Step 10. Writing myProject.cxx

• #include "itkImage.h"

• #include "itkImageFileReader.h"

• #include "itkGradientMagnitudeImageFilter.h"

• int main( int argc, char **argv ) {

• typedef itk::Image<unsigned short,2> ImageType;

• typedef itk::ImageFileReader<ImageType> ReaderType;

• typedef itk::GradientMagnitudeImageFilter<

• ImageType,ImageType> FilterType;

• ReaderType::Pointer reader = ReaderType::New();

• FilterType::Pointer filter = FilterType::New();

• reader->SetFileName( argv[1] );

• filter->SetInput( reader->GetOutput() );

• filter->Update();

• return 0;

• }
