ImageGear .NET v25.1 - Updated
InverseFFT Method




ImageGear.Processing.Advanced Assembly > ImageGear.FreqIP Namespace > ImGearFrequencyProcessing Class : InverseFFT Method
ImGearComplexObject class object to be processed.
Specifies the method of scaling the result data.
Flag to indicate whether to use centered transform.
Performs an inverse Fast Fourier Transform.
Syntax
'Declaration
 
Public Shared Function InverseFFT( _
   ByVal value As ImGearComplexObject, _
   ByVal scalingMethod As ImGearFFTScalingMethods, _
   ByVal useCenteredTransform As Boolean _
) As ImGearComplexObject
'Usage
 
Dim value As ImGearComplexObject
Dim scalingMethod As ImGearFFTScalingMethods
Dim useCenteredTransform As Boolean
Dim value As ImGearComplexObject
 
value = ImGearFrequencyProcessing.InverseFFT(value, scalingMethod, 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

Remarks
This method performs an inverse Fast Fourier Transform.

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