public interface Markers
```
This interface defines the values of the different markers in the JPEG 2000 codestream. There are 16 bit values, always appearing in big-endian (most significant byte first) and byte-aligned in the codestream. This interface also defines some other constants such as bit-masks and bit-shifts.
