Portable Document Format PDF , standardized as ISO , is a file format developed by Adobe in to present documents , including text formatting and images, in a manner independent of application software , hardware , and operating systems.

PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media including video content , three-dimensional objects using U3D or PRC , and various other data formats. The PDF specification also provides for encryption and digital signatures , file attachments, and metadata to enable workflows requiring these features.

Adobe Systems made the PDF specification available free of charge in PDF was a proprietary format controlled by Adobe until it was released as an open standard on July 1, , and published by the International Organization for Standardization as ISO , [6] [7] at which time control of the specification passed to an ISO Committee of volunteer industry experts.

In , Adobe published a Public Patent License to ISO granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF-compliant implementations. PDF 1. In December , the second edition of PDF 2. A PDF file is often a combination of vector graphics , text, and bitmap graphics. The basic types of content in a PDF are.

PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. It can handle graphics and standard features of programming languages such as if statements and loop commands.

PDF is largely based on PostScript but simplified to remove flow control features like these, while graphics commands equivalent to lineto remain. The graphics commands that are output by the PostScript code are collected and tokenized.

Then, everything is compressed to a single file. Therefore, the entire PostScript world fonts, layout, measurements remains intact. Comments may contain 8-bit characters. Objects may be either direct embedded in another object or indirect. Indirect objects are numbered with an object number and a generation number and defined between the obj and endobj keywords if residing in the document root.

Beginning with PDF version 1. This technique enables non-stream objects to have standard stream filters applied to them, reduces the size of files that have large numbers of small indirect objects and is especially useful for Tagged PDF. Object streams do not support specifying an object’s generation number other than 0. An index table, also called the cross-reference table, is located near the end of the file and gives the byte offset of each indirect object from the start of the file.

Before PDF version 1. Version 1. Such a stream may be used instead of the ASCII cross-reference table and contains the offsets and other information in binary format. If a cross-reference stream is not being used, the footer is preceded by the trailer keyword followed by a dictionary containing information that would otherwise be contained in the cross-reference stream object’s dictionary:.

Within each page, there are one or multiple content streams that describe the text, vector and images being drawn on the page. The content stream is stack-based , similar to PostScript. There are two layouts to the PDF files: non-linearized not “optimized” and linearized “optimized”. Non-linearized PDF files can be smaller than their linear counterparts, though they are slower to access because portions of the data required to assemble pages of the document are scattered throughout the PDF file.

Linearized PDF files also called “optimized” or “web optimized” PDF files are constructed in a manner that enables them to be read in a Web browser plugin without waiting for the entire file to download, since all objects required for the first page to display are optimally organized at the start of the file.

The basic design of how graphics are represented in PDF is very similar to that of PostScript , except for the use of transparency , which was added in PDF 1. PDF graphics use a device-independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale , rotate , or skew graphical elements. A key concept in PDF is that of the graphics state , which is a collection of graphical parameters that may be changed, saved, and restored by a page description.

PDF has as of version 2. Paths can be stroked, filled, fill then stroked, or used for clipping. Strokes and fills can use any color set in the graphics state, including patterns.

PDF supports several types of patterns. The simplest is the tiling pattern in which a piece of artwork is specified to be drawn repeatedly. This may be a colored tiling pattern , with the colors specified in the pattern object, or an uncolored tiling pattern , which defers color specification to the time the pattern is drawn. Beginning with PDF 1. There are seven types of shading patterns of which the simplest are the axial shading Type 2 and radial shading Type 3.

The dictionary describes the properties of the image, and the stream contains the image data. Less commonly, small raster images may be embedded directly in a page description as an inline image.

Images are typically filtered for compression purposes. Image filters supported in PDF include the following general-purpose filters:. Normally all image content in a PDF is embedded in the file.
