- Field Detail
  - packetIdx
```
public int packetIdx
```
    Index of the packet
  - layerIdx
```
public int layerIdx
```
    The layer associated with the current code-block in this packet.
  - cbOff
```
public int cbOff
```
    The code-block offset in the codestream (for this packet)
  - cbLength
```
public int cbLength
```
    The length of the code-block in this packet (in bytes)
  - segLengths
```
public int[] segLengths
```
    The length of each terminated segment in the packet. The total is the same as 'cbLength'. It can be null if there is only one terminated segment, in which case 'cbLength' holds the legth of that segment
  - numTruncPnts
```
public int numTruncPnts
```
    The number of truncation points that appear in this packet, and all previous packets, for this code-block. This is the number of passes that can be decoded with the information in this packet and all previous ones.
