本文档介绍了如何通过ITK库创建一个itk::Image对象，并利用ITK和VTK的互操作性，将其转换为VTK图像格式，最终使用vtkPNGWriter将其保存为PNG文件。

创建一个itk::Image,并写入到png文件


#include "itkImage.h"
#include <vtkSmartPointer.h>
#include <vtkPNGWriter.h>
#include <itkImageToVTKImageFilter.h> 
#include <iostream>

void CreateImage(itk::Image<unsigned char, 2>* const image)
{
	// Create an image with 2 connected components
	itk::Image<unsigned char, 2>::IndexType start = { {0,0} };
	start[0] = 0;
	start[1] = 0;

	itk::Image<unsigned char, 2>::SizeType size;
	unsigned int NumRows = 200;
	unsigned int NumCols = 300;
	size[0] = NumRows;
	size[1] = NumCols;

	typename itk::Image<unsigned char, 2>::RegionType region(start, size);

	image->SetRegions(region);
	image->Allocate();

	// Make a square
	for (itk::Image<unsigned char, 2>::Ind
