Select Document Properties in the Document menu. The Document Properties dialog box has six panels: Description, Security, Initial View, Custom, Fonts, and Reading.
Under Description you find the Standard fields, such as Title, Author, Subject, Keywords. These values can be modified. Other values, such as Creator, Created and Modified cannot be changed.
Under Advanced you find PDF Producer, PDF Version, File Size, Page Size, Location and Number of Pages.
For details see Security Properties.
The Initial View options define how the document will be displayed when it is opened. These options are stored in the document and will be followed by any capable PDF viewer program.
You can include custom defined application-specific key-value document property pairs to the PDF document.
Later, other document management applications can retrieve the information for post-processing.
For example, you can make a custom field searchable by defining it in the custom field list before building the index.
Use this to show all the fonts referenced in the document. This helps you to understand whether font substitution is used to show unavailable fonts; or if fonts are embedded in the document.
You can specify reading options: choose either left-to-right or right-to-left text direction and choose the language for reading the content in the Language selection box.
This product can read text in the language you chose at installation time. If a suitable version of Nuance® RealSpeak™ or OmniPage is available on your computer, you can select any language and voice that they offer.
If any property is modified, you will be prompted to save the document before closing it.
