GSTXCI(3NCARG)

💖 GSTXCI — the NCAR Graphics girlies' guide to setting ur text color index 💖

okay so bestie, welcome to the GSTXCI page, straight out of the NCAR GRAPHICS manual (section 3NCARG, if u were wondering 🎀). this is the one that handles what color ur text is gonna be. it's giving palette control, it's giving main character energy, and honestly? it's so easy. let's go 🦋

✨ NAME ✨

GSTXCI — short for Set text color index — sets the text color index. that's it. that's the whole job. she's simple, she's iconic, she slays 💅

---

✨ SYNOPSIS ✨

the classic Fortran girlie way:

CALL GSTXCI (COLI)

---

✨ C-BINDING SYNOPSIS ✨

for the C girlies, u gotta pull in the header first:

#include <ncarg/gks.h>

void gset_text_colr_ind(Gint text_colr_ind);

no cap, that's the whole signature 🫶

---

✨ DESCRIPTION ✨

• COLI — (Integer, Input) — a color index. just a lil number, bestie, that's all she needs 🌸

---

✨ USAGE ✨

so here's the tea ☕ — every text string u draw with calls to the GTX output primitive is gonna get drawn with whatever color is associated with index COLI... and it stays that way until u call GSTXCI again and hand it a new index. she's loyal like that, she holds the vibe until u tell her otherwise 💖

and for all GKS output primitives, color gets assigned using a color index. the indices run from 0 to 255, where:

• 0 is the background color index 🌙
• 1 is the foreground color index ⭐

color values get hooked up to those indices by calling the GKS routine GSCR. and here's the lil plot twist 🫢 — if u use a color index that has no user-assigned color value set in a GSCR call, then a device-dependent color value gets assigned to that index. so basically the device picks for u. unpredictable queen behavior, lowkey 🙈

---

✨ ACCESS ✨

to use GKS routines, load the NCAR GKS-0A library ncarg_gks. load her up and ur good to go ✨
