Fit Circle Tool

The Fit Circle edit control provides a graphical user interface to the FitCircleTool, which takes a set of input points and returns the circle that best fits those input points while generating the smallest root mean square (RMSError) error. A Fit Circle tool requires a minimum of three input points.

The following figure shows an example Fit Circle edit control: 

See the topic Control Reference for a description of the buttons along the top of the edit control. The Fit Circle tool edit control supports the following image buffers:
