WWF (file Format)
WWF is a modification of the open standard Portable Document Format, PDF format for document exchange endorsed by the World Wide Fund for Nature (also abbreviated WWF) Germany. The WWF format is promoted as being more environmentally friendly than other comparable document exchange formats (e.g. Portable Document Format, PDF or DOC (computing), DOC) since documents in this format are designed to be more difficult to print. The motivation behind the use of the format is to prevent unnecessary printing of documents. The website claims that the file format will be able to be read by most programs that can open ordinary PDF files. At present, the software for creating WWF files is available for Mac OS X Tiger, Mac OS X 10.4 and for Windows XP and later. An open-source equivalent is available for Linux and for Windows XP and later. Technical details WWF files are simply Portable Document Format, PDF files with the security settings for printing set to "not allowed", and the file ext ...

Open Standard
An open standard is a standard that is openly accessible and usable by anyone. It is also a common prerequisite that open standards use an open license that provides for extensibility. Typically, anybody can participate in their development due to their inherently open nature. There is no single definition, and interpretations vary with usage. Examples of open standards include the GSM, 4G, and 5G standards that allow most modern mobile phones to work world-wide. Definitions The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis ...

Ghostscript
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization of documents in these language,, the display or printing of document pages, and conversion between PostScript and PDF files. Features Ghostscript can be used as a raster image processor (RIP) for raster computer printers—for instance, as an input filter of line printer daemon—or as the RIP engine behind PostScript and PDF viewers. It can also be used as a file format converter, such as PostScript to PDF converter. The ps2pdf conversion program comes with the Ghostscript distribution. Ghostscript can also serve as the back-end for PDF to raster image (png, tiff, jpeg, etc.) converter; this is often combined with a PostScript printer driver in " virtual printer" PDF creators. As it takes the form of a language interpreter, Ghostscript can also be used as a general purpose programming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer File Formats
A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or open. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container for different types of multimedia including any combination of audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various character encoding schemes. Some file formats, such as HTML, scalable vector graphics, and the source code of computer software are text files with defined syntaxes that allow them to be used for specific purposes.

Vector Graphics
Vector graphics are a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing ''hardware'', vector ''data models'' and file formats, as well as the ''software'' based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics are an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continue to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Formats
An open file format is a file format for storing Data (computing), digital data, defined by an openly published specification usually maintained by a standards organization, and which can be used and implemented by anyone. An open file format is licensed with an open license. For example, an open format can be implemented by both proprietary software, proprietary and free software, free and open-source software, using the typical software licenses used by each. In contrast to open file formats, Proprietary file format, closed file formats are considered trade secrets. Depending on the definition, the specification of an open format may require a fee to access or, very rarely, contain other restrictions. The range of meanings is similar to that of the term open standard. Specific definitions UK government In 2012 the UK Government created the policy Open Standards Principles, stating that the Open Standards Principles apply to every aspect of government IT and that Government ...

Graphics File Formats
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency. Raster formats are for 2D images. A 3D image can be represented within a 2D format, as in a stereogram or autostereogram, but this 3D image will not be a true light field, and thereby may cause the vergence-accommodation conflict. Image files are composed of digital data in one of these formats so that the data can be displayed on a digital (computer) display or printed out using a printer. A common method for displaying digital image information has historically been rasterization. Image file sizes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoning Home
In computing, phoning home is a term often used to refer to the behavior of security systems that report network location, username, or other such data to another computer. Phoning home may be useful for the proprietor in tracking a missing or stolen computer. In this way, it is frequently performed by mobile computers at corporations. It typically involves a software agent which is difficult to detect or remove. However, phoning home can also be malicious, as in surreptitious communication between end-user applications or hardware and its manufacturers or developers. The traffic may be encrypted to make it difficult or impractical for the end user to determine what data are being transmitted. The Stuxnet attack on Iran's nuclear facilities was facilitated by phone-home technology, as reported by ''The New York Times''. Legally phoning home Some uses for the practice are legal in some countries. For example, phoning home could be for access restriction, such as transmitting an a ...

Free And Open Source Software
Free and open-source software (FOSS) is software available under a Software license, license that grants users the right to use, modify, and distribute the software modified or not to everyone free of charge. FOSS is an inclusive umbrella term encompassing free software and open-source software. The rights guaranteed by FOSS originate from the "Four Essential Freedoms" of ''The Free Software Definition'' and the criteria of ''The Open Source Definition''. All FOSS can have publicly available source code, but not all source-available software is FOSS. FOSS is the opposite of proprietary software, which is licensed restrictively or has undisclosed source code. The historical precursor to FOSS was the hobbyist and academic public domain software ecosystem of the 1960s to 1980s. Free and open-source operating systems such as Linux distributions and descendants of BSD are widely used, powering millions of server (computing), servers, desktop computer, desktops, smartphones, and othe ...

BSD License
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In addition ...

Portable Document Format
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. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020. 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.
