itk new Imgae

  using PixelType = float;
  enum {ImageDimension = 2};
  using ImageType = itk::GPUImage<PixelType,ImageDimension>;
  using IndexType = ImageType::IndexType;
  using SizeType = ImageType::SizeType;
  using RegionType = ImageType::RegionType;

  

  ImageType::SizeValueType sizeArray[ImageDimension] = { 128, 128 };
  SizeType size;
  size.SetSize( sizeArray );

  IndexType index;
  index.Fill( 0 );

  RegionType region;
  region.SetSize( size );
  region.SetIndex( index );

  ImageType::Pointer moving = ImageType::New();


  moving->SetLargestPossibleRegion( region );
  moving->SetBufferedRegion( region );
  moving->Allocate();

以上代碼實現了itk 從無到有創建一個圖像。
