  53 <p><i>tiffsv</i> saves all or part of the framebuffer in a
  54 file using the Tag Image File Format, Revision 6.0. By
  55 default, the image is saved with data samples packed
  56 (<i>PlanarConfiguration</i>=1), compressed with the
  57 Lempel-Ziv &amp; Welch algorithm (<i>Compression</i>=5), and
  58 with each strip no more than 8 kilobytes. These
  59 characteristics can be overridden, or explicitly specified
  60 with the options described below.</p>

 112 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
