Scaling about a Reference Point:-

If the center of the object is not at the origin, in this case we should consider a scaling as a composite transformation which involves the following steps.

  1. Translation of the reference (xc,yc) to the origin
  2. Scale the object by scale factor by (Sx,Sy)
  3. Translation …
