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.



color black = color(0);
set(30, 20, black);
set(85, 20, black);
set(85, 75, black);
set(30, 75, black);
