<p><small>LZW</small> compression can be specified together |

with a <i>predictor</i> value. A predictor value of 2 causes |
|
111 |
each scanline of the output image to undergo horizontal |

differencing before it is encoded; a value of 1 forces each |
|
113 |
scanline to be encoded without differencing. LZW-specific |
|
114 |
options are specified by appending a |

‘‘:’’-separated list to the |
