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Halftone is obsolete. It has been replaced by the CPCICA entry of the Conpack contouring package.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