Input Points
Use the Input Points grid of the Settings tab to specify the number and (x,y) coordinates of the input points for this Fit Circle tool, which requires a minimum of three. Use the function buttons, shown in the following figure, to add, delete and reorder the input points:
| Button | Description |
|---|---|
|
Add a new input point. Initially, the input point has the coordinates (0, 0), and you must reference a valid point result generated by another vision tool. With QuickBuild you can connect the output (x, y) terminals of a valid point to the input (x, y) terminals of a Fit Ellipse point. In your custom vision application you use the SetPoint method. |
|
Delete the currently highlighted input point from the list. If you have fewer than three input points plus the number of points to ignore, the edit control displays the message Not Enough Input Points and the Fit Circle tool will not function properly. |
|
Move the highlighted input point up one position in the list, although the order of input points does not affect the operation of the Fit Ellipse tool. |
|
Move the highlighted input point down one position in the list, although the order of input points does not affect the operation of the Fit Ellipse tool. |
