Adobe Acrobat 4.0

This second edition covers additional security features in Acrobat 4.0 that were previously available only to Windows users, but are now available for Macintosh as well. The authors focus on Web Capture (the ability to create PDF files from Web sites), Digital Signatures (allows for electronic sign-off of shared files), Compare Pages, (the ability to open more than one file in separate windows), Send Mail (the ability to automatically attach a PDF file to an email document) and Web Buy, a new tool for sharing files that require a key to access them.
