Class | PImage
Name | ### set()
Examples |
    PImage tower;

    void setup() {
      size(100, 100);
      tower = loadImage("tower.jpg");
      color black = color(0);
      tower.set(30, 20, black);
      tower.set(85, 20, black);
      tower.set(85, 75, black);
      tower.set(30, 75, black);
    }

    void draw() {
      image(tower, 0, 0);
    }
Description | Changes the color of any pixel or writes an image directly into the display window. The x and y parameters specify the pixel to change and the color parameter specifies the color value. The color parameter is affected by the current color mode (the default is RGB values from 0 to 255). When setting an image, the x and y parameters define the coordinates for the upper-left corner of the image, regardless of the current imageMode(). Setting the color of a single pixel with set(x, y) is easy, but not as fast as putting the data directly into pixels[]. The equivalent statement to set(x, y, #000000) using pixels[] is pixels[y*width+x] = #000000. See the reference for pixels[] for more information.

x | int: x-coordinate of the pixel
