Method Description
ComputeOrientationLine ( RectangleF rect, float angle, PointF &start, PointF &end ) : void
CreateGeometricTransform ( RectangleF rect, Point points ) : CGAffineTransform

This method initializes the new CGAffineTransform such that it represents the geometric transform that maps the rectangle specified by the rect parameter to the parallelogram defined by the three points in the plgpts parameter. The upper-left corner of the rectangle is mapped to the first point in the plgpts array, the upper-right corner is mapped to the second point, and the lower-left corner is mapped to the third point. The lower-right point of the parallelogram is implied by the first three.
