ROI 工具的应用顺序
生成的 ROI 区域由各个 ROI 工具的加法或减法区域组成。应用顺序与加法顺序完全一致。
如果摄像机上已经配置了 ROI（请参阅摄像机 ROI），则该 ROI 始终是第一个 ROI。因此可以通过添加或删除新区域来编辑摄像机上的现有 ROI。这既适用于 "模型 ROI"，也适用于 "执行 ROI"。
编辑图形时，所选的绘图工具会显示在前面（另请参阅选择ROI 绘图工具）。点击绘图工具旁边的图像，显示的顺序会自动重置为实际应用的顺序。
使用加法和减法 ROI 工具生成 ROI 的示例
Order of application for ROI tools
The resulting ROI area consists of the additive or subtractive areas of the individual ROI tools. The order of application corresponds exactly to the order of addition.
If an ROI is already configured on the camera (see Camera ROI), this is always the first ROI. An existing ROI on the camera can thus be edited by adding or removing new areas. This applies to "Model ROI" as well as Execution ROI.
While editing the shapes, selected drawing tools are brought to the front (see also Selecting an ROI drawing tool). The displayed order is automatically reset to the actually applied order by clicking on the image next to the drawing tools.
