It allows you to obtain a rectangle from the frame, whose dimensions are fully adjustable by four sliders for the four sides of the frame. You can also place this rectangle in the canvas using two other sliders for right/left and up/down scrolling. With the Clear buttons we can bring the slider to default values without affecting the other parameters. Unlike the Crop tool, the original frame size is not altered and being keyframable allows a wide variety of uses. In figure 10.36 the Crop & Position plugin is compared with the Crop tool.
