Detailed Description

Superclass that implements complex numbers.

Date:

2000/12/10 20:09:06

Revision:

1.25

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)

void vtkImageFourierFilter::operator= (  const vtkImageFourierFilter &    )  [inline, protected]

Definition at line 142 of file vtkImageFourierFilter.h.

void vtkImageFourierFilter::ExecuteFftStep2 (  vtkImageComplex *    p_in, vtkImageComplex *    p_out, int    N, int    bsize, int    fb )  [protected]

void vtkImageFourierFilter::ExecuteFftStepN (  vtkImageComplex *    p_in, vtkImageComplex *    p_out, int    N, int    bsize, int    n, int    fb )  [protected]

void vtkImageFourierFilter::ExecuteFftForwardBackward (  vtkImageComplex *    in, vtkImageComplex *    out, int    N, int    fb )  [protected]
