How to Create a Region of Interest

Main Tab

1. In the Step Name control, enter a descriptive name for the step.
2. Verify that the Reposition Region of Interest control is enabled if you want to link the region of interest specified in this step to a previously defined coordinate system.

   Link the region of interest to a coordinate system if the position of the object under inspection changes from image to image, and you need to adjust the position of the region of interest to match the new location of the object.

Note  If the Reposition Region of Interest control is enabled and any of the parameters for the region of interest are based on previous measurement results these parameters will not be updated by the coordinate system.

Coordinates Tab

3. Select the type of region of interest you want to create from the ROI Type listbox.
4. Create a region of interest in the image using the mouse or by entering values for the corresponding region of interest parameter controls. You can select to use a previous measurement or variable for the value of an region of interest parameter by selecting the measurement or variable from the drop-down list.

Note  If the value of an ROI parameter is set to a previous measurement and the step taking the measurement has Reposition Region of Interest enabled, the value of the measurement may change if the coordinate system changes.
