perform measurements. You can:
• Measure distances.
• Calibrate distances.
• Measure angles.
• Calculate the scan average level within a region of interest (ROI).
• Calculate density profiles.
• Draw lines.
• Draw arrows.
• Draw geometric forms (rectangles, ellipses, polygons).
• Add custom texts and predefined texts.
As an aid when performing measurements or calculations or when adding
annotations, you can display grid lines on the image.
Annotations can be shown or hidden.
v
You can access the above annotation functions via the buttons on the

ANNOTATION SOFTWARE
Adding an annotation
The ADC Annotation Software permits adding the following annotations to
images: lines, arrows, geometric forms (rectangles, circles, and polygons),
predefined text, and custom text. Additionally, distance and angle
measurements can be performed. Distance and angle measurements can be
calibrated if the image includes a calibrated object. Images can be viewed
with annotations turned on or off.
Furthermore, the scan average level and the histogram can be determined for
regions of interest and density profiles along lines can be displayed.
Showing/hiding annotations
If annotations have been added to an image, you can choose to show or hide
the annotations.
v
Turn on annotations before adding annotations or performing
measurements or calculations.
v
If you turn off annotations and save the result, the annotations are not
lost. At any time, you can turn annotations on again.
To turn annotations on or off:
On the View menu, click Annotations.
A check mark means that annotations are turned on. If the image has annotations,
the image with its annotations is displayed in the image pan e .

Measuring a distance
Via the Annotation toolbar, you can measure the distance between specific
features in an image. If you have not calibrated the distance measurement
using a reference object in the image, the measurement is referenced against
the image plate dimensions.

If you wish to use calibrated distance meas urements, calibrate first. Refer
to ’Calibrating distance measurements’ on page 15.
To measure one or more distances:
