8 Control commands for Panning, Tilting, Zooming and Focusing
"ptzf" command is used for controlling Pan, Tilt, Zoom and Focus. The followings explain "relative"
parameter, "AbsolutePanTilt" parameter and "AreaZoom" parameter. "relative" parameter is used for the
relative displacement. "AreaZoom" parameter is used in the case the selected rectangle area of the host
image is required to zoom. "ContinuousPanTiltZoom" parameter is for Joystick operation.

8.1 relative parameter (syntax: relative=aabb)
It is possible to make the relative displacement of the Pan, Tilt and Zoom by using the relative parameter.
The difference between this parameter and "visca" parameter of relative position assignment is the
presence of normalization with its Zoom position.
How to set the value "aa"
The value "aa" stands for the controlled item and direction such as "Pan position to the right" of "Zoom
position to WIDE". It is possible to set the value "aa" by the following Figure or explanation below.

How to set the value of "bb"
The value of "bb" stands for the degree of displacement whose range is from 01 to 10. The displacement
is based on the current video size. The degree of Pan and Zoom displacement is shown in Table 9.1-1 :
Pan/Tilt distance.

Value Distance: Percent of the current video size.
01 around 10%
02 around 15%
