An Introduction PDF and Its Creation and Opening Methods

What Is PDF?

PDF, short for Portable Document Format, is a versatile file format created by Adobe that gives people an easy, reliable way to present and exchange documents – regardless of the software, hardware, or operating systems being used by anyone who views the document.

The reason is that the PDF file is based on the PostScript language and encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images, and other information needed to display it.

The PDF file uses an equivalent subset of the PostScript page description programming language for generating the layout and graphics, a font-embedding/replacement system to allow fonts to travel with the documents, and a structured storage system to bundle these elements and any associated content into a single file.

A PDF file is often a combination of vector graphics, text, and bitmap graphics. The basic types of content in a PDF are:

• Typeset text stored as content streams
• Vector graphics for illustrations and designs that consist of shapes and lines
• Raster graphics for photographs and other types of images
• Audio, video, and other multimedia objects
• Interactive elements such as annotations, form fields, links, and buttons
• Three-dimensional objects using U3D or PRC
• Digital signatures, file attachments, and metadata
• Layers
• Any other types of embedded content that can be handled using plug-ins
• And so on
