GSET_TEXT_COLR_IND(3NCARG)

✨ GSET_TEXT_COLR_IND ✨

okay bestie, welcome to the NCAR GRAPHICS corner of the universe 💖 this one lives in section 3NCARG and it is so simple it's honestly iconic.

🌸 NAME 🌸

gset_text_colr_ind (aka Set text color index) — it sets the text color index. that's it. that's the whole job. and it does it flawlessly. periodt. 💅

---

🦋 SYNOPSIS 🦋

#include <ncarg/gks.h>

void gset_text_colr_ind(Gint text_colr_ind);

---

🎀 DESCRIPTION 🎀

• text_colr_ind — (Input) a color index. just... a color index. give it a number, bestie, and it will be the number. 🌈

---

💜 USAGE 💜

okay so here's the tea ☕ — every single text string you draw with calls to the gtext output primitive is gonna be drawn with the color tied to whatever text_colr_ind you handed over, and it stays that way until you call gset_text_colr_ind again and assign a brand new index. no cap. it just keeps vibing with that color forever until you tell it otherwise. 👑

now, for all GKS output primitives, color gets assigned via a color index. the indices run from 0 to 255 — yes, all 256 of them, she's got range 💅 — and here's the mapping you need to remember:

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

color values get associated with those indices by calling the GKS routine gset_colr_rep. and if you use a color index that has no user-assigned color value set in a gset_colr_rep call? no worries, a device-dependent color value will get assigned to that index. the device decides. it's giving "mystery box" energy 🎁✨

🔥 ACCESS 🔥

to use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries. load them. both of them. don't skip, bestie 🫶

okay that's the whole page bestie, you ate it up 🌟 this came from the UNIX manual, March 1993 edition, and it's serving NCAR Graphics realness to this very day. mwah 💋🎀
