💖 set_color_blender 💖

okay bestie, welcome to the Allegro manual — yes, that Allegro, the game programming library 👑 — and today's main character is set_color_blender. she's a little function with big "make my pixels look cute" energy, and we're gonna learn her fr fr. no cap. 🎀

✨ NAME ✨

set_color_blender — enables a color blender mode 🦋

(and yeah she lives in the Allegro game programming library, she's one of those girls 💅)

🌸 SYNOPSIS 🌸

#include <allegro.h>

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

like. the whole vibe is right there. include the header, call the function, four ints, done. iconic. ⭐

💜 DESCRIPTION 💜

okay so here's the tea 🍓 — calling set_color_blender turns on a color blender mode that's built for combining translucent or lit truecolor pixels. that's literally her whole job.

but here's the part that makes her ✨special✨ and honestly a little bit mysterious:

  • she only applies the hue and saturation of the source image to the destination image.
  • she does NOT touch the luminance of the destination image. like, not even a little. luminance stays exactly where it was, untouched, unbothered, moisturised, in her lane. 🙈

so if you were expecting her to mess with brightness? she's not doing that. she said "i'm the color girl, not the lighting girl" and honestly? respect. 💅

ngl bestie, if you need the luminance to actually do something, this is not the function for you — she's very clear about her boundaries.

🔥 SEE ALSO 🔥

go read those too, they're her besties and they all hang out in the same group chat. 🫶

and that's the whole page, you ate it, periodt. 🎀✨

this lil rewrite was brought to you by Allegro, version 4.4.3, and the year it dropped — mwah 💋 go make something pretty with your pixels, bestie. 🦋💖
