Dilation with Dilation center as non-origin
Dilation with Dilation center as origin
Scale factor: SF
Pre-Image Point: (xp, yp)
Image Point: (xim, yim)
Center of dilation: (xc, yc)
Dilation Rule: Image coordinates =( Pre-image )(Scale factor) – (center of dilation)
Dilation Rule: xim = (xp)(SF) - xc
and
yim = (yp)(SF) - yc
