Class | PImage
Name | ### copy()
Examples |
    PImage img = loadImage("tower.jpg");
    img.copy(50, 0, 50, 100, 0, 0, 50, 100);
    image(img, 0, 0);
Description | Copies a region of pixels from one image into another. If the source and destination regions aren't the same size, it will automatically resize source pixels to fit the specified target region. No alpha information is used in the process, however if the source image has an alpha channel set, it will be copied as well. The imageMode() function changes the way the parameters work. For example, a call to imageMode(CORNERS) will change the width and height parameters to define the x and y values of the opposite corner of the image.
