Created page with "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...."

New page

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:
{| class="wikitable"
! Val !! Name !! Desc.
|-
| <tt>[00¦Size]</tt> || Default value || Repeat default value X times. The default value is either 0 or the first byte of the RLEp code.
|-
| <tt>[01¦Size][value]</tt> || 1 byte || Repeat the next character X times.
|-
| <tt>[10¦Size][value][value]</tt> || 2 bytes || Repeat the next two characters X times.
|-
| <tt>[11¦Size][value][value]...</tt> || Uncompress || Followed by a list of non-compressed bytes of size X.
|}
