[Insight-users] Weird behavior fo itk::Image<>::RegionType

[Gabriel Santiago]

Sorry, but where you read

*typedef itk::Image<InputAnalyzeImage, 3> Image3D;
*
*typedef itk::Image<OutputJPGImage, 2> Image2D;*

Please, read

*typedef itk::Image<InputImage, 3> Image3D;
*
*typedef itk::Image<OutputImage, 2> Image2D;*

and

*typedef itk::ImageFileReader<**Analyze3DImage> Reader3D;
typedef itk::ImageFileWriter<**JPG2DImage> Writer2D;

*
read*
*

*typedef itk::ImageFileReader<**Image3D> Reader3D;
typedef itk::ImageFileWriter<Image2D**> Writer2D;*

Thanks,
