesArrayType;
  FlipAxesArrayType flipArray1;

  flipArray1[0] = 0;
  flipArray1[1] = 1;
  flipArray1[2] = 1;
  filter1->SetFlipAxes(flipArray1);
  filter1->SetInput(inputImage);
  filter1->Update();
  ImageType::Pointer fixedImage = Reader1->GetOutput();

you change the flip array values to flip around the desired axis.
