Making Annotations

You can add annotations on any frozen image. To add annotations during live imaging, tap the snowflake icon to freeze the image and display the annotation tools. 

To perform a linear measurement:

1. Select the snowflake to freeze the image.
2. Select the Annotation button, which has "Aa" and a line.
3. Select the line symbol.
4. Select the blue circles to drag the yellow cross-hairs to the start and end positions of your measurement. As you manipulate the ends of the line, the length (in centimeters) is displayed in a box at the bottom of the image. You can drag this box to the desired location on the image.
5. To add another line, select the Annotation button and select the line symbol again. The next line is displayed in a different color and has a letter next to it. You can add up to four linear measurements to each image.
6. To delete a line, select the line or the line's measurement. Select the X next to the corresponding numeric measurement display, and select Delete Line to confirm.
