Return valueFurther information
The function returns the four corners aCorners of the rotated rectangle as TcVnArray4_Point2_REAL, which corresponds to an Array [0..3] of TcVnPoint2_REAL . At an angle of 0°, aCorners[0] contains the coordinates of the lower left corner of the rectangle parallel to the axes. The remaining indices follow a clockwise order from the top left (aCorners[1]), top right (aCorners[2]), to the bottom right (aCorners[3]). If the rectangle is rotated by 165°, for example, the corner assignment rotates accordingly so that the original bottom left corner is now at the top right.
