• The InverseDCT Method computes the inverse Discrete Cosine Transform (IDCT) of the input data.
• The InverseDCTToImage Method computes the inverse Discrete Cosine Transform (IDCT) of the input image. The difference between this method and InverseDCT is that this method returns an ImGearPage Class as the result, using the default conversion type ImGearCoObjConvType.REAL.
