'Usage

   ImGearFFTScalingMethods scalingMethod,
   bool useCenteredTransform
)

public: static ImGearComplexObject* ForwardFFT( 
   ImGearComplexObject* value,
   ImGearFFTScalingMethods scalingMethod,
   bool useCenteredTransform
) 

public:
static ImGearComplexObject^ ForwardFFT( 
   ImGearComplexObject^ value,
   ImGearFFTScalingMethods scalingMethod,
   bool useCenteredTransform
) 

Parameters

value

ImGearComplexObject class object to be processed.

scalingMethod

Specifies the method of scaling the result data.

useCenteredTransform

Flag to indicate whether to use centered transform.

Return Value

Note that the user must keep track how the transform is centered in the forward FFT in order to know how to de-center it during the inverse FFT, same goes for the scaling method.

Before using this method, like other frequency processing methods, InitializeFFTW method must be called first to initialize the support for FFTW.

Can be applied only to valid ImGearComplexObject class object.

ImGearFrequencyProcessingVerifier.CanApplyForwardFFT method can be called to check whether the operation can be performed or not.
