public abstract class EntropyDecoder extends MultiResImgDataAdapter implements CBlkQuantDataSrcDec
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.
