Positioning the Reference and Tracker Boxes

You can position the reference and tracker boxes using the mouse, the stylus, or the numeric controls in the Timeline.

By default, when you move the reference box, the tracker box automatically moves with it. If you move or resize the tracker box, however, the reference box does not follow. Once you move or resize the tracker box, the size and position of each box remain independent of the other. You can re-establish the relationship using the Reset Tracker option.

To position the reference box using the mouse or stylus:

Click inside the reference box and drag it over the feature that you want to track.

The reference box changes to a magnifying glass to help you find a good reference point. You can adjust the magnifying mode by changing the magnification in the Tracker panel.

To position either the reference box or the tracker box using the numeric controls:

1. In the Timeline, expand the layer that contains the reference feature to display the Tracker(s), then expand the Tracker with the box(es) you want to reposition.
2. Expand the folder corresponding to the box you want to reposition.
3. Double-click X or Y, and enter the desired value(s). Or click and drag the cursor over the property's value to change the X or Y value.
