| 57 | * Block channels can be used to store compressed and buffer data: |
| 58 | * 1. For compressed formats, only the data channel is used and its size |
| 59 | * is equal to that of a singular block in the compression scheme. |
| 60 | * 2. For buffer formats, only the data channel is used and its size is |
