AFAIK interpolation mode is the only thing that affects the quality of
scaled images.
Try save in png or windows bitmap as the JPEG encoder may be affecting the
quaility.

My guess is that you are tring to match something done in a professional
package like Adobe and you may not get the same results with standard GDI+.
