| Subband | 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). |
| WTDecompSpec | This class holds the decomposition type to be used in each part of the image; the default one, the component specific ones, the tile default ones and the component-tile specific ones. The decomposition type identifiers values are the same as in the codestream. The hierarchy is: At the moment tiles are not supported by this class. |
