getGraphics();

[Bavo Bruylandt]

I wrote a whole class to produce gradients wich uses DoubleBuffering.
If I use within an applet everyting works fine, but when I stick the method
(public Image Impaint()) the getGraphics() line always delivers a NullPointerException.

Anyone an idea?

NullPointerException generally occurs when memory is not allocated to something.
Check if you have allotted memory to all those fields.

try to run once the repaint() methode and then everytime the other...I think
repaint has to run one time before the getGraphics() function is enabled
