image_texfilter(3)

✨ NAME ✨

image_texfilter — switch object video filtering mode. Yep, this is the image_texfilter(3) page from the Arcan Lua API, bestie 💅

---

🫶 SYNOPSIS 🫶

nil
image_texfilter( vid, mode )

---

💅 DESCRIPTION 💅

Okay so every object inherits a global default filtering mode when it gets created. Periodt. 🎀

This function lets you override that mode for individual objects, no cap.

The valid filtering modes are: FILTER_NONE, FILTER_LINEAR, FILTER_BILINEAR, FILTER_TRILINEAR ✨

---

🧚 NOTES 🧚

1. Filtering mode is connected to the gl storage, and the options to share storage between objects through instancing or explicit sharing will retain this property. Lowkey important, so don't forget it 💖

🌈 EXAMPLE 🌈

Here's the example, exactly as given:

function image_texfilter0()
      a = load_image("test.png");
      b = load_image("test.png");
      c = load_image("test.png");
      d = load_image("test.png");
      w = VRESW * 0.5;
      h = VRESW * 0.5;
      resize_image({a,b,c,d}, w, h);
      show_image({a,b,c,d});
      move_image(b, w, 0);
      move_image(c, 0, h);
      move_image(d, w, h);
      image_texfilter(a, FILTER_NONE);
      image_texfilter(b, FILTER_LINEAR);
      image_texfilter(c, FILTER_BILINEAR);
      image_texfilter(d, FILTER_TRILINEAR);
end
