PDF often refers to the Portable Document Format in computing.
PDF, pdf, Pdf, PdF or similar may also refer to:
IDF or idf may refer to:
Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file 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. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991.
SDF may refer to:
The principle of maximum entropy states that the probability distribution which best represents the current state of knowledge about a system is the one with largest entropy, in the context of precisely stated prior data.
MDF may refer to:
PSF is an abbreviation that may refer to:
UDF may refer to:
PCF may refer to:
PFA or Pfa may refer to:
ADF may refer to:
CDF is a three-letter acronym that may refer to:
TDF may refer to:
EDF may refer to:
PMF may stand for:
BDF or Bdf may refer to:
In statistics and information theory, a maximum entropy probability distribution has entropy that is at least as great as that of all other members of a specified class of probability distributions. According to the principle of maximum entropy, if nothing is known about a distribution except that it belongs to a certain class, then the distribution with the largest entropy should be chosen as the least-informative default. The motivation is twofold: first, maximizing entropy minimizes the amount of prior information built into the distribution; second, many physical systems tend to move towards maximal entropy configurations over time.
Open XML Paper Specification is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388.
Earth Defense Force 2017 is a third-person shooter developed by Sandlot, and published by D3 Publisher, for the Xbox 360.

Earth Defense Force 3 was the best selling Games on Demand game in Japan for 2009. The game was released on the PlayStation Vita in Japan on 27 September 2012. It was released digital-only in North America on January 8, 2013 and in the PAL region on January 16, 2013. A port of the game was released for the Nintendo Switch in Japan on October 14, 2021.
RDF may refer to:
PDF/VT is an international standard published by ISO in August 2010 as ISO 16612-2. It defines the use of PDF as an exchange format optimized for variable and transactional printing. Built on top of PDF/X-4, it is the first variable-data printing (VDP) format which ensures modern International Color Consortium-based (ICC) color management through the use of ICC Output Intents. It adds the notion of encapsulated groups of graphic objects to support optimized efficient processing for repeating text, graphic or image content. Introducing the concept of document part metadata (DPM), it enables reliable and dynamic management of pages for High Volume Transactional Output (HVTO) print data, like record selection or postage optimization based on metadata.
