What I'd do in your place would be to use a TBitmap of the required size 
and populate it with whatever image you need. You're just working in 
memory, no visual components implied, you shouldn't have any constraint 
in its size. Then you may copy to the canvas of the visual object just 
the portion you want to show.
It should work quite smoothly.
