Description | The background() function sets the color used for the background of the Processing window. The default background is light gray. In the draw() function, the background color is used to clear the display window at the beginning of each frame.
An image can also be used as the background for a sketch, however its width and height must be the same size as the sketch window. To resize an image 'b' to the size of the sketch window, use b.resize(width, height). Images used as background will ignore the current tint() setting. It is not possible to use transparency (alpha) in background colors with the main drawing surface, however they will work properly with createGraphics. |
