[Insight-users] 2D png to 3D gipl : ImageSeriesReader

[Luis Ibanez]

Hi Jianguo,


Please find below an example of code that will read
a set of .PNG files and save them in a single GIPL
image file.


Regards


   Luis

#include "itkNumericSeriesFileNames.h"
#include "itkImageSeriesReader.h"
#include "itkImageFileWriter.h"
#include "itkImage.h"

int main(int argc, char * argv[])
{
  typedef itk::Image<unsigned char,3> Image3DType;

  //
  // Here we generate filenames like
  // myImage000.png, myImage001.png  .... to myImage200.png
  //
  itk::NumericSeriesFileNames::Pointer fileIter =
                      itk::NumericSeriesFileNames::New();

  fileIter->SetStartIndex(   0 );
  fileIter->SetEndIndex(   200 );
  fileIter->SetIncrementIndex( 1 );
  fileIter->SetSeriesFormat("myImages%03d.png");

  itk::ImageSeriesReader<Image3DType>::Pointer reader =
               itk::ImageSeriesReader<Image3DType>::New();

  reader->SetFileNames( fileIter->GetFileNames() );
  reader->Update();


  //
  //  Here we save the image in GIPL format
  //
  itk::ImageFileWriter< Image3DType >::Pointer writer =
                   itk::ImageFileWriter< Image3DType >::New();

  writer->SetInput(   reader->GetOutput()  );
  writer->SetFileName("myImage.gipl");
  writer->Update();

  return 0;
}
