[Insight-users] CastImageFilter error

[Dan Mueller]

Hi,

It seems you have a type mismatch between
VTKImageToImageType::OutputImageType and CasterType::InputImageType.

Try changing
    typedef itk::CastImageFilter< FixedImageType, InternalImageType >
CasterType;
to
    typedef itk::CastImageFilter<
VTKImageToImageType::OutputImageType, InternalImageType > CasterType;
or
    typedef itk::CastImageFilter< ImageType, InternalImageType > CasterType;

Regards, Dan
