The Create Line Parallel edit control provides a graphical user interface to the CreateLineParallel method, which creates a new line that is parallel to Line on the point (X, Y). The edit control allows you to configure the line and the point, dictate which graphics appear as the tool executes, and view tool results. The following figure shows the Create Line Parallel edit control:

The edit control offers the following features:

• A row of control buttons at the top left
• A set of function tabs to define the line and the point, choose what graphics the tool will use, and view results
• An image display window for displaying tool images and graphics

You can experiment with the edit control by using QuickBuild to create a CogCreateLineParallel tool. A new CogCreateLineParallel 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:

Table 1. Control buttons

Button	Description	Function
	Run	Creates a new line on the input point parallel to the input line
	Electric mode	Toggles electric mode, where the Create Line Parallel 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. A Create Line Parallel tool supports the following image buffers: The Current.InputImage buffer contains the current image and the input point and input line The LastRun.InputImage buffer contains the results of the tool after it creates a parallel line on the input point
	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
