Thank you for tying to help me.
Casting to the exact input image type is what I tryied to implement (after
checking it with the debugger).
Actually, I ran it again with these commands, but received the mentioned
error.
typedef unsigned short InputPixelType;
typedef itk::Image < InputPixelType, 3 > InputImageType;
itk::Image< InputPixelType, 3>::Pointer itkImage_1;
- I'd like to mention again that the error accepted in the following
command:
myModulePointer->Update(); // a command at the file: MyPlugInView.cpp
- My application was generated by the CTK's generator and I just changed
that application in order to get a multiple number of input images (instead
of one input image, as the generator implemented).
