	I need a routine to scale an image.  An original image is displayed
and the user selects an area to be scaled.  A rubberband box will be opened for
his selection of this area.  The new scaled image will go into a seperate 
window, which will be a constant size.  So far, I have only done scaling code
to double the image or triple the image, but I want to expand this to make the
program more useful to the average user.
	
	If anyone can give me a good algorithm or section of code to do this,
it would be very helpful.  Please send any replies to :
