•Rotation determines the degrees of rotation of the perimeter annotation.
•Start determines the line ending style used at the start of the perimeter annotation.
•End determines the line ending style used at the end of the perimeter annotation.
•Start Scale determines the size of the line ending used at the start of the perimeter annotation.
•End Scale determines the size of the line ending used at the end of the perimeter annotation.
•Scale determines the scale used for the perimeter annotation. Further information about scales is available here.
Note that when the Perimeter Tool is enabled, the Format tab is available and can be used to customize the default properties of perimeter annotations:
Figure 4. Format Tab, Perimeter Tool
•Click options in the Shape Style group to select alternative default perimeter annotation styles.
•Click Keep Selected to keep the Perimeter Tool selected and create multiple lines consecutively. If this option is disabled then PDF-XChange Editor will revert to the designated default tool after the creation of one line.
•Click Exclusive Mode to give the Perimeter Tool priority over all other document content. When Exclusive Mode is enabled, the pointer ignores all interactive elements of documents other than base content. This makes it possible to create lines 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 content as normal.
•Click Properties to view/edit the Perimeter Tool properties, as detailed above.
•Click Export to CSV to export the document to a comma-separated-values document.
•Click Edit Label to create/edit the text label of the perimeter annotation, or click Delete Label to delete the label. Note that labels are displayed when the pointer is hovered over the annotation.
•When perimeter 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 perimeter annotations.
•Click Apply Copied Comment Style to apply a copied perimeter annotation style to selected annotations.
•Click Apply Copied Comment Appearance to apply a copied perimeter annotation style to selected annotations.
•Click Make Current Properties Default to set the properties of the perimeter annotation as the default properties for subsequent annotations.
•Click Apply Default Properties to apply the default perimeter annotation properties to selected perimeter annotations.
•When perimeter 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 perimeter annotations are selected, the Arrange tab is also available and can be used to manipulate comments as detailed here.
