CogLine.SetFromStartXYEndXY Method

CogLine SetFromStartXYEndXY Method

Cognex VisionPro 9.7

Sets the line parameters from a pair of X and Y coordinates that are unique points on the line. The first coordinate pair will be used as the reference point on the line. The direction of the line is from the first point to the second.

Parameters

x0: Type: System Double
The x-coordinate of the first point. This is the x-coordinate of the line's reference point.

y0: Type: System Double
The y-coordinate of the first point. This is the y-coordinate of the line's reference point.

x1: Type: System Double
The x-coordinate of the second point.

y1: Type: System Double
The y-coordinate of the second point.

Exceptions

CogShapeCoordinatesMustDifferException	The points specified are not unique

Remarks

Sets the line properties from a pair of x-, y-coordinates that are unique points on the line. The first coordinate pair is the reference point of the line. The direction of the line is from the first point to the second.
