Envelhecimento de Imagem

Para fazer esse código usei alguns comandos do anterior (fazer o upload de imagem e deixá-la com tons de cinza).

Para deixar em tons de sépia, usei o comando tint() que pinta uma imagem da cor escolhida, e para gerar o ruído, usei 2 "for", um com tons de laranja e o outro preto, eles geravam centenas de círculos minúsculos aleatórios em toda imagem, gerando assim, um noise.

Código:

PImage imgOriginal;

PImage imgCopia = createImage(800, 800, RGB);

float r;

int pos;

void setup() {

 size(800, 800);

 imgOriginal = loadImage("original.jpg");

 for (int x = 0; x < 800; x++) {

 for (int y = 0; y < 800; y++) {

 pos = y * 800 + x;

 r = red(imgOriginal.pixels[pos]);

 imgCopia.pixels[pos] = color(r, r, r);

 }

 }

 tint (#C69220);

 image(imgCopia, 0, 0);
