Hi all...

I feel like I'm missing something very simple here. I'm creating a simple image of random colored pixels and want the red value of each pixel to increase step by step. For the life of me I can't figure out why I'm not seeing the image change tint. What am I missing? Here's the code...


PImage img;

void setup()
{
  frameRate(5);
  size(200, 200); 
  img = createImage(100, 100, RGB);
  for(int i=0; i < img.pixels.length; i++) {
    img.pixels[i] = color(random(0,255),random(0,255), random(0,255));
  }
}

void draw()
{
  background(204);
  for (int i = 0; i < img.pixels.length; i++) {

    float r = red(img.pixels[i]);
    float g = green(img.pixels[i]);
    float b = blue(img.pixels[i]);


    if (r < 254.0) {
      r = r + 1.0;
    }
    color c;
    c = color(r,g,b);
    img.pixels[i] = c;
  }
  image(img, 50, 50);
  println(frameCount);
}
