You did not tell us what you want to achieve. So the following should 
give you what you asked for, but it might not be what you really want:

	BufferedImage argb = ...

	BufferedImage bb = new BufferedImage(
				argb.getWidth(),
				argb.getHeight(),
				TYPE_BYTE_BINARY);
	Graphics2D g = bb.createGraphics();
	bb.drawImage(argb, 0, 0, null);

Note: Not using an image observer can get you in trouble, e.g. if argb 
is not completely loaded when you try to draw it on bb. But you get the 
idea.
