DrawImage() public method

Draws the specified Image at the specified location and with the specified shape and size. The destPoints parameter specifies three points of a parallelogram. The three Point structures represent the upper-left, upper-right, and lower-left corners of the parallelogram. The fourth point is extrapolated from the first three to form a parallelogram. The image represented by the image parameter is scaled and sheared to fit the shape of the parallelogram specified by the destPoints parameters.

public DrawImage ( Image image, Point destPoints ) : void
image	Image	Image.
destPoints	Point	Destination points.
return	void

            if (destPoints == null)

            if (destPoints.Length < 3)
                throw new ArgumentException ("Destination points must be an array with a length of 3 or 4. " +
                    "A length of 3 defines a parallelogram with the upper-left, upper-right, " +
                    "and lower-left corners. A length of 4 defines a quadrilateral with the " +
                    "fourth element of the array specifying the lower-right coordinate.");

            // Windows throws a Not Implemented error if the points are more than 3
