[Insight-users] Problem when using seriesreader together with series writer

[Luis Ibanez]

Hi Wen,

The message:

 >
 > error C2440: 'initializing' : cannot convert from 
'itk::Image<TPixel,VImageDimension> *' to 'itk::SmartPointer<TObjectType>'
 >


Is a compilation error.


The error indicates that you are not using a consistent
declaration of image types.


Could you please post to the list the *exact* content of
the line of code where you are seeing this error ?



     Thanks



        Luis
