The value range of the horizontal and vertical separator bar is a virtual area with the upper left corner of 0,0 and the lower right corner of 100,100, which is given by referring to the currently displayed Scene. It is calculated in percentage. For example, the value range of the horizontal separation bar shown in the above figure is 27, 100, which represents that the area below 27% of the Scene is the area with roller shutter, and the area above 27% is the area without roller shutter. The Bounds Settings of the roller shutter can also be distinguished by the colors in the horizontal and vertical separation strips.
