Class | PImage
Name | ### set()
Examples |
    PImage img = loadImage("tower.jpg");
    color black = color(0, 0, 0);
    img.set(30, 20, black);
    img.set(85, 20, black);
    img.set(85, 75, black);
    img.set(30, 75, black);
    image(img, 0, 0);
Description | Changes the color of any pixel or writes an image directly into the image. The x and y parameter specify the pixel or the upper-left corner of the image. The color parameter specifies the color value. 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". Processing requires calling loadPixels() to load the display window data into the pixels[] array before getting the values and calling updatePixels() to update the window. As of release 0149, this function ignores imageMode().
