Ellipse tool

1. Select the Ellipse tool using one of the following methods:
   • Go to Tools > Markup > Ellipse.
   • Select on the Shapes toolbar.
   • Press E on the keyboard.
2. Drag to define the size of the ellipse.
   • Alternatively, select two points to define the opposite corners of the shape.
   • To define a circle by its radius, hold down ALT and drag along the desired radius.

Tips:

• Hold down Shift while defining the shape to force the shape into a circle.

To remove markups from your PDF, do one of the following:

• Select the markup on the PDF or from the Markups list.
• Press Delete on your keyboard, or right-click and select Delete.

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.

You can add an action to almost any markup. Right-click the markup and select Edit Action.

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.

Select a markup to reveal its control handles. Each handle controls a different aspect of size and orientation.

Rotate the markup: Drag the orange handle outside the markup (default: 15° increments; hold Shift for 1° increments)

To resize the markup, drag the appropriate yellow handle.

• Use the side control handles (yellow squares) to stretch or compress the markup in a single direction.
• Use the corner control handles (yellow circles) to scale the markup up or down in multiple directions.
  • Hold down Shift while dragging a corner control handle to force the shape into a circle.

See Editing Markups for more information.

The appearance of the Ellipse markup is configurable, including its line and fill color, hatch pattern, line width and style, and opacity.

To change the appearance of an Ellipse 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: Sets a fill color.

Highlight: Makes the fill color and/or hatch pattern transparent so underlying content shows through.

Hatch: Sets a hatch pattern. The associated color selector sets the line color of the hatch pattern.

Scale: Sets the scale of the hatch pattern, from 50 (half the default scale) to 200 (twice the default scale).

Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).

Fill Opacity: Sets the fill and hatch pattern opacity, 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 to the standard line styles, there are several advanced styles and you can create Custom Line Styles, if desired.
