Double Buffering "1.1 Style"
Could someone explain to me why when I try to double buffer a generated Image it return null? Heres a code snippet:
class Can ectends Canvas
{
Image offscr;
Graphics og;
public Can()
{
offscr = createImage(500,500);
og = offscr.getGraphics();
}
public void paint(Graphics g)
{
og.drawRect(1,1,100,100);
g.drawImage(offscr,10,10,this);
}
}
This is a revised version of course, I also had some Thread work and an update method. I had this working just fine with a BufferedImage in the appletviewer but
Older browser don't support it and I don't want to make people downlod plug-ins. I have seen the exact cod listed above on-line on many pages but for some reason it just keeps returning me a null Image. I am using
jdk-1.3 and Redhat Linux 6.1.
Thanks for any comments
Ian
