Thanks:
Thanks to C. Charles Law who developed this class.
vtkImageFourierFilter is a class of filters that use complex numbers this superclass is a container for methods that manipulate these structure including fast Fourier transforms. Complex numbers may become a class. This should really be a helper class.

Member Function Documentation

vtkImageFourierFilter* vtkImageFourierFilter::New   [static]
 

Construct an instance of vtkImageDecomposeFilter filter with default dimensionality 3.

Reimplemented from vtkImageDecomposeFilter.

Reimplemented in vtkImageFFT, and vtkImageRFFT.

virtual const char* vtkImageFourierFilter::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageDecomposeFilter.

Reimplemented in vtkImageFFT, and vtkImageRFFT.

int vtkImageFourierFilter::IsTypeOf const char *    type [static]
 

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageDecomposeFilter.

Reimplemented in vtkImageFFT, and vtkImageRFFT.

virtual int vtkImageFourierFilter::IsA const char *    type [virtual]
 

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageDecomposeFilter.

Reimplemented in vtkImageFFT, and vtkImageRFFT.

vtkImageFourierFilter* vtkImageFourierFilter::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageDecomposeFilter.

Reimplemented in vtkImageFFT, and vtkImageRFFT.

void vtkImageFourierFilter::ExecuteFft vtkImageComplex   in,
vtkImageComplex   out,
int    N
 

This function calculates the whole fft of an array. The contents of the input array are changed. (It is engineered for no decimation)

void vtkImageFourierFilter::ExecuteRfft vtkImageComplex   in,
vtkImageComplex   out,
int    N
 

This function calculates the whole fft of an array. The contents of the input array are changed. (It is engineered for no decimation)
