About PDF Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange.
PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system.
Each PDF file encapsulates a complete description of a fixed-layout 2D document that includes the text, fonts, images, and 2D vector graphics which compose the documents.
Text in PDF is represented by text elements in page content streams. A text element specifies that characters should be drawn at certain positions. The characters are specified using the encoding of a selected font resource.
