Name	background()
Examples	background(51); background(255, 204, 0); PImage img; img = loadImage("laDefense.jpg"); background(img);
Description	The background() function sets the color used for the background of the Processing window. The default background is light gray. background() is typically used within the draw() function to clear the display window at the beginning of each frame. An image can also be used as the background for a sketch, although the image's width and height must match that of the sketch window. To resize an image to the size of the sketch window, use image.resize(width, height). Images used with background() will ignore the current tint() setting. It is not possible to use transparency (alpha) with background colors on the main drawing surface; you can acheive the same effect with createGraphics().
Syntax	background(rgb) background(rgb, alpha) background(gray) background(gray, alpha) background(v1, v2, v3) background(v1, v2, v3, alpha) background(image)
Parameters	rgb int: any value of the color datatype alpha float: opacity of the background gray float: specifies a value between white and black v1 float: red or hue value (depending on the current color mode) v2 float: green or saturation value (depending on the current color mode) v3 float: blue or brightness value (depending on the current color mode) image PImage: PImage to set as background (must be same size as the sketch window)
Returns	void
