ITK/Examples/VectorImages/VectorImage

This example demonstrates how to create a vector valued image (an image with vector valued pixels). This is very similar to

typedef itk::Image<itk::CovariantVector<float,2> > ImageType;

VectorImage.cxx

<source lang="cpp">

1. include "itkVectorImage.h"

int main(int, char *[]) {

 typedef itk::VectorImage<float, 2>  ImageType;

 ImageType::RegionType region;
 ImageType::IndexType start;
 start[0] = 0;
 start[1] = 0;

 ImageType::SizeType size;
 size[0] = 2;
 size[1] = 3;

 region.SetSize(	size);
 region.SetIndex(start);

 ImageType::Pointer image = ImageType::New();
 image->SetRegions(region);
 image->SetVectorLength(2);
 image->Allocate();

 ImageType::IndexType pixelIndex;
 pixelIndex[0] = 1;
 pixelIndex[1] = 1;

 ImageType::PixelType pixelValue = image->GetPixel(pixelIndex);

 std::cout << "pixel (1,1) = " << pixelValue << std::endl;

 return EXIT_SUCCESS;
