✨ al_convert_mask_to_alpha ✨

okay bestie, welcome to the Allegro 5 API manual page for al_convert_mask_to_alpha — yes it's a long name, yes it's worth it, come sit with me 🫶

🌸 NAME 🌸

al_convert_mask_to_alpha — the Allegro 5 API function that takes your magic pink situation and makes it transparent, no cap 💅

---

🎀 SYNOPSIS 🎀

#include <allegro5/allegro.h>

void al_convert_mask_to_alpha(ALLEGRO_BITMAP *bitmap, ALLEGRO_COLOR mask_color)

like. two args. one function. we love a simple signature ✨

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function converts the given mask color into an alpha channel inside the bitmap. that's literally it, and it's iconic for it.

the vibe is: you've got one of those older 4.2-style bitmaps where the transparency was faked with a "magic pink" color, and you wanna bring it into the modern era as an alpha-ready bitmap. this is your girl for that. 🧚

no, seriously — that's the whole documented use case. legacy pink → alpha. glow up complete. periodt.

and that's the whole page, fr fr. this was al_convert_mask_to_alpha(3alleg5) from the Allegro reference manual — the same manual name in the header and the footer, matching on both ends like a cute little pair of bows 🎀 stay transparent (in the bitmap way) and go make something slay 💖✨
