[Insight-users] Example - Image1

[Aya El Gebeely]

Hi Yiming,

In image1.cxx file the codes only illustrates how to set an image but not
further than that...

The following examples illustrates other steps..you may consider that each
example adds a step to pipeline of reading/writing an image , so in
Image5.cxx you will see  the code for writing an output image, (where you
will have output)

const bool importImageFilterWillOwnTheBuffer = true;
  importFilter->getSetImportPointer( localBuffer, numberOfPixels,
                                  importImageFilterWillOwnTheBuffer );
  // Software Guide : EndCodeSnippet


  //  Software Guide : BeginLatex
  //
  //  Finally, we can connect the output of this filter to a pipeline.
  //  For simplicity we just use a writer here, but it could be any other
filter.
  //
  //  Software Guide : EndLatex

  typedef itk::ImageFileWriter< ImageType > WriterType;
  WriterType::Pointer writer = WriterType::New();

  writer->SetFileName( argv[1] );

  // Software Guide : BeginCodeSnippet
  writer->SetInput(  importFilter->GetOutput()  );
  // Software Guide : EndCodeSnippet


  try
    {
    writer->Update();
    }
  catch( itk::ExceptionObject & exp )
    {
    std::cerr << "Exception caught !" << std::endl;
    std::cerr << exp << std::endl;
    }


You will find everything is illustrated in details, in chapter 4, sections
4.1 and 4.2 in ItkSoftwareGuide.pdf
