makecol8(3alleg4)

💖 makecol8 💖

okay bestie, so this is a page from the Allegro manual (that's the Allegro game programming library, mwah) and it's literally all about turning your cute little RGB vibes into actual display-dependent pixel formats. also known as makecol8, makecol15, makecol16, makecol24, and makecol32. yeah. five whole icons in one page. we love a multipack 🎀

✨ NAME ✨

makecol8, makecol15, makecol16, makecol24, makecol32 — these bad boys convert an RGB value into a display dependent pixel format. part of the Allegro game programming library, no cap.

🦋 SYNOPSIS 🦋

#include <allegro.h>

int makecol8(int r, int g, int b);

int makecol15(int r, int g, int b);

int makecol16(int r, int g, int b);

int makecol24(int r, int g, int b);

int makecol32(int r, int g, int b);

like… five functions, same energy, different depth. pick your fighter 💅

🌸 DESCRIPTION 🌸

so here's the tea. these functions take colors from a hardware independent form — that's your red, green, and blue values, each one ranging 0-255 — and convert them into various display dependent pixel formats. it's giving glow-up but for numbers. ✨

converting to 15, 16, 24, or 32-bit formats? literally only takes a few shifts, so it's fairly efficient. slay, no notes.

but converting to an 8-bit color?? okay so that one involves searching the palette to find the closest match, which is quite slow — unless you've set up an RGB mapping table. (see below, bestie, i got you 👇)

example time, because we're visual learners:

/* 16 bit color version of green. */
int green_color = makecol16(0, 255, 0);

see how clean that is? 0, 255, 0. that's green. that's the whole vibe. 💚

💜 RETURN VALUE 💜

returns the requested RGB triplet, but in the specified color depth. so like… the same color, just speaking a different dialect. 🫶
