Halftone(3NCARG)

✨ Halftone ✨

okay so bestie, welcome to the NCAR GRAPHICS girlies' corner 💅 this one is Halftone(3NCARG) and it's a whole vibe — it's a utility for drawing half-tone pictures where the gray scale level is proportional to the value in a two dimensional array. yes literally. shades = numbers. iconic behavior honestly 🎀

---

💀 STATUS 💀

Halftone is obsolete. not "lowkey old", not "a little crusty" — obsolete. it has been replaced by the CPCICA entry of the Conpack contouring package. rip to a real one 🫶

it continues to be provided for compatibility of early NCAR Graphics codes. so if you're writing new code, bestie, we suggest that you use CPCICA. that's the move. no cap. ✨

🌸 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.

so like, EZHFTN(Z,M,N) is the easy one — it draws a half-tone picture based upon a set of default options. defaults, periodt. 💖

and HAFTON (Z,L,M,N,FLO,HI,NLEV,NOPT,NPRM,ISPV,SPVAL) is the full-send version — it draws a half-tone picture from data stored in a rectangular array, with the intensity in the picture proportional to the data value. main character energy fr fr 👑

🦋 ACCESS 🦋

to use EZHFTN or HAFTON, you load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order. that order matters, bestie, don't play with it 🙈

and that's the whole page, bestie ✨ this edition came out of the UNIX manual, dated March 1993 — yes, 1993, she's vintage, she's a classic, she's literally older than the internet's whole aesthetic and she still serves 💜 go use CPCICA tho, ily 🫶🍓
