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

|
| CBlkInfo | | public CBlkInfo(int ulx, int uly, int w, int h, int nl)(Code) | | 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.
Parameters:
ulx - The uper-left x-coordinate
Parameters:
uly - The uper-left y-coordinate
Parameters:
w - Width of the code-block
Parameters:
h - Height of the code-block
Parameters:
nl - The number of layers |
| addNTP | | public void addNTP(int l, int newtp)(Code) | | Adds the number of new truncation for specified layer.
Parameters:
l - layer index
Parameters:
newtp - Number of new truncation points |
