    ROIDeScaler Class
    In This Topic
    This class takes care of the de-scaling of ROI coefficients. The de-scaler works on a tile basis and any mask that is generated is for the current mask only

    Default implementations of the methods in 'MultiResImgData' are provided through the 'MultiResImgDataAdapter' abstract class.

    Sign-magnitude representation is used (instead of two's complement) for the output data. The most significant bit is used for the sign (0 if positive, 1 if negative). Then the magnitude of the quantized coefficient is stored in the next most significat bits. The most significant magnitude bit corresponds to the most significant bit-plane and so on.
