GSPLCI(3NCARG)

💅 GSPLCI — it's giving "polyline color index" ✨

okay bestie, so this is a page from the NCAR GRAPHICS manual, and it's literally about setting the polyline color index. That's it. That's the whole vibe. 🎀

🌸 NAME 🌸

GSPLCI (Polyline color index) — sets the polyline color index. periodt.

🦋 SYNOPSIS 🦋

CALL GSPLCI (COLI)

✨ C-BINDING SYNOPSIS ✨

for the C girlies, you're including this:

#include <ncarg/gks.h>

void gset_line_colr_ind(Gint line_colr_ind);

💖 DESCRIPTION 💖

• COLI (Integer, Input) — a color index. that's the whole thing she needs from you. just a number. iconic. 👑

🌈 USAGE 🌈

okay so here's the tea. every line you draw with calls to the GPL output primitive will be drawn with the color associated with index COLI — and it stays that way until GSPLCI gets called again and a new index is assigned. so like, it's sticky. she remembers. no cap. 💅

for all GKS output primitives, color is assigned using a color index. the color indices run from 0 to 255, where 0 is the background color index and 1 is the foreground color index. noted. 🫶

color values get associated with indices by calls to the GKS routine GSCR. and if you use a color index that has no user-assigned color value set in a GSCR call? then a device-dependent color value will be assigned to that index. so like, it's not undefined bestie, it's just ✨device-dependent✨ — meaning you don't get to pick, the device does. 🙈

🔥 ACCESS 🔥

to use GKS routines, load the NCAR GKS-0A library ncarg_gks. that's the whole access situation. go off. ⭐
