     ClassDescription
    ClassSubband This abstract class represents a subband in a bidirectional tree structure that describes the subband decomposition for a wavelet transform. This class is implemented by the SubbandAn and SubbandSyn classes, which are for the analysis and synthesis sides respectively.

    The element can be either a node or a leaf of the tree. If it is a node, it has 4 descendants (LL, HL, LH and HH). If it is a leaf, it has no descendant.

    The tree is bidirectional. Each element in the tree structure has a "parent", which is the subband from which the element was obtained by decomposition. The only exception is the root element which, for obvious reasons, has no parent (i.e. it is null).

     StructureDescription
    StructureFilterTypes_Fields This interface defines the identifiers for the different types of filters that are supported.

    The identifier values are the same as those used in the codestream syntax, for the filters that are defined in the standard.

    StructureWaveletFilter_Fields This interface defines how a wavelet filter implementation should present itself. This interface defines only the commonalities between the analysis and synthesis filters. The AnWTFilter and SynWTFilter classes provide the specifics of analysis and synthesis filters.

    Both analysis and filters must be able to return the extent of the negative and positive support for both synthesis and analysis sides. This simplifies the sue of some functionalities that need extra information about the filters.

    StructureWaveletTransform_Fields This interface defines how a forward or inverse wavelet transform should present itself. As specified in the ImgData interface, from which this class inherits, all operations are confined to the current tile, and all coordinates are relative to it.

    The definition of the methods in this interface allows for different types of implementation, reversibility and levels of decompositions for each component and each tile. An implementation of this interface does not need to support all this flexibility (e.g., it may provide the same implementation type and decomposition levels for all tiles and components).
