This class contains location of code-blocks' piece of codewords (there is one piece per layer) and some other information.

CBlkInfo

public class CBlkInfo

Name	Description
CBlkInfo(int, int, int, int, int)	Constructs a new instance with specified number of layers and code-block coordinates. The number corresponds to the maximum piece of codeword for one code-block.

Name	Description
ctp	The cumulative number of truncation points
h	Height of the code-block
len	Length of each piece of code-block's codewords
msbSkipped	The number of most significant bits which are skipped for this code-block (= Mb-1-bitDepth).
ntp	The number of truncation point for each layer
off	Offset of each piece of code-block's codewords in the file
pktIdx	Index of the packet where each layer has been found
segLen	The length of each segment (used with regular termination or in selective arithmetic bypass coding mode)
ulx	Upper-left x-coordinate of the code-block (relative to the tile)
uly	Upper-left y-coordinate of the code-block (relative to the tile)
w	Width of the code-block

Name	Description
ToString()	Object information in a string.
addNTP(int, int)	Adds the number of new truncation for specified layer.
