The RLEp format is a variant of the RLE compression (Run-length encoding) with the particularity of having 2 bits reserved to encode a pattern type and 6 bits for its length.
Pattern types:
| Val | Name | Desc. |
|---|---|---|
| [00¦len] | Default value | Repeat default value len times. The default value is either 0 or the first byte of the RLEp code. |
| [01¦len][value] | 1 byte | Repeat the next character len times. |
| [10¦len][value][value] | 2 bytes | Repeat the next two characters len times. |
| [11¦len][value][value]... | Uncompress | Followed by a list of non-compressed bytes of size len. |
