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, 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 (the placement of the image is not affected by the imageMode() function).
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". The (BETA) version of 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.

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
