GSET_LINE_COLR_IND(3NCARG)

✨ NAME ✨

gset_line_colr_ind (aka the Polyline color index glow-up) — bestie, it sets the polyline color index 💅

This one lives in the 3NCARG manual, so you already know it's giving classic NCAR Graphics energy 🎀

---

🌸 SYNOPSIS 🌸

#include <ncarg/gks.h>

void gset_line_colr_ind(Gint line_colr_ind);

---

💖 DESCRIPTION 💖

• line_colr_ind — (Input) a color index. That's it, that's the whole argument, she's lowkey simple like that 🙈

---

🦋 USAGE 🦋

Okay so here's the tea ☕ — every single line you draw by calling the gpolyline output primitive gets drawn in the color tied to the index line_colr_ind, and it keeps that vibe until you call gset_line_colr_ind again with a fresh index. No cap.

For all GKS output primitives, color is assigned using a color index. Those indices run from 0 to 255, where 0 is the background color index and 1 is the foreground color index. Iconic. 👑

Color values get associated with indices by calls to the GKS routine gset_colr_rep. And here's the part you need to know, fr fr: if you use a color index that has no user-assigned color value set in a gset_colr_rep call, then a device-dependent color value gets assigned to that index. So like… it'll be something, just not your something 😭

💌 okay that's the whole page, bestie — go set those color indices and slay 💅✨
