GSET_FILL_COLR_IND(3NCARG)

💅 GSET_FILL_COLR_IND — bestie edition ✨

okay so you're in the NCAR GRAPHICS cinematic universe (the 3NCARG girlies know 🌸) and you need to tell your fill areas what color to wear. that's literally this function. her government name is gset_fill_colr_ind, aka Set fill area color index, and what she does is... set the fill area color index. iconic, no notes 💖

✨ SYNOPSIS ✨

#include <ncarg/gks.h>

void gset_fill_colr_ind(Gint fill_colr_ind);

like. she's a one-argument girlie. that's it. that's the whole vibe 🫶

🎀 DESCRIPTION 🎀

• fill_colr_ind — (Input) — a color index. that's the whole thing. you hand her a number, she takes it as the color index, slay 💅

🌈 USAGE 🌈

okay so here's the tea, bestie 🍓 every single filled area you draw with calls to the gfill_area output primitive is gonna get drawn in the color tied to the index fill_colr_ind — and it keeps doing that until you call gset_fill_colr_ind again with a new index. she's loyal like that. no cap 💜

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

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

(ok the second one is foreground, i just wanted both to sparkle ✨)

you link actual color values to indices by calling the GKS routine gset_colr_rep. and listen — 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's not gonna be undefined, it's just gonna be whatever your device feels like doing that day 😭 not you rolling the dice on your own palette 🙈

🔑 ACCESS 🔑

to use the GKS C-binding routines, you gotta load the ncarg_gks and ncarg_c libraries. both. don't skip one, that's giving "linker error main character energy" 💀
