CogRectangleAffine SetOriginLengthsRotationSkew Method Cognex VisionPro 9.24
Initialize this affine rectangle from its origin point, SideXLength, SideYLength, Rotation and Skew. All angles are in radians.

Namespace: Cognex.VisionPro

Syntax

public void SetOriginLengthsRotationSkew(
	double originX,
	double originY,
	double sideXLength,
	double sideYLength,
	double rotation,
	double skew
)

Parameters

originX
Type: System Double

The x-coordinate of the origin point (Po).

originY
Type: System Double

The y-coordinate of the origin point (Po).

sideXLength
Type: System Double

The length of side x (the side along the x-axis).

sideYLength
Type: System Double

The length of side y (the side along the y-axis).

rotation
Type: System Double

The rotation angle in radians.

skew
Type: System Double

The skew angle in radians.

    ExceptionCondition
    ArgumentException

    sideXLength is <= 0 or sideYLength is <= 0.

    Remarks

    Sets this affine rectangle from the specified origin point (Po), side x length, side y length, rotation angle, and skew angle as shown in the following illustration:

    Note: To prevent degenerate affine rectangles, setting skew to within +/- 0.002 of +/-(π/2) causes the value to be set to either (-π/2 - 0.002) or (π/2 + 0.002) for negative and positive values of skew, respectively.
