ImageGear .NET v25.2 - Updated
InverseDCTToImage Method




ImageGear.Processing.Advanced Assembly > ImageGear.FreqIP Namespace > ImGearFrequencyProcessing Class : InverseDCTToImage Method
An ImGearComplexObject class object to be transformed.
Computes the inverse Discrete Cosine Transform (IDCT) of the input data.
Syntax
'Declaration
 
Public Shared Function InverseDCTToImage( _
   ByVal value As ImGearComplexObject _
) As ImGearPage
'Usage
 
Dim value As ImGearComplexObject
Dim value As ImGearPage
 
value = ImGearFrequencyProcessing.InverseDCTToImage(value)
public static ImGearPage InverseDCTToImage( 
   ImGearComplexObject value
)
public: static ImGearPage* InverseDCTToImage( 
   ImGearComplexObject* value
) 
public:
static ImGearPage^ InverseDCTToImage( 
   ImGearComplexObject^ value
) 

Parameters

value
An ImGearComplexObject class object to be transformed.

Return Value

Remarks
This method computes the inverse Discrete Cosine Transform (IDCT) of the input data. The difference between this method and InverseDCT method is that this one returns an ImageGear.Core.ImGearPage class as the result, using the default conversion type ImGearCoObjConvType.REAL.

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