Hi Miklos,
Regarding your suggestion to set my input image by SetInput(...), and get
the same error ...
In order to be clear, I insert again the important parts of my code,
including some changes according to your suggestion.
void myModule::GenerateData()
{
mitk::Image::ConstPointer image = this->GetInput(0);
mitk::ImagePointer outputImage = this->GetOutput();
AccessIntegralPixelTypeByItk_n(image, MyFunction, (m_inputVal1,
m_inputVal2, outputImage))
}
The following function manipulates some itk's filters on the (four) input
images:
template < typename TPixel, unsigned int VImageDimension >
void myModule::MyFunction ( itk::Image <TPixel, VImageDimension>* image,
int val1, int val2, mitk::Image::Pointer outputImage)
{
typedef itk::Image <TPixel, VImageDimension> ImageType;
ImageType::Pointer itkImage_1;
// I did that to all of the N images
mitk::CastToImage ( m_inputImage_1, itkImage_1);
// I did that to all of the N images
mitk::CastMitkImage ( itkImage_1, outputImage);
}
myModule.h
=========
class myModule : public mitk:ImageToImageFilter
{
public:
template<typename TPixel, unsigned int VImageDimension>
void MyFunction (itk::Image<TPixel, VImageDimension>* inputImage, int,
int, mitk::Image::Pointer outputImage)
mitk::Image::ConstPointer m_inputImage_1;
mitk::Image::ConstPointer m_inputImage_2;
mitk::Image::ConstPointer m_inputImage_3;
mitk::Image::ConstPointer m_inputImage_4;
etc ...
}
