You can create annotation indicators in the form of straight or free-form lines, squares or rectangles, and circles or ovals.

1. Click the desired annotation tool button:
   Line  to draw a straight line, 
   Pen  to draw a free-form line, 
   Multi Shape  to draw a few free-form shapes at the same instance, 
   Rectangle  to draw a square or rectangle, or 
   Oval  to draw a circle or oval—and draw the shape on the image.

Notes:

• Press the Shift key to keep straight lines perfectly horizontal or vertical.
• Press the Shift key to create squares or circles with the Rectangle and Oval tools.
• Use the Multi Shape tool to mark a few items at the same time. When you complete drawing the shapes, click Done and type the required comments.
