DclSetAspectRatio

(X, [y])

X	< R >	The length of the x direction of a frame. The unit is optional.
Y	< R >	The length of the y direction of a frame. The unit is optional. It is 1 at the time of omission.

Because the ratio of the length and breadth of only the frame becomes a problem the unit is optional and good.
It shall be X, Y > 0.
