Measurement and Annotation Functions
The Processing page / Measurement / Annotation functions give
the user many capabilities to measure distances, angles, diameters
and areas as well as locating and labelling items that are of significant
interest on the sample area.
TOOLS
Selected measurement or annotation tool is displayed as the tool icon.
Clicking the icon activates / deactivates the tool (the active one is
highlighted). Clicking the arrow next the icon symbol opens the list of
available tools to choose. The appropriate icon is shown from that
time on and the item can be drawn on screen. The drawn items are
listed in the list box.
• The Measurements enable to gain dimension information about a
specimen feature by overlaying it with a measurement graphic. By
changing the magnification these graphic elements resize
accordingly.
• The Annotations enable to graphically label items of interest.
• The Text enables to add further information.
• The Trash can button deletes selected item(s).
The Property Editor
enables to change a property of a selected Measurement / Annotation
/ Text graphic by a selection from the drop down list or by a direct
editing of a text or a value.

from the point where you have clicked as from the centre.
3. Choose the Text symbol and then just click where you require a
text in the image. Type the text into the Property editor text field.
Click the text or press the enter key to confirm it and the text
appears onscreen.
