由整数类型的 x、y、宽度、高度定义的 2D 矩形。
| allPositionsWithin | 包含 RectInt 中所有位置的 RectInt.PositionCollection。 | 
| center | 矩形的中心坐标。 | 
| height | 矩形的高度。 | 
| max | The upper right corner of the rectangle; which is the maximal position of the rectangle along the x- and y-axes, when it is aligned to both axes. | 
| min | The lower left corner of the rectangle; which is the minimal position of the rectangle along the x- and y-axes, when it is aligned to both axes. | 
| position | 返回 RectInt 的位置 (x, y)。 | 
| size | 返回 RectInt 的宽度和高度。 | 
| width | 矩形的宽度。 | 
| x | 矩形的左坐标。 | 
| xMax | Shows the maximum X value of the RectInt. | 
| xMin | Shows the minimum X value of the RectInt. | 
| y | 矩形的上坐标。 | 
| yMax | Shows the maximum Y value of the RectInt. | 
| yMin | Show the minimum Y value of the RectInt. |
