The Pen tool is used for free form text, shapes or other unique markups.
Tips for using the Pen tool:
Note: The Pen tool and Touchscreen functionality can be used simultaneously.
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.
Select a markup to reveal its control handles. Each handle controls a different aspect of the markup's size and orientation.
To rotate the markup, click and drag the orange handle outside the markup (when the markup is first placed, it will be at the top). By default, the markup is rotated in increments of 15°; to rotate in increments of 1°, hold down SHIFT while dragging.
The rotation can also be entered in the Rotation field found in the Layout section of the Properties tab.
To resize the markup, click and drag the appropriate yellow handle.
See Editing Markups for more information.
The appearance of the pen line is configurable, including its color, thickness, and opacity. Pen lines can also act as highlights, becoming fully transparent so as to let underlying content show through.
To change the appearance of a Pen markup, select it and click the Properties tab.
Color: Sets the color of the pen line.
Opacity: Sets the opacity level of the pen line as a percent, where 100% is completely opaque and 0% is completely transparent.
Line Width: Sets the thickness (in points) of the pen line.
Highlight: When enabled, makes the pen line appear completely transparent such that the underlying PDF content shows through without affecting its opacity.
