    This function computes the inverse Discrete Cosine Transform of the input HIGCOMPLEXOBJ data.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_FIP_DCT_inverse(
            HIGCOMPLEXOBJ hIGComplexObj, 
            LPHIGCOMPLEXOBJ lphIGComplexObjOut
    );
    

    Arguments:

    Name Type Description
    hIGComplexObj HIGCOMPLEXOBJ HIGCOMPLEXOBJ handle of data to be processed.
    lphIGComplexObjOut LPHIGCOMPLEXOBJ HIGCOMPLEXOBJ handle of result data.

    Return Value:

    Returns the number of ImageGear errors that occurred during this function call.

    Supported Raster Image Formats:

    All pixel formats supported by HIGCOMPLEXOBJ object. See IG_FIP_co_obj_create.

    Sample:

    FreqIP

    Example:

     
    Copy Code
    HIGCOMPLEXOBJ hIGComplexObj;             /* HIGCOMPLEXOBJ handle of input data */
    HIGCOMPLEXOBJ hIGComplexObjOut;         /* HIGCOMPLEXOBJ handle of output data */
    ...
