First, a part of the image must be selected. Any word, area, or sequence in the image can be selected in rectangular (default) or polygonal mode. In rectangular mode, clicking the image at one corner of the area to select will draw the rectangular selection if the left mouse button is pressed. In polygonal mode, a shape can be drawn by clicking and dragging. Releasing the left mouse button places the next corner of the polygon which can be completed by double clicking. A shape which is not yet linked to a text is displayed with a dashed frame.
