switch_default_imageproc(3)

💅 switch_default_imageproc(3) — the Arcan Lua API glow-up

okay so bestie, welcome to the Arcan Lua API corner of the world ✨ this is switch_default_imageproc(3) and she's literally the vibe-setter for how your images get post-processed. pull up a chair 🎀

---

✨ NAME ✨

switch_default_imageproc — sets the default image post-processing mode, no cap 💖

---

✨ SYNOPSIS ✨

nil
switch_default_imageproc( procmode )

so she hands you back nil (iconic, lowkey humble of her 🫶) and you pass in exactly one thing: procmode.

---

✨ DESCRIPTION ✨

this is the function you call when you want to tell everyone "hey, this is how we're doing images from now on" 👑

the accepted values are, and I'm quoting the source of truth here:

• IMAGEPROC_NORMAL — where the loaded image will be stored without any additional postprocessing. clean, unbothered, main character energy 💅
• IMAGEPROC_FLIPH — where the image will be flipped over the x-axis (so y- row order will be inverted). flip her upside down, she slays either way 🦋

that's it, that's the whole menu. two options, both iconic, choose wisely 🌸

---

✨ EXAMPLE ✨

ok so here's the little demo script, and yes I'm giving it to you character for character because she's precious:

function switch_default_imageproc0()
      switch_default_imageproc(IMAGEPROC_FLIPH);
      a = load_image("test.png");
      switch_default_imageproc(IMAGEPROC_NORMAL);
      b = load_image("test.png");
      show_image({a,b});
      local props = image_surface_properties(b);
      move_image(b, b.width, b.height);
end

see the way she flips it, loads a, sets it back to normal, loads b, shows them both, then pulls props off b and moves b? chef's kiss 😭🔥

---

✨ MISUSE ✨

now for the part where we learn what NOT to do 🙈 first offender:

function switch_default_imageproc0()
      switch_default_imageproc("test1");
end

yeah... a string. not it bestie 💀

---

✨ MISUSE ✨

and the second one, because apparently we're doing a whole series:

function switch_default_imageproc1()
      switch_default_imageproc(200);
end

a raw 200. nope, we're passing those IMAGEPROC_ constants, not vibes 🌈

fr fr, stick to IMAGEPROC_NORMAL and IMAGEPROC_FLIPH and you can't go wrong ✨
