The Angle Point Point edit control provides a graphical user interface to the AnglePointPoint method, which measures the angle of the line segment defined between the two points (StartX, StartY) and (EndX, EndY). The edit control allows you to specify the two points, dictate which graphics appear as the tool executes, and view tool results. The following figure shows the Angle Point Point edit control:

The edit control offers the following features:
- A row of control buttons at the top left
- A set of function tabs to specify the two points, choose what graphics the tool will use, and view the angle result
- An image display window for displaying tool images and graphics
You can experiment with the edit control by using QuickBuild to create a CogAnglePointPointTool tool. A new CogAnglePointPointTool tool appears as shown in the following figure:

To include the edit control in your custom vision application, you must first add it to your Visual Studio.NET development environment. See Using Edit Controls in Your Custom Vision Applications for more information.

The following table describes the function of each button:
| Button | Description | Function |
![]() | Run | Measures the angle between the two points |
![]() | Electric mode | Toggles electric mode, where the Angle Point Point tool executes automatically when particular configuration parameters change. In electric mode, a lightning bolt appears next to every electric property |
![]() | Local image display | Opens or closes the local image display window. An Angle Point Point tool supports the following image buffers:
|
![]() | Floating image display | Opens one or more floating image windows, which support the same image buffers as the local image display window |
![]() | Open | Opens a VisionPro persistence (.vpp) file that contains a set of saved properties for this vision tool object type. VisionPro reports an error if you try to open a .vpp file for another object type. |
![]() | Save | Saves the current properties of the vision tool to a VisionPro persistence (.vpp) file. The edit control allows you to choose between saving the vision tool with or without its image buffers and tool results. |
![]() | Save As | Saves the current properties of the vision tool to a new VisionPro persistence (.vpp) file |
![]() | Reset | Resets the vision tool to its default state. |
![]() | Show ToolTips | Enables or disables the display of tooltips for individual items in the edit control |
![]() | Help | Opens this VisionPro online help file |
Use the Settings tab to Use the Settings tab to define StartX, StartY, Endx and EndY. The following figure shows the Settings tab:

The Settings tab offers the following features:
| Feature | Description |
| StartX and StartY | The (x, y) coordinate of the first point |
| EndX and EndY | The (x, y) coordinate of the second point |
Use the Graphics tab to control which graphics the Angle Point Point tool generates and displays. The following figure shows the Graphics tab:

The Graphics tab offers the following features:
| Feature | Description |
| Show Input Image | Determines whether or not the input image is recorded as part of the diagnostic record, and whether the image is copied to the record or saved in the record as a reference |
| Show Start Point | Display the point defined by the parameters StartX and StartY in the LastRun.InputImage buffer |
| Show End Point | Display the point defined by the parameters EndX and EndY in the LastRun.InputImage buffer |
| Show Arrow | Show the arrow defining the line segment between (StartX, StartY) and (EndX, EndY) |
Use the Results tab to view the angle of the line segment between (StartX, StartY) and (EndX, EndY). The following figure shows the Results tab:

The Results tab has only one feature:
| Feature | Description |
| Angle | The angle between the two points |
