rgb_map(3alleg4)

✨ NAME ✨

okay bestie, meet rgb_map from the Allegro manual (3alleg4). It's the Look up table to speed up reducing RGB values to palette colors. It lives in the Allegro game programming library, and it's here to make your color math not drag. main character energy, honestly. 💅

🌸 SYNOPSIS 🌸

you literally just need this:

#include <allegro.h>

extern RGB_MAP *rgb_map;

that's it. iconic.

💖 DESCRIPTION 💖

so to speed up reducing RGB values to 8-bit paletted colors, Allegro uses a 32k lookup table — that's 5 bits for each color component, periodt. ✨

You must set up this table before using the gouraud shading routines. not optional, bestie, no cap. And if present, the table will also vastly accelerate makecol8() and some create_*_table() functions. the way it just carries your whole palette workflow? highkey obsessed. iykyk. 🦋

RGB tables can be precalculated with the rgbmap utility, or generated at runtime with create_rgb_table(). pick your method, both are valid. slay. 💖
