Logical structure and accessibility[ edit ] A "tagged" PDF see clause Technically speaking, tagged PDF is a stylized use of the format that builds on the logical structure framework introduced in PDF 1.
Tagged PDF defines a set of standard structure types and attributes that allow page content text, graphics, and images to be extracted and reused for other purposes.
Layers, or as they are more formally known Optional Content Groups OCGs , refer to sections of content in a PDF document that can be selectively viewed or hidden by document authors or consumers.
This capability is useful in CAD drawings, layered artwork, maps, multi-language documents etc. Basically, it consists of an Optional Content Properties Dictionary added to the document root.
This dictionary contains an array of Optional Content Groups OCGs , each describing a set of information and each of which may be individually displayed or suppressed, plus a set of Optional Content Configuration Dictionaries, which give the status Displayed or Suppressed of the given OCGs.
Security and signatures[ edit ] A PDF file may be encrypted for security, or digitally signed for authentication. The user password encrypts the file, while the owner password does not, instead relying on client software to respect these restrictions. An owner password can easily be removed by software, including some free online services.
Even without removing the password, most freeware or open source PDF readers ignore the permission "protections" and allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection.
Not only can they restrict document access but they also reliably enforce permissions in ways that the standard security handler does not. The signature is used to validate that the permissions have been granted by a bona fide granting authority. Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority.
