Static p5_sys::global::loadPixels

pub static loadPixels: LoadPixelsInternalType

Loads the pixel data for the display window into the pixels[] array. This function must always be called before reading from or writing to pixels[]. Note that only changes made with set() or direct manipulation of pixels[] will occur.

Examples

let img;
function preload() {
  img = loadImage('assets/rockies.jpg');
}

function setup() {
  image(img, 0, 0, width, height);
  let d = pixelDensity();
  let halfImage = 4 * (width * d) * (height * d / 2);
  loadPixels();
  for (let i = 0; i < halfImage; i++) {
    pixels[i + halfImage] = pixels[i];
  }
  updatePixels();
}
