Pick and Place Function
5–23
Figure 5.21 shows how a polygon window appear in the default state after
you select the pick and place function. It also shows the pick and place points
that apply when a polygon window is in the Move Vertex mode, the default
mode. (The other modes are Move Polygon, Add Vertex, and Delete Vertex.)
NOTE: In the Move Polygon mode, you can pick the polygon from any
point in the image field and drag the entire polygon, unaltered, anywhere
around the image field.

The Move Vertex pick and place points are located at each vertex on the
window (A, B, C, and D), as shown in Figure 5.20. These pick and place
points enable you to drag a vertex anywhere within the image field. There are
no restrictions on its movement; thus, for example, you can drag a vertex
across one of the polygon’s sides.
Figure 5.22 (page 5–24) demonstrates the operation of the Move Vertex pick
place points in the following steps.
•
Step 1: The vertex is picked at point A, dragged to point A
′, and then
placed at point A
′. This increases the width of the polygon.
•
Step 2: The vertex is picked at point D, dragged through the bottom side
to point D
′, and then placed at point D′. This has the effect of creating two
three–sided polygons, joined at a vertex.
