[Insight-users] Problem with reading binary image

[xiu jiang]

Hi, all
 
I'm trying to read TIFF image which contains the pixel value of only 1 and 0 and use it as a binary image. But I found the pixel  value is changed from 1 and 0 to 198 and 160 after I read it. Is there anybody who can tell me how to fix this problem? below is the code.
 
typedef itk::ImageFileReader< ImageType > ReaderType;
ReaderType::Pointer reader = ReaderType::New();
std::string filename = inputDirectoryName;
reader->SetFileName( filename );
reader->Update();
return reader->GetOutput();;
 
Thanks,
Xiu
