P = CPoint:Offset( dx )

P = CPoint:Offset( dx, dy )

P = CPoint:Offset( CPoint_old )

P = CPoint:Offset( CRect_old )

P = CPoint:Offset( tblOffset )

    dx is the offset to apply to both the x and y members of the CPoint.

    dx and dy are offset values to apply respectively to the x and y members of the CPoint.

    CPoint_old is another CPoint object. Its x and y members are used as offsets to the x and y members of the current CPoint.

    CRect_old is a CRect object. Its Width and Height are used respectively as offsets for the x and y members of the CPoint.

    tblOffset is a 1-dimensional array. Element 1 is used to offset the x member and element 2 is used to offset the y member of the CPoint.

    P returned is the original CPoint object. This allows the Offset method to be used as part of an operator expression, if desired.

    On failure, nil is returned.

P = new_point(4.4,-12.7)

-- create a CPoint object

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=4.4, y=-12.7

P:Offset( -4, 6 )

-- offset the values

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=0.4, y=-6.7

P:Offset( new_rect(1,2,5,8) )

-- create a rectable offset in the method call

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=1.4, y=-3.7 (apply width and height)
