An offscreen graphics-context object is mainly used to create bit maps or pdf contents.

For example, if you create an offscreen graphics-context for a bit map and draw to it, you will create a bit map, from which you can create and image which you can then draw to another destination such as a screen graphics context. (This is very useful for improving performance, when doing animations.)
