> The image in the attached PDF can't be decoded (IndexOutOfBoundsException),
> The reason is that the EarlyChange decode param is set to 0:
> {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.
