```
byte[] bytes
```
    This field holds the whole byte array; In that it's redundant, as all chunks will have the same byte array. But have this byte array per chunk makes it easier to validate and pass around. And we won't have that many chunks, so those 8 bytes for the pointer (on 64-bit systems) don't matter.
  - chunkType
```
int chunkType
```
    The chunk type, see the CHUNK_??? constants.
  - crc
```
int crc
```
    The crc of the chunk data, as stored in the PNG stream.
  - start
```
int start
```
    The start index of the chunk data within bytes.
  - length
```
int length
```
    The length of the data within the byte array.
