Lens

The call script is :-

vfx.Lens(clip [,int sf = 0][,int ef = end frame][, int rad = smaller dimension / 8 ][,float mag = 4.0][, int drop = 1 ][, int x = width / 2][,int y = height / 2][, int erad = rad] [, float emag = mag][, int ex = x][, int ey = y])

clip: input clip of constant format. Compat input not accepted.
sf: Effect start Frame Number
ef: Effect End Frame Number
rad: radius of circular lens. 4 to 1/2 of frame smaller dimension.
mag: magnification. 1.5 to 8.0.
drop: if set 0 uniform otherwise decreses from center to edges of discs.
x: x coord of lens center. In frame.
y: y coord of lens center. In frame.
erad: radius at end. 4 to 1/2 of frame smaller dimension.
emag: magnification at end. 1.5 to 8.0.
ex: ex coord of lens center. In frame.
ey: ey coord of lens center. In frame.

This function creates circular magnifying Lens. The parameters rad, mag, x and y will be linearly changed to erad, emag, ex, and ey by the end of effect. .
