Hi Zhao,

Please read chapter 6 of the SoftwareGuide
http://www.itk.org/ItkSoftwareGuide.pdf

----------

You don't need to do any extra conversion
for getting an image from a file.


Just do something like


typedef itk::Image<char,3> ImageType;
typedef itk::ImageFileReader<ImageType> ReaderType;

ReaderType::Pointer reader = ReaderType::New();
reader->SetFileName( "image.mha");
reader->Update(); // <-- this reads the image

ImageType::Pointer imagePtr = reader->GetOutput();


At this point, the smart pointer "imagePtr"
gives you acces to the image that was read
from the file.
