Converting a BufferedImage to an Image

Question

I have a program with some BufferedImages that the user needs to be able to drag around the screen.
1) The dragging process is very sluggish when I use BufferedImages, but not when I use normal Images. Is this normal, or is something wrong with my program?
2) If using Images is the only way to fix this problem, how do I draw my BufferedImages into Images or convert them to Images? They have to start out as BufferedImages so that they can undergo a one-time rescaling operation.

Answer 1

Where can I find out what a profiler is and how to use one?
Here is an abbreviated version of the code. A non-buffered Image is available for dragging here, and it too drags sluggishly unless you eliminate the line of code that draws the BufferedImages to the screen. There is probably something else wrong with this program, because at one point dragging the BufferedImages did work well. When the problem appeared I tore my code apart trying to find out what I had messed up, but after reversing all the recent changes I had not eliminated the problem and was left mystified.
