[Insight-users] Problems with fixedReader->Update();

[motes motes]

Ok in the followup its recommended to change the type of PixelType to:

typedef unsigned char  PixelType;

or

typedef unsigned short   PixelType;


But I already declared it as :

typedef unsigned char  PixelType;

and I have also tried:

typedef unsigned short   PixelType;

but I still get the same error, any ideas?
