13. Step 5, Overlay Alignment. For this step, you’ll find it helpful to have a very large video
image, so resize the TeachTarget window to make the video image as large as possible.
TeachTarget adds two concentric red overlay rings to the captured image of the target (see
Figure 4.6 ). If you identified a secondary target in the previous step, TeachTarget adds the
red rings to the secondary target, as shown in Figure 4.7 on page 4.8 .
14. If the rings aren’t centered on the target, use the Ring position buttons to center them.
15. Use the GROW and SHRINK buttons to adjust the size of the rings until they just
enclose the edge of the target feature (see Figure 4.6 ). For a secondary, ring-shaped target,
choose either the target’s inner edge or outer edge to enclose with the red rings (see
Figure 4.7 on page 4.8 ).
