Correct scaling factor for Window to Viewport transformation are :

(a)	$s_{x} = \frac{x_{v m a x} + x_{v m i n}}{x_{w m a x} + x_{w m i n}}, s_{y} = \frac{y_{v m a x} + y_{v m i n}}{y_{w m a x} + y_{w m i n}}$
(b)	$s_{x} = \frac{x_{v m a x} + x_{v m i n}}{x_{w m a x} - x_{w m i n}}, s_{y} = \frac{y_{v m a x} + y_{v m i n}}{y_{w m a x} - y_{w m i n}}$
(c)	$s_{x} = \frac{x_{v m a x} - x_{v m i n}}{x_{w m a x} - x_{w m i n}}, s_{y} = \frac{y_{v m a x} - y_{v m i n}}{y_{w m a x} - y_{w m i n}}$
(d)	$s_{x} = \frac{x_{v m a x} - x_{v m i n}}{x_{w m a x} + x_{w m i n}}, s_{y} = \frac{y_{v m a x} - y_{v m i n}}{y_{w m a x} + y_{w m i n}}$
