al_draw_bitmap_region(3alleg5)

✨ NAME ✨

bestie, this is al_draw_bitmap_region — the Allegro 5 API function that lets you yeet just a lil piece of a bitmap onto the target bitmap 💖

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

void al_draw_bitmap_region(ALLEGRO_BITMAP *bitmap,
   float sx, float sy, float sw, float sh, float dx, float dy, int flags)

---

🎀 DESCRIPTION 🎀

okay so picture this: you have a whole bitmap, right, and you do NOT want the whole thing. you want a region of it. a lil cropped slice. the moment. and you want that slice drawn onto the target bitmap. that's literally what this does, no cap 🦋

here's the breakdown of every single argument, because we don't gatekeep:

• sx — source x 💅
• sy — source y 💅
• sw — source width (aka how wide the region you're blitting is)
• sh — source height (aka how tall the region you're blitting is)
• dx — destination x
• dy — destination y
• flags — exactly the same as the ones for al_draw_bitmap(3alleg5), periodt

🌈 and fr fr, go read al_draw_bitmap(3alleg5) because it has a whole note about the restrictions on which bitmaps can be drawn where. that's not optional lore, that's required reading, bestie.
