The Line tool draws a straight line segment. Segments can be at any angle and easily forced to be horizontal, vertical, or at a 45° angle on the page.
You can attach a note to nearly any markup that does not have a text box of its own. Simply double-click the markup to open the Note pop-up window. Notes attached to markups are functionally similar to the Note Tool.
You can add an action to nearly any markup. Simply right-click the markup and select Edit Action to open the Action dialog box.
Markups might present with one or more of several indicator icons alerting users of certain conditions or attachments. These icon indicators appear below the markup to the right (or, in the case of grouped markups, below and to the right of the group) and include:
Action: Indicates that an action has been defined for this markup. Clicking this icon triggers the action.
Capture: Indicates that the markup has an embedded media, typically an image or video. Clicking this icon opens a preview window showing the embedded media (or first piece of media, if multiple are embedded) and provides easy access to several useful tools.
Reply: Indicates the existence of one or more replies to the markup in the Markups list. Hovering over the icon previews the replies and clicking it opens the Markups list (if it's not already open) and jumps directly to the markup's entry there. Users can turn off the ability to see reply indicators in the View menu.
Select a markup to reveal its control handles. Each handle controls a different aspect of the markup's size and orientation.
To resize the markup or change its angle, click and drag the appropriate yellow handle. Hold down SHIFT while dragging to force the markup to a horizontal, vertical, or 45° angle.
See Editing Markups for more information.
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 it and click the Properties panel.
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.
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.
