Attach a note to a Line markup
Attach a note to nearly any markup that does not have a text box of its own by double-clicking the markup to open the Note pop-up window. Notes attached to markups are functionally similar to the Note Tool.
Add an action to a Line markup
You can add an action to almost any markup. Right-click the markup and select Edit Action.
Icon indicators in markups
Markups may display indicator icons below and to the right of the markup (or grouped markups). These include:
Action: Shows that an action is defined for this markup. Select to trigger the action.
Capture: Shows that the markup has embedded media (typically an image or video). Select this icon to open a preview window.
Reply: Shows one or more replies exist in the Markups list. Hover to preview replies or select to jump to the markup's entry. Turn off the ability to see reply indicators in the View menu.
Resize or Adjust a Line markup
Select a markup to reveal its control handles. Each handle controls a different aspect of size and orientation.
Resize the markup or change its angle: Drag the appropriate yellow handle. Hold Shift while dragging to force the markup to a horizontal, vertical, or 45° angle.
See Editing Markups for more information.
Changing a Line markup appearance
The appearance of the Line markup is configurable, including its color, thickness, pattern, ends, and opacity.
To change the appearance of a Line markup, select the markup and select the Properties panel. Go to Window > Panels > Properties to show the Properties panel if it is hidden. Several properties will also be available on the Properties toolbar when the markup is selected.
Appearance properties
Color: Sets the line color.
Fill Color: Controls the fill color of the endpoints.
Highlight: Makes the fill color and line transparent so underlying content shows through.
Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).
Line Width: Sets the line thickness in points. A setting of 0 effectively renders the line invisible.
Style: Determines the line pattern. In addition, there are several advanced line styles and you can create Custom Line Styles.
Start and End: Controls the appearance of the endpoints for each side of the line. The diagram below shows samples of each type of endpoint.
Each endpoint has an associated Scale that determines the size of the endpoint in relation to the Line Width. By default, it is set to Auto and will automatically adjust as the Line Width is changed.
