💖 set_luminance_blender(3) 💖

okay bestie, sit DOWN, because we're talking about set_luminance_blender — straight out of the Allegro manual, aka the Allegro game programming library. this one's a little legend and she's about to change your whole lighting game, no cap ✨

🌸 NAME 🌸

set_luminance_blender — enables a luminance blender mode. like, that's the whole job. Allegro game programming library, mwah 💅

🎀 SYNOPSIS 🎀

#include <allegro.h>

void set_luminance_blender(int r, int g, int b, int a);

look at her. four little ints. r, g, b, and a. iconic behavior fr fr 🫶

🦋 DESCRIPTION 🦋

so what does she actually DO? she enables a luminance blender mode — specifically for combining translucent or lit truecolor pixels. think glow-ups, think mood lighting, think your sprites catching feelings and light at the same time 😭

here's the tea: it applies the luminance of the source to the destination. and the part everyone asks about — the colour of the destination is not affected 🎀

read that again. the destination keeps its own colour. we're only moving the brightness around. it's giving spotlight, not paint bucket. periodt 💅

🌈 SEE ALSO 🌈

• set_trans_blender(3) — her sister, the transparency one
• drawing_mode(3) — where the whole blender situation actually gets switched on, iykyk

ngl if you're out here doing lit truecolor pixel stuff, this is your girl. go off 🧚

and that's the whole page, bestie!! 💖 brought to you by the Allegro manual, version 4.4.3 — yes, 4.4.3, she's a classic, she ate and left no crumbs. go make something gorgeous with your luminance 🌸✨👑
