0.01 degree.
zoom
Specify the image size in one of the following formats:

Tip
As for pan, tilt and zoom, a relative position from the current position can be specified using
"d" indicating the current position.
Example:
Pan 10 degrees to the right from the current position
Tilt 5 degrees downward from the current position
Narrow the viewing angle by 2 degrees
Widen the viewing angle by 2 degrees
Also, a ratio of the current viewing angle can be specified using "v." In this specification
method, set a ratio based on the current viewing angle being 100. (One half the viewing angle
corresponds to 50, while twice the viewing angle corresponds to 200.)
Example:
Pan to the right by the viewing angle (= 1 screen) from the current position
Tilt downward by one half the screen from the current position
Halve the viewing angle
Double the viewing angle
Example:Viewing angle of 50 degrees
Viewing angle of 5 degrees
