Callout tool

1. Select the Callout tool using one of the following methods:
   • Go to Tools > Markup > Callout.
   • Select  on the Shapes toolbar.
   • Press Q on the keyboard.
2. Select where to set the location of the terminus at the end of the leader line.
3. Select where to set the location of the text box. The leader line will automatically connect to the callout box, which will be ready to accept text.
4. Enter the desired text. Press ALT+Z to autosize the text box to fit the text.
5. Select away from the text box or press ESC to finish.

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.

You can add more leader lines to a Callout, move existing leader lines so that they anchor to different sides, or remove any or all leader lines.

Add leader lines

As many leader lines as desired can be added to any or all sides of the markup. To add more leader lines, repeat the process described below.

1. Right-click anywhere inside the text box and select Add Leader. A leader line will appear.
2. The leader line automatically anchors to the text box at the nearest applicable control point. To anchor it to a different side, move your mouse toward the desired side and it will automatically re-anchor there.
3. Select the spot on the PDF where you want the leader line's terminus to be.

Multiple leader lines can originate from the same side of the markup, with their terminal points extending from the same bend (or "knee"). To do this, add a leader line as normal and set it to originate from the same side as an existing one; the terminal point will automatically extend away from the same knee.

Move leader lines

Leader lines can be moved from one side of the markup to another. When moving a leader line to a side that already has a leader line, it automatically merges with that leader line.

To move a leader line, select the control point on its bend (or "knee") and drag it to the desired side. The line's connection point will automatically shift, but the terminal point will remain in place.

When rotating a callout markup, the entire callout is rotated, including the leader line. As a result, the leader line will not remain in place.

Remove leader lines

Any or all of a Callout's leader lines can be removed. If all the leader lines are removed, the Callout's text box will remain on the PDF, functioning very much like a Text Box.

There are two ways to remove a leader line:

• Right-click on the desired leader and select  Delete Leader.

• Hold down the SHIFT key and select the control point at the leader line's terminus (you will need to select the markup first to expose its control points).

Removing all leader lines from a Callout will cause its icon to change in the Markups list to resemble one used for Text Box markups (), though it will still be categorized as a Callout, allowing for easier differentiation.

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

To rotate the markup, drag the orange handle. By default, the markup is rotated in increments of 1°; to rotate in increments of 15°, hold down CTRL while dragging.

To resize the markup, drag the appropriate yellow handle.

To move only the text box, select inside the text box and drag it to the desired location. Alternatively, drag the leader line (not its handles).

The leader line's terminus will remain where it is and the leader will automatically adjust to text box's new location.

To autosize the text box so that it fits the text, right-click it and select Autosize Tex Box, or select it and press ALT+Z.

To move only the leader terminus, drag its yellow control handle to a new location. The text box will remain in the same location.

To move the entire markup together, hold down ALT while moving any part of the markup.

To move the leader origin from one side of the markup to another, drag the leader line's bend (or "knee") control handle to the desired side. If there is already a leader line on that side, it will automatically merge with that leader line. See Moving Leader Lines for more information.

See Editing Markups for more information.

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.

The appearance of the text, text box, and leader lines of a Callout markup are all configurable.

The entire contents of a callout text box can be selected by selecting the text box. Once it has been selected, changing any of the font formatting options will apply to all text within the box.

To select particular words in a callout text box, select the box to make it active, then drag over the desired text. Any formatting you change in the Properties tab will only affect the selected text.

To edit the appearance of a Callout 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

The Appearance section of the Properties panel contains the following options:

Color: Sets the color of the text box and leader line, if any.

Fill Color: Controls the fill color of the text box.

Opacity: Sets transparency level for the text box and the leader line.

Fill Opacity: Sets transparency level (100 = opaque, 0 = completely transparent) for the fill color.

Line Width: Sets the thickness of the line segment in points. If the Line Width is set to 0, it is effectively invisible.

Style: Determines the pattern of the line segment. The Cloud style only affects the text box; the leader line (when applicable) is solid. Any styles other than Cloud affects both the text box and the leader line.

Size: Sets the width of the cloud segments. Only applies when Style is set to Cloud.

Invert: Inverts the cloud segments inward on the shape. Only applies when Style is set to Cloud.

Shape: Sets the shape of the text box. Options include Rectangle, Circle, Triangle, and Hexagon. Note that if no Line Width has been set for the text box and the shape is changed, the line width is automatically set to "1.00". This can be changed afterward, if needed.

End: Controls the appearance of the terminal point of the line.

• Select the first list to choose a different terminus type.
• Select the second list to choose the size of the line's terminal point (if any).
• Select the color button to change the color of a filled teriminal point, if applicable.

Font: Sets the font used for the selected text. Available fonts are divided into three regions:

• The first region shows all fonts used in the currently selected text element.
• The second region lists the standard PDF fonts that are supported by all PDF viewers. These fonts don't need to be embedded in the PDF when used, thereby cutting down on file size.
• The third region shows all other available fonts. When used, these fonts need to be embedded in the PDF.

If you attempt to embed a font for which the viewing and editing permissions do not allow formatting, Revu will display a message indicating the font will not be embedded in the PDF.

Font settings are retained in the PDF and will substitute as needed if the original font is unavailable.

Font Size: Sets the font size for text. You can choose a size from 2 to 72 points in the list, or enter any value from 1 to 144 points manually. You can also use decimal values with one digit after the decimal point.

Auto: Automatically adjusts the font size of the text to the maximum value that will fit in the text box.

Line Space: Adjusts the spacing between multi-line rows of text.

Margin: Defines the amount of space between the text characters and the border of the Text Box.

Text Color: Sets the color of text.

Alignment: Defines the alignment of text within the box. The icons represent Left, Center, Right, Top Justified, Middle Justified and Bottom Justified respectively.

The Font Style settings control the formatting of the text. Options include Bold, Italic, Underline, Strikethrough, Superscript and Subscript. Generally, any combination of these styles can be applied to format the text.
