[ITK Community] [Insight-developers] PROPOSAL FOR IMAGEIO: class to get image attributes before reading image

[Simon Alexander]

I do this sort of thing using itk::ImageIOFactory::CreateImageIO

after using the method ReadImageInformation(), you have access to the
underlying


GetComponentType(), GetPixelType(), etc.

hope that helps
