Portable Document Format - Wikipedia, the free encyclopedia |
 | | Each PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics that compose the document. |
 | | Importantly, PDF files do not encode information that is specific to the application software, hardware, or operating system used to create or view the document. |
 | | A PDF file of a map, for example, is often a combination of vector graphics, text, and raster graphics. |
