     \begin{itemize}
     \item nearest-neighbor: uses the nearest pixel value from the source
 \[
-x_{source} = x_{destination} \times scale
+x_{source} = x_{destination} \div scale
 \]
   \item bilinear interpolation: sub-pixel linear weighting of neighbor colors
   \item bicubic interpolation: smooth spline sub-pixel fitting with neighbor colors
