ComplexImages

ComplexImages() performs complex mathematics on an image sequence.

The format of the ComplexImages method is:

MagickBooleanType ComplexImages(Image *images,const ComplexOperator op,
  ExceptionInfo *exception)

A description of each parameter follows:

image: the image.
op: A complex operator.
exception: return any errors or warnings in this structure.

ForwardFourierTransformImage

ForwardFourierTransformImage() implements the discrete Fourier transform (DFT) of the image either as a magnitude / phase or real / imaginary image pair.

The format of the ForwardFourierTransformImage method is:

Image *ForwardFourierTransformImage(const Image *image,
  const MagickBooleanType modulus,ExceptionInfo *exception)

A description of each parameter follows:

image: the image.
modulus: if true, return as transform as a magnitude / phase pair otherwise a real / imaginary image pair.
exception: return any errors or warnings in this structure.

InverseFourierTransformImage

InverseFourierTransformImage() implements the inverse discrete Fourier transform (DFT) of the image either as a magnitude / phase or real / imaginary image pair.

The format of the InverseFourierTransformImage method is:

Image *InverseFourierTransformImage(const Image *magnitude_image,
  const Image *phase_image,const MagickBooleanType modulus,
  ExceptionInfo *exception)

A description of each parameter follows:

magnitude_image: the magnitude or real image.
phase_image: the phase or imaginary image.
modulus: if true, return transform as a magnitude / phase pair otherwise a real / imaginary image pair.
exception: return any errors or warnings in this structure.
