Detailed Description

template<typename TOutputImage>
class itk::VTKImageImport< TOutputImage >

Connect the end of an VTK pipeline to an ITK image pipeline.

VTKImageImport can be used at the beginning of an ITK image pipeline to connect with a VTK pipeline that ends with vtkImageExport. Callbacks provided by VTKImageImport are registered with vtkImageExport to connect the pipeline execution together. Once connected, update requests coming through the ITK pipeline are automatically propagated to the VTK pipeline.

Note that the VTK images are assumed to be of 1, 2, or 3 dimensions. Scalar value types can be one of: float, double, char, unsigned char, short, unsigned short, int, unsigned int, long, unsigned long. The images must have pixel types with one component.

Member Function Documentation

template<typename TOutputImage> virtual void itk::VTKImageImport< TOutputImage >::GenerateData (   )  [protected, virtual]

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead. See also: ThreadedGenerateData() Reimplemented from itk::ImageSource< TOutputImage >.

template<typename TOutputImage> virtual void itk::VTKImageImport< TOutputImage >::GenerateOutputInformation (   )  [protected, virtual]

Generate the information decribing the output data. The default implementation of this method will copy information from the input to the output. A filter may override this method if its output will have different information than its input. For instance, a filter that shrinks an image will need to provide an implementation for this method that changes the spacing of the pixels. Such filters should call their superclass' implementation of this method prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information. Reimplemented from itk::ProcessObject.

template<typename TOutputImage> virtual void itk::VTKImageImport< TOutputImage >::UpdateOutputInformation (   )  [protected, virtual]

Update the information decribing the output data. This method transverses up the pipeline gathering modified time information. On the way back down the pipeline, this method calls GenerateOutputInformation() to set any necessary information about the output data objects. For instance, a filter that shrinks an image will need to provide an implementation for GenerateOutputInformation() that changes the spacing of the pixels. Such filters should call their superclass' implementation of GenerateOutputInformation prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information.
