logicalTarget

JP2LogicalTarget logicalTarget

Is the logical target

precinctsQualityLayers

protected java.util.HashMap<java.lang.Long,java.util.ArrayList<int[][][]>> precinctsQualityLayers

It is a hash table that storages the number of coding passes for each quality layer. The key of the hash is the unique data-bin identifier calculated as:
I = t + (c + s x num_components) + num_tiles
where,
I is the unique identifier of the precinct within its codestream;
t is the index (startin from 0) of the tile to which the precinct belongs;
c is the index (starting from 0) of the image component to which the precinct belongs;
s is a sequence number which identifies the precinct within its tile-component.
Values of the hash table are the number of coding passes from a precinct belonging to a quality layer.
