Line.SetDistanceRotation Method

Line SetDistanceRotation Method

Cognex VisionPro 9.25 SR1

Sets the X and Y properties of this line to the end of the vector (Distance, Rotation + 90 deg.) or (-Distance, Rotation - 90 deg.) for negative Distance. Sets the Rotation property to the specified Rotation.

Parameters

distance: Type: System Double
The distance from the origin to the line.

rotation: Type: System Double
The line's rotation, measured in radians from the x-axis.

Remarks

Sets the reference point and rotation of the line based on a vector. The reference point of the line is the end of the vector ( distance , rotation + 90°). If distance is negative, the reference point is the end of the vector (- distance , rotation - 90°). rotation is specified in radians and normalized to the range -π to π. You can also interpret the line as if it were parallel to the x-axis of a coordinate frame that is rotated rotation radians, and translated along the rotated y-axis by distance. In the following figure, distance is 3 and rotation is 45° (π/2 radians). And in the following figure, distance is -3 and rotation is 45° (π/2 radians).
