ImageGear21.Processing.Advanced Assembly > ImageGear.FreqIP Namespace > ImGearFrequencyProcessing Class : ForwardDCT Method |
'Declaration Public Shared Function ForwardDCT( _ ByVal value As ImGearComplexObject _ ) As ImGearComplexObject
'Usage Dim value As ImGearComplexObject Dim value As ImGearComplexObject value = ImGearFrequencyProcessing.ForwardDCT(value)
public static ImGearComplexObject ForwardDCT( ImGearComplexObject value )
public: static ImGearComplexObject* ForwardDCT( ImGearComplexObject* value )
public: static ImGearComplexObject^ ForwardDCT( ImGearComplexObject^ value )
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.CanApplyForwardDCT method can be called to check whether the operation can be performed or not.
