Click the "Load Master" button to load a master image.

 Once the master is loaded, a red polygon appears. Select the polygon by moving the cursor over the polygon and clicking.

 The individual points can be moved by placing the cursor over a point and dragging the point.

The polygon can be rotated by SHIFT-CLICKING a point and dragging the mouse.

Move and resize the red polygon over the destination image to specify where the slave will be transferred. If the image is large, click the "View Normal Size" radio button to see the entire image. Once you have the polygon in the approximate location, click the "Zoom In" button to accurately move the polygon points.
