Class DecLyrdCBlk


  • public class DecLyrdCBlk
    extends CodedCBlk
    This class stores coded (compressed) code-blocks that are organized in layers. This object can contain either all the data of the code-block (i.e. all layers), or a subset of all the layers that make up the whole compressed-code-block. It is applicable to the decoder engine only. Some data of the coded-block is stored in the super class, see CodedCBlk.

    A code-block may have its progressive attribute set (i.e. the 'prog' flag is true). If a code-block is progressive then it means that more data for it may be obtained for an improved quality. If the progressive flag is false then no more data is available from the source for this code-block.

      • ulx

        public int ulx
        The horizontal coordinate of the upper-left corner of the code-block
      • uly

        public int uly
        The vertical coordinate of the upper left corner of the code-block
      • w

        public int w
        The width of the code-block
      • h

        public int h
        The height of the code-block
      • dl

        public int dl
        The coded (compressed) data length. The data is stored in the 'data' array (see super class).
      • prog

        public boolean prog
        The progressive flag, false by default (see above).
      • nl

        public int nl
        The number of layers in the coded data.
      • ftpIdx

        public int ftpIdx
        The index of the first truncation point returned
      • nTrunc

        public int nTrunc
        The total number of truncation points from layer 1 to the last one in this object. The number of truncation points in 'data' is 'nTrunc-ftpIdx'.
      • tsLengths

        public int[] tsLengths
        The length of each terminated segment. If null then there is only one terminated segment, and its length is 'dl'. The number of terminated segments is to be deduced from 'ftpIdx', 'nTrunc' and the coding options. This array contains all terminated segments from the 'ftpIdx' truncation point, upto, and including, the 'nTrunc-1' truncation point. Any data after 'nTrunc-1' is not included in any length.
