Member Function Documentation

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion DataObject output  )  [protected, virtual]
 

GradientMagnitudeRecursiveGaussianImageFilter produces all of the output. Therefore, it needs to provide an implementation of EnlargeOutputRequestedRegion().

Reimplemented from itk::ProcessObject.

template<typename TInputImage, typename TOutputImage = TInputImage>
void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateData void   )  [protected, virtual]

Reimplemented from itk::ImageSource< TOutputImage >.

template<typename TInputImage, typename TOutputImage = TInputImage>
virtual void itk::GradientMagnitudeRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion  )  throw (InvalidRequestedRegionError) [protected, virtual]
 

GradientMagnitudeRecursiveGaussianImageFilter needs all of the input to produce an output. Therefore, GradientMagnitudeRecursiveGaussianImageFilter needs to provide an implementation for GenerateInputRequestedRegion in order to inform the pipeline execution model.
