Parameter Description

This integer parameter reflects the vertical position offset of the center of the Window Area relative to the center of the camera active area.

The "get" value exactly reflects the shifted amount. It may differ from the "set" value established by the user since MultiCam automatically corrects invalid values.

Parameter Usage

Relevance condition(s):
  • Condition: Manually defined grabbing window area (GrabWindow=MAN)
  • Condition: Area-scan camera (Imaging = AREA) having a single region along the Y direction (TapGeometry ≠ *_2YE)
Prerequisite action(s):
  • Condition: Grabbing window definition method already selected through GrabWindow
  • Condition: Grabbing window height already set through WindowY_Ln

Directive: Assigning a value of zero means that the grabbing window area is vertically centered on the Camera Active Area. Increasing the value shifts the grabbing window area in the downward direction. Decreasing the value shifts the grabbing window area in the upward direction.

Directive: The grabbing window area must be included entirely within the camera active area.

Parameter Values

Numeric values: , , 0

Table 1. Minimum Range
 

Description

The grabbing window is at the uppermost position within the camera active area. The lower limit of the range is context dependent. The lowest value is equal to [- (Vactive_Ln - WindowY_Ln) / 2].

Always applicable.

Table 2. Maximum Range
 

Description

The grabbing window is at the lowermost position within the camera active area. The upper limit of the range is context dependent. The upper value is equal to [(Vactive_Ln - WindowY_Ln + 1) / 2].

Always applicable.
