Name | ### set()
Examples |
    color black = color(0);
    set(30, 20, black);
    set(85, 20, black);
    set(85, 75, black);
    set(30, 75, black);
    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);
      }
    }
    size(100, 100);
    PImage myImage = loadImage("apples.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 to the display window. The x and y parameters specify the pixel to change and the c parameter specifies the color value. The c parameter is interpreted according to the current color mode. (The default color mode 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.
Syntax |
    set(x, y, c)
    set(x, y, img)
Parameters |
x | int: x-coordinate of the pixel
y | int: y-coordinate of the pixel
c | int: any value of the color datatype
img | PImage: image to copy into the original image
Returns | void
