Figure 5.14 Pick and Place Points for a Circular Window
•
A
B
Anywhere on the
circumference
Note that pick and place points are located anywhere on the circumference of
the window and at the center of the window. These pick and place points
have the following functions:
•
Center of window –– The center pick and place point enables you to
move the entire window anywhere within the image field without
changing the window’s size.
•
Circumference –– The entire circumference is a pick and place point for
the purpose of changing the window’s size or radius.
Figure 5.15 (page 5–16) demonstrates the operation of the circular window
pick and place points in two steps, as follows:
•
Step 1: The window is picked at point B, dragged to point B
′, and then
placed at point B
′. This increases the radius of the circle.
•
Step 2: The window is picked at the center point A, the entire window is
dragged to point A
′, and it is then placed (unaltered) at point A′.
