  - NULL_VALUE
```
private static final int NULL_VALUE
```
    and including NULL_VALUE. These values may not be used to represent the quantized and scaled floating point pixel values If lossy Hcompression is used, and the tiledImageOperation contains null values, then it is also possible for the compressed values to slightly exceed the range of the actual (lossless) values so we must reserve a little more space value used to represent undefined pixels
