Let me talk about how to use background search:
1. After grabbing an image in a window, click bind window button,
and the enlarged image will change dynamically with the movement of the mouse.
At this time, you can switch other windows to block the window
and see if you can perspective the image of the window. (If not, it's bad luck
Right click anywhere to complete this binding window,
Then quickly click the Gray2Two and OK button,
the background search code can be generated.
2. The code of background search starts with the BindWindow(id),
which is equivalent to setting a state.
Subsequent searches will see this window at the top of the screen.
You can cancel this state with the BindWindow(0).
3. Once the BindWindow(id) code is generated,
subsequent capture images can be performed in a normal way,
You don't have to click the bind window button again.
