3 Structure Examples

The LZXD bitstream is to be interpreted as a sequence of aligned 16-bit integers stored in the order least significant byte to most significant byte (little-endian words).

The only exception is the uncompressed data bytes stored in the uncompressed block interpreted as a sequence of bytes. The following example is a sample encoding sequence of a simple 3-byte text input "abc" encoded with a Block Type field value of 3 (uncompressed block).

Padding to restore word alignment

This is the raw hexadecimal compressed byte sequence of the encoded fields:
