Click to select line annotations, as detailed in the lower annotation in the image above. Selected annotations can be edited as follows:
•Click and drag the yellow control points to reposition line endings. Hold down Shift to reposition annotations at increments of fifteen degrees.
•Click and drag, or use the arrow keys, to resposition annotations. Hold down Shift to move at an increased increment when using the arrow keys.
•Use the editing aids detailed here to assist in the precise placement of line annotations.
•Right-click annotations for further options, as detailed here.
•Press Ctrl+' to open the Properties pane for selected annotations and view/edit properties:
Figure 3. Line Tool, Line Properties Pane
•Subject is the name of the line annotation, as referenced in the Comments pane.
•Author is the name of the user that created the line annotation.
•Name is the unique name of the line annotation, as referenced within the application.
•Created is the date and time at which the line annotation was created.
•Modified is the date and time at which the line annotation was last modified.
•Read Only is the read only status of the line annotation. If this property is enabled then users cannot interact with the annotation.
•Printable is the print status of the line annotation. If this property is enabled then the annotation is printed with the document. If this property is not enabled then the annotation is not printed.
•Locked is the locked status of the line annotation. If this property is enabled then the annotation cannot be deleted and its properties (including its position and size) cannot be modified by users.
•Layer specifies the optional content layer to which the line annotation belongs. Further information about layers is available here.
•Fill Color determines the color of the line ending style used at the start of the line annotation. The line ending property is detailed below.
•Stroke Color determines the color of the line annotation.
•Opacity determines the level of transparency in the line annotation.
•Blend Mode determines how line annotations blend with overlapping content. These options are explained here.
•Start determines the line ending style used at the start of the line annotation.
•End determines the line ending style used at the end of the line annotation.
•Start Scale determines the size of the line ending used at the start of the line annotation.
•End Scale determines the size of the line ending used at the end of the line annotation.
•Leader Length determines the length of the leader lines used for the line annotation. Leader lines extend from each endpoint of the line annotation, perpendicular to the annotation itself.
•Leader Extension determines the length of leader line extensions that extend from the line annotation.
•Leader Offset determines the length of the leader line offset, which is the amount of empty space between the endpoints of the line annotation and the beginning of the leader lines.
•Show Caption determines whether or not the text contained in the pop-up note of the annotation is displayed.
•Inline Caption is not currently available but will be available in a future build.
•Length determines the length of the line annotation.
Note that when the Line Tool is enabled, the Format tab is available and can be used to customize the default properties of line annotations:
Figure 4. Format Tab, Line Tool
•Click options in the Shape Style group to select alternative default line annotation styles.
•Click Keep Selected to keep the Line Tool enabled and add multiple line annotations to the document. If this option is not enabled then PDF-XChange Editor will revert to the designated default tool immediately after creating one line annotation.
•Click Exclusive Mode to enable exclusive mode, which simplifies the process of using the Line Tool. When Exclusive Mode is enabled, the pointer ignores all interactive elements of documents other than base content. This makes it possible to create line annotations 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 open the Properties pane and view/edit Line Tool properties, as detailed above.
•When line annotations are selected, the Style Tools dropdown menu is available in the Format tab. It contains the following options:
•Click Copy Comment Style to copy the style properties of line annotations.
•Click Apply Copied Comment Style to apply a copied line annotation style to selected annotations.
•Click Apply Copied Comment Appearance to apply a copied line annotation style to selected annotations.
•Click Make Current Properties Default to set the properties of the line annotation as the default properties for subsequent annotations.
•Click Apply Default Properties to apply the default line annotation properties to selected line annotations.
•When line annotations are selected, the Pop-up group is available in the Format tab and can be used to interact with the pop-up note of the annotation:
•Click Open to open the pop-up note.
•Click Hide to hide the pop-up note.
•Click Reset Location to reset the location of the pop-up note.
•When line annotations are selected, the Arrange tab is also available and can be used to manipulate comments as detailed here.
Note that the Comment Styles Palette can be used to edit and save customized line annotation styles for subsequent use, and the Commenting preferences can be used to view/edit preferences for all comments.
