Fast screen drawing from memory bitmap source

Question

Hello
I have got pixels (frames) coming out from frame grabber that I wanted to display so that I could get higher framerates than using standard method (about 5 fps):
i = createImage(new MemoryImageSource(width, height, pixels, 0, width));
g.drawImage(i,0,0,width,height,null);
Anyone knows a faster way to display memory bitmaps in Java?
cheers

Paul,
Here is hopefully a simple example of how to save some cpu time when drawing images. We will create a buffered image that is compatible with the screen and draw the original image on it.
BufferedImage imageToDrawOn; //going to be created
BufferedImage original; //allready loaded (use java.IO.read() )
imageToDrawOn = gc.createCompatibleImage(original.getWidth(),original.getHeight(),Transparency.BITMASK);
imageToDrawOn.getGraphics().drawImage(original,0,0, null);
//code
//example of how to display the image:
g.drawImage(imageToDrawOn, 0, 0, this);
I hope this helps!
