Click the Polygon Tool to add polygon annotations to documents:
Figure 1. Comment Tab, Polygon Tool
When the Polygon Tool is enabled, click to designate the first point of the polygon, then move the pointer to the next location and click to designate the second point. Repeat this process until the final point of the desired shape is reached and then double-click to complete the polygon:
Figure 2. Polygon Tool Examples
Click to select polygon annotations, as detailed in the lower annotation in the image above. Selected annotations can be edited as follows:
•Click and drag the outer control points to resize polygons.
•Click and drag the inner control points to reposition polygons.
•Click and drag to reposition polygons. The circle at the center can also be used for this purpose.
•Click and drag the green control point at the top to rotate polygons. Hold down Shift to rotate at increments of fifteen degrees.
•Use the arrow keys to reposition polygons. Hold down Shift to move at an increased increment.
•Use the editing aids detailed here to assist in the precise placement of polygons.
•Right-click polygons for further options. See here for an explanation of these options.
•Press Ctrl+' to open the Properties pane for selected annotations and view/edit properties:
Figure 3. Polygon Tool, Polygon Properties Pane
•Subject is the name of the polygon annotation, as referenced in the Comments pane.
•Author is the name of the user that created the polygon annotation.
•Name is the unique name of the polygon annotation, as referenced within the application.
•Created is the date and time at which the polygon annotation was created.
•Modified is the date and time at which the polygon annotation was last modified.
•Printable is the print status of the polygon 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 polygon 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 polygon 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 polygon annotation. The line ending property is detailed below.
•Stroke Color determines the color of the polygon annotation.
•Border Style determines the style of the annotation.
•Border Width determines the width of the annotation.
•Opacity determines the level of transparency in the polygon annotation.
•Blend Mode determines how polygon annotations blend with overlapping content. These options are explained here.
•Rotation determines the degrees of rotation of the polygon annotation.
Note that when the Polygon Tool is enabled, the Format tab is available and can be used to customize the default properties of polygon annotations:
Figure 4. Format Tab, Polygon Tool
•Click options in the Shape Style group to select alternative default polygon annotation styles.
•Click Keep Selected to keep the Polygon Tool enabled and add multiple polygon 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 polygon annotation.
•Click Exclusive Mode to enable exclusive mode, which simplifies the process of using the Polygon Tool. When Exclusive Mode is enabled, the pointer ignores all interactive elements of documents other than base content. This makes it possible to create polygon 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 Polygon Tool properties, as detailed above.
•When polygon 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 polygon annotations.
•Click Apply Copied Comment Style to apply a copied polygon annotation style to selected annotations.
•Click Apply Copied Comment Appearance to apply a copied polygon annotation style to selected annotations.
•Click Make Current Properties Default to set the properties of the polygon annotation as the default properties for subsequent annotations.
•Click Apply Default Properties to apply the default polygon annotation properties to selected polygon annotations.
•When polygon 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 polygon 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 polygon annotation styles for subsequent use, and the Commenting preferences can be used to view/edit preferences for all comments.
Convert Polygon Annotations to Area Annotations
If you want to convert polygon line annotations to area annotations, then right-click the polygon line annotation and click Convert to Measurement:
Figure 5. Right-Click Shortcut Menu, Convert to Measurement Highlighted
The polygon line annotation will then convert into an area annotation. Note that it is possible to convert multiple annotations at the same time.
