set()
Examples
example pic
color black = color(0);
set(30, 20, black);
set(85, 20, black);
set(85, 75, black);
set(30, 75, black);
example pic
for (int i = 30; i < width-15; i++) {
  for(int j = 20; j < height-25; j++) {
    color c = color(204-j, 153-i, 0);
    set(i, j, c);
  }
}
example pic
size(100, 100, P3D);
PImage myImage = loadImage("topanga.jpg");
set(0, 0, myImage);
line(0, 0, width, height);
line(0, height, width, 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 (with imageMode(CORNER) or CORNERS), and the center of the image with imageMode(CENTER).

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". You must call loadPixels() to load the display window data into the pixels[] array before setting the values and calling updatePixels() to update the window with any changes.
Syntax 
set(x, y, color)
set(x, y, image)
Parameters
x int: x-coordinate of the pixel
y int: y-coordinate of the pixel
color color: any value of the color datatype
image PImage: any valid variable of type PImage
