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.

Exceptions

Exception	Condition
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.
