<DD>Transforms coordinate points into direct positions stored as  values.
 This compression level has no effect if data are already stored as ,
 or if a more agressive compression is already in use (e.g. <A HREF="../../../../org/geotools/geometry/array/CompressionLevel.html#RELATIVE_AS_BYTES"><CODE>RELATIVE_AS_BYTES</CODE></A>).

<DL>
<DD>Transforms coordinate points into relative positions stored as  values.
 This compression mode replaces absolute positions (left handed image below) by relative
 positions (right handed image below), i.e. distances relative to the previous point.
 Assuming that all distances are of similar magnitude, distances can be coded in
  primitive type instead of <code>float</code>.

 Before the compression, the coordinates may be resampled (if needed) in order to obtain
 line segments of equal length. This compression level has no effect if the data are already
 compressed as relative positions.
