This parameter is expressed as a number of video lines.

Positive values shift the grabbing window in the downward direction. The resulting displayed image is shifted in the upward direction.

Negative values shift the grabbing window in the upward direction. The resulting displayed image is shifted in the downward direction.

The "get" value exactly reflects the shifted amount. For internal hardware reasons, it may slightly differ from the "set" value established by the user.

The parameter OffsetY_Ln is usable when the camera feeding the channel is an analog or digital area-scan camera. It is meaningless for line-scan cameras.

Parameters setting

The parameters must be set in the following order:

  1. The GrabWindow parameter is set to MAN.
  2. The WindowX_Px and the WindowY_Ln parameters are defined.
  3. The OffsetX_Px and the OffsetY_Ln parameters are defined.
