The Polar Unwrap tool edit control provides a graphical user interface to the CogPolarUnwrapTool tool, which you use to transform the portion of an image contained within a defined region into a rectangular image. The tool produces an output image containing the transformed portion of the input region. The edit control allows you to specify a sampling mode, scaling factors, and the type of region shape to use. The following figure shows the Polar Unwrap tool edit control:

The edit control offers the following features:

• A row of control buttons at the top left provide access to the most common operations.
• A set of function tabs allow you to choose the sampling mode, the scaling factors, and the region shape.
• An image display window displays acquired images and the output image the Polar Unwrap tool generates.

You can experiment with the edit control by using QuickBuild to create a CogPolarUnwrap tool. A new CogPolarUnwrap tool appears with the input terminals for the input image and output image, as shown in the following figure:

The following table describes the function of each button:

Table 1. Control buttons

Button	Description	Function
	Run	Generate an output image of the defined region transformed into a rectangular image.
	Electric mode	Toggle electric mode, where the Polar Unwrap tool executes automatically when particular configuration parameters change. In electric mode, a lightning bolt appears next to every electric property.
	Local image display	Open or close the local image display window. A Polar Unwrap tool supports the following image buffers: The Current.InputImage buffer contains the next image the tool will analyze plus the graphic for the input region. The LastRun.InputImage buffer contains the last image processed by the Polar Unwrap tool along with any graphics you enable. The LastRun.OutputImage buffer contains the output image the tool produces.
	Floating image display	Open a floating image window, which supports the same image buffers as the local image display window.
	Open	Open 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	Save 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	Save the current properties of the vision tool to a new VisionPro persistence (.vpp) file.
	Reset	Reset the vision tool to its default state.
	Show ToolTips	Enable or disable the display of tooltips for individual items in the edit control.
	Help	Open this VisionPro online help file.
