This class contains the maxshift scaling value for each tile-component. The scaling values used are calculated in the ROIScaler class

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

       <p>Default implementations of the methods in 'MultiResImgData' are provided
       through the 'MultiResImgDataAdapter' abstract class.</p><p>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.</p>
