Figure 1. Tools Tab Submenu, Callout Tool
Callout annotations are used to highlight specific locations in documents. They are composed of a text box that features a linked arrow annotation, which is used to highlight the area of importance in the document.
When the Callout Tool is selected, click to add callout annotations. The position of the pointer when the mouse is clicked determines the initial position of the arrowhead in the callout arm. Detailed below are callout annotations at three stages of editing:
Figure 2. Callout Tool Examples
•The upper image is how a callout annotation appears when it is first inserted into a document. Enter the desired text using the keyboard. Press Enter to start new lines. Text style options are enabled in the Properties Toolbar when text is being entered. See here for an explanation of these options.
•The central image is how a callout annotation appears when text is being entered. Right-click callout annotations to launch the text editing options menu. Text editing options are explained here.
•The lower image is how a callout annotation appears when it is completed and subsequently selected.
•Click and drag the control points to resize callout annotations and/or reposition the callout arrow.
•Click and drag callout annotations to reposition them.
•Click and drag the green control point to rotate callout annotations. Hold down Shift to rotate at increments of fifteen degrees.
•Use the arrow keys to reposition callout annotations. Hold down Shift to move at an increased increment.
•Use the editing aids detailed here to assist in the precise placement of callout annotations.
•Right-click callout annotations for further options. See here for an explanation of these options.
•When the Callout Tool is selected, the following options are enabled in the Properties Toolbar:
•Fill Color determines the color of the callout annotation.
•Stroke Color determines the the border color of the callout annotation.
•Border Style determines the style of the border used around the callout annotation.
•Border Width determines the width of the border used around callout annotation.
•Line Ending Style determines the shape at the end of the arm that comes from the callout annotation.
•Opacity determines the level of transparency for callout annotations and their content.
•Blend Mode determines how callouts blend with underlying content. These options are explained here.
•Auto Adjust Arm Position relates to the callout arm. When this setting is disabled the control point from which the callout arm originates remains constant when callout annotations are repositioned. When this setting is enabled the control point from which callout arms originate changes automatically. The control point closest to the end of the callout arm will be used.
•Keep Selected determines whether or not the Callout Tool remains selected after a callout annotation has been created. If this option is enabled then the tool will remain selected and can be used to create several callout annotations consecutively. If this option is not enabled then PDF-XChange Editor will revert to the designated default tool immediately after creating a callout text annotation.
•Exclusive Mode simplifies the process of using the Callout Tool. When Exclusive Mode is enabled, the pointer ignores all interactive elements of documents other than base content. This makes it possible to create callouts on areas that overlap with other content without the risk of accidentally selecting undesired items. When Exclusive Mode is disabled, the pointer recognizes and interacts with all underlying elements in the usual manner.
•Click Properties to view/edit additional callout properties, as detailed below.
•Note that several default styles are available for callout annotations, as detailed in (figure 1). Click to select alternative annotation styles. The Comment Styles Palette can be used to save customized callout annotation styles for subsequent use. Right-click the Callout icon in the Comment Toolbar to view existing styles and/or access the Comment Styles Palette.
•The Commenting section of the Preferences dialog box can be used to view/edit preferences for comments.
Please note that to select text after a callout text box has been completed it is necessary to click to select the callout text box and then click again to select the text. This is because PDF-XChange Editor must recognize callout text boxes and the text that they contain as separate items as they feature different editing options. See here for information on editing callout text boxes.
Figure 3. Callout Properties Pane
•Subject is the name of the callout comment, as referenced in the Comments pane.
•Author is the name of the user that created the callout comment.
•Name is the unique name of the callout comment, as referenced within the application.
•Created is the date and time at which the callout comment was created.
•Modified is the date and time at which the callout annotation was last modified.
•Printable is the print status of the callout annotation. If this property is enabled then the comment is printed with the document. If this property is not enabled then the comment is not printed.
•Locked is the locked status of the callout annotation. If this property is enabled then the comment cannot be deleted and its properties (including its position and size) cannot be modified by users.
•Layer is the optional content layer to which the callout annotation belongs. Further information about layers is available here.
•Fill Color determines the color of the callout annotation.
•Stroke Color determines the border color of the callout annotation.
•Border Style determines the border style of the callout annotation
•Border Width determines the border width of the callout annotation.
•Opacity determines the level of transparency in the callout annotation.
•Blend Mode determines how the callout annotation blends with overlapping content, as detailed here.
•Rotation determines the degrees of rotation of the callout annotation.
•End determines the line ending used for the arm of the callout annotation.
•End Scale determines the size of the line ending in relation to the rest of the callout annotation.
