The filter can reslice in all orthogonal planes such as sagittal, coronal and axial, and is also able to reslice an arbitrary oriented oblique plane. Curved planes are specified via an AbstractTransformGeometry as the input worldgeometry. Additionally the filter extracts the specified component of a multi-component input image. This is done only if the caller requests an mitk::Image output ('m_VtkOutputRequested' set to false). The default component to be extracted is '0'. The convenient workflow is: 1. Set an image as input. 2. Set the worldPlaneGeometry. This defines a grid where the slice is being extracted 3. And then start the pipeline. There are a few more properties that can be set to modify the behavior of the slicing. The properties are: - interpolation mode either Nearestneighbor, Linear or Cubic. - a transform this is a convenient way to adapt the reslice axis for the case that the image is transformed e.g. rotated. - time step the time step in a times volume. - the component to extract from a multi-component input image - vtkoutputrequested, to define whether an mitk::image should be initialized - resample by geometry whether the resampling grid corresponds to the specs of the worldgeometry or is directly derived from the input image By default the properties are set to: - interpolation mode Nearestneighbor. - a transform nullptr (No transform is set). - time step 0. - component 0. - resample by geometry false (Corresponds to input image). */ class MITKCORE_EXPORT ExtractSliceFilter : public ImageToImageFilter { public: mitkClassMacro(ExtractSliceFilter, ImageToImageFilter); itkFactorylessNewMacro(Self) itkCloneMacro(Self) mitkNewMacro1Param(Self, vtkImageReslice *); /** \brief Set the axis where to reslice at.*/ void SetWorldGeometry(const PlaneGeometry *geometry) { this->m_WorldGeometry = geometry; this->Modified(); } /** \brief Set the time step in the 4D volume */ void SetTimeStep(unsigned int timestep) { m_TimeStep = timestep; } unsigned int GetTimeStep() { return m_TimeStep; } /** \brief Set the component of an image to be extracted */ void SetComponent(unsigned int component) { m_Component = component; } /** \brief Set a transform for the reslice axes. * This transform is needed if the image volume itself is transformed.
