Valid coordinate values for a rectangle are in the range –32,768 through 32,767. Valid widths and heights, which must be positive, are in the range 0 through 32,767. This means that a rectangle whose left and right sides or whose top and bottom are further apart than 32,768 units is not valid. Following is a rectangle whose upper-left corner is left of the origin and whose width is less than 32,767.
