-S x y
    Specifies the exact screen dimension of the output GIF.

-s scale
    Set scaling factor for both x & y direction to Scale. Default is 0.5. Note this is a floating point number.

-x xscale
    Set scaling factor for x direction to Scale. Default is 0.5. Note: this is a floating point number.

-y yscale
