info


5.0	D

Specifies an object with properties from the document information dictionary in the PDF file. (See the PDF Reference). Standard entries are:

	Title

	Author

	Authors							(Acrobat 9.0)

	Subject

	Keywords

	Creator

	Producer

	CreationDate

	ModDate

	Trapped

For Acrobat, properties of this object are writeable and setting a property dirties the document. Additional document information fields can be added by setting non-standard properties.

In Adobe Reader, writing to any property in this object throws an exception.

Note: Standard entries are case insensitive, that is, info.Keywords is the same as info.keywords.

Acrobat 9.0 intoduces the Authors (authors) property of the info object. Use Authors to retrieve a seim-colon delimited list of authors. Author information is saved in the XMP metadata, and Doc.info.Authors retrieves the information from the metadata as an array. Individual authors can be accessed. See Example 3 (Acrobat 9.0) below.
