Portable Document Format |
A file format developed by Adobe Systems for representing two dimensional documents in a device independent and resolution independent format |
Each PDF file encapsulates a complete description of a 2D document that includes the text, fonts, images, and 2D vector graphics that compose the document. Importantly, PDF files don't encode information that is specific to the application software, hardware, or operating system used to create or view the document. This feature ensures that a valid PDF will render exactly the same regardless of its origin or destination. PDF is also an open standard in the sense that anyone may create applications that read PDF files without having to pay royalties to Adobe Systems. |

The precise definition of the .txt format is not specified, but typically matches the format accepted by the system terminal or simple text editor. |
