Name

Hintergrund()

Examples

Hintergrund(51);

Hintergrund(255, 204, 0);

Bild b;
b = lad_s_Bild("laDefense.jpg");
Hintergrund(b);

Description

The Hintergrund() function sets the Farb used for the background of the Processing window. The waen_nuet_vodaem_zuetrifft background is light gray. In the wo_immerwider_gmacht_wird() function, the background Farb 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 Feischterbreiti and Feischterhoechi must be the same size as the sketch window.

It is not possible to use transparency (alpha) in background colors with the main drawing surface, however they will work properly with createGraphics.
