Cooperation with PDF Viewer Plus
Unless a more sophisticated Nuance PDF viewer/editor is found during the installation process, PDF Viewer Plus is installed together with Nuance PaperPort and closely cooperates with the latter in several ways.
To view and edit PDF items in PDF Viewer Plus
While working in the PaperPort desktop, double-click a PDF item to open it in PDF Viewer Plus, provided suitable settings have been made on the Desktop tab of the PaperPort Options dialog box which is accessible from the menu of the PaperPort button. PDF Viewer Plus locates the folder of the currently active item and opens it to read, edit, annotate, share, search, form-fill and add security attributes. Once you are ready with modifications and close PDF Viewer Plus, the item is displayed again in PaperPort with the new attributes.
To edit an image within a PDF document in ImageViewer
While working in PDF Viewer Plus, use its 
Select Image button to select an image within a PDF document and either double-click the image, or right-click it and choose Edit Image from the shortcut menu. The selected image is displayed in the Nuance ImageViewer program where you can use all available SET tools to enhance it. Once you are ready with modifications and close ImageViewer, the item is displayed again in PDF Viewer Plus with the new image attributes.
Note
A higher level of cooperation can be achieved and the full range of PaperPort and PDF editing capabilities can be utilized by upgrading to Nuance PDF Converter Professional (version 5.3 and above).
