Magnifying a shrunken image --- without using imageData

[Roger.E.Eller at sealedair.com]

I have an image that is larger than the screenRect. I scale it to fit the 
window. Now I want to magnify a portion (100x100 pixels) in another image 
object.

The problem is that if I put the text of (a portion of the imageData) into 
the magnified image, it is VERY pixelized. I need to access the original 
full resolution image for the magnified area.

How can I accomplish this without using an external? Thanks for any 
suggestions.
