NAME

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

STATUS

       Halftone is obsolete.  It has been replaced by the CPCICA entry of the Conpack contouring
       package.

       Halftone continues to be provided for compatibility of early NCAR Graphics codes.  If you
       are writing new code, we suggest that you use CPCICA.

SYNOPSIS

       EZHFTN(Z,M,N) - draws a half-tone picture based upon a set of default options.
       HAFTON (Z,L,M,N,FLO,HI,NLEV,NOPT,NPRM,ISPV,SPVAL) - Draws a half-tone picture from data
       stored in a rectangular array with the intensity in the picture proportional to the data
       value.

ACCESS

       To use EZHFTN or HAFTON, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
