al_set_separate_bitmap_blender(3alleg5)

💅 al_set_separate_bitmap_blender 💅

okay bestie, so we're in the al_set_separate_bitmap_blender(3alleg5) page of the Allegro reference manual and honestly? it's giving "alpha channel gets its OWN blender" and I'm obsessed. 🎀

---

✨ NAME ✨

al_set_separate_bitmap_blender — it's the Allegro 5 API function that lets you pick a whole separate blending operation just for the alpha channel. two blenders, one call. main character energy fr fr. 👑

---

🦋 SYNOPSIS 🦋

#include <allegro5/allegro.h>

void al_set_separate_bitmap_blender(int op, int src, int dst, int alpha_op, int alpha_src, int alpha_dst)

---

🌸 DESCRIPTION 🌸

so basically, this is literally like al_set_bitmap_blender(3alleg5) — same vibe, same energy — BUT it also lets you specify a separate blending operation for the alpha channel. two ops. two sets of src/dst. she contains multitudes. 💖

and like, when is that useful? bestie, listen: if your target bitmap also has an alpha channel, and those two alpha channels need to be combined in a different way than the color components do — that's the moment. that's her moment. otherwise you'd be stuck smashing them together the same way as the colors and that's just not it. 🙈

⭐ SINCE ⭐

5.2.5

[Unstable API]: New API. 🚨

okay so real talk: she's marked Unstable API, and she's a New API. so like, use her, love her, but know she's still figuring herself out. no cap. 💀
