[Insight-users] how to convert the pixeltype of a image

[shiwei]

Tanks for your answer!However when I did what you have told, it still have some problem below:


itk::ExceptionObject<0031e508>

Description:itk::Error:TIFFimageIO:TIFF supports unsigned/signed char,unsigned short/signed short only.


As I said before, I want to use some tiff images ,however  TIFF support unsigned/signed char,unsigned short/signed short only, so I'm still asking if there is a way to convert the uchar or ushort type to double for delica use? Thank you!
