{quote}
An indication of when to increase the code length. If the value of this entry
is 0, code length increases are postponed as long as possible. If the value is
1, code length increases occur one code early. This parameter is included
because LZW sample code distributed by some vendors increases the code length
one code earlier than necessary. Default value: 1.
