6       Halftone - is a utility for drawing half-tone pictures in which the
7       gray scale level is proportional to the value in a two dimensional
8       array.

STATUS

11       Halftone is obsolete.  It has been replaced by the CPCICA entry of the
12       Conpack contouring package.
13
14       Halftone continues to be provided for compatibility of early NCAR
15       Graphics codes.  If you are writing new code, we suggest that you use
16       CPCICA.

21       HAFTON (Z,L,M,N,FLO,HI,NLEV,NOPT,NPRM,ISPV,SPVAL) - Draws a half-tone
22       picture from data stored in a rectangular array with the intensity in
23       the picture proportional to the data value.
