CSize ScaleWindowExt( int xNum, int xDenom, int yNum, int yDenom );
xNum
Specifies the amount by which to multiply the current x-extent.
xDenom
Specifies the amount by which to divide the current x-extent.
yNum
Specifies the amount by which to multiply the current y-extent.
yDenom
Specifies the amount by which to divide the current y-extent.
Modifies the window extents relative to the current values. The formulas are written as follows:
xNewVE = ( xOldVE * xNum ) / xDenom
yNewVE = ( yOldVE * yNum ) / yDenom
The new extent is calculated by multiplying the current extents by the given numerator and then dividing by the given denominator.
The previous window extents (in logical units) as a CSize object.
