UI Line Tool 
The UI Line Tool allows you to insert text right onto the image and
move it around, rather than having to type into a text box. Click
on the UI Line Tool and drag 'n' drop it onto the image viewer. Start
typing in the rectangle. You can move the entire rectangle by
picking on one of the solid lines. As you drag the smaller boxes
along the rectangle defining your text, the rectangle and font size
change accordingly.

Right-click
on the UI line area rectangle to bring up the UILineEntity edit box, as
seen below. Selecting
the Render Style
tab allows you to adjust the colors, font, style and appearance of
the text. Make the necessary
adjustments and click Close. The values will be updated
according to
your selections.

Selecting the Rectangle
tab allows you to enter specific
values for the UI line entity rectangle used, including center X, Y,
width, height and aspect of width/height. After entering your
values, click Apply and then Close. The UI line entity will be adjusted
according to the selections.

Selecting
the Entity
tab allows you to adjust the colors, thickness and
visibility of the UI line profile marker. You can also select a
Coordinate System. Make the necessary adjustments click
Apply and then Close. The values will be updated according
to
your selections.
