82-429: WIC enables application developers to perform image processing operations on any image format through a single set of common APIs , without requiring prior knowledge of specific image formats. Windows Imaging Component provides an extensible architecture for image codecs, pixel formats, and metadata, with automatic run-time discovery of new formats. It supports reading and writing of arbitrary metadata in image files, with

164-544: A procedural language such as Lua could consist primarily of basic routines to execute code, manipulate data or handle errors while an API for an object-oriented language , such as Java, would provide a specification of classes and its class methods . Hyrum's law states that "With a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system will be depended on by somebody." Meanwhile, several studies show that most applications that use an API tend to use

246-420: A software framework : a framework can be based on several libraries implementing several APIs, but unlike the normal use of an API, the access to the behavior built into the framework is mediated by extending its content with new classes plugged into the framework itself. Moreover, the overall program flow of control can be out of the control of the caller and in the framework's hands by inversion of control or

328-453: A WIC codec is installed. Office 2010 and later versions of the core Office apps (Word, Excel, PowerPoint and Outlook) can import image file formats supported by WIC. Starting with Windows 7, Windows Media Center (available on Windows 7 Home Premium and above) is WIC-enabled. Also, the GDI+ graphic library is built on WIC, although GDI+ does not load 3rd-party or external codecs. With Windows 7

410-449: A broad term describing much of the communication on the internet. When used in this way, the term API has overlap in meaning with the term communication protocol . The interface to a software library is one type of API. The API describes and prescribes the "expected behavior" (a specification) while the library is an "actual implementation" of this set of rules. A single API can have multiple implementations (or none, being abstract) in

492-517: A business ecosystem. The main policies for releasing an API are: An important factor when an API becomes public is its "interface stability". Changes to the API—for example adding new parameters to a function call—could break compatibility with the clients that depend on that API. When parts of a publicly presented API are subject to change and thus not stable, such parts of a particular API should be documented explicitly as "unstable". For example, in

574-460: A client would need to know for practical purposes. Documentation is crucial for the development and maintenance of applications using the API. API documentation is traditionally found in documentation files but can also be found in social media such as blogs, forums, and Q&A websites. Traditional documentation files are often presented via a documentation system, such as Javadoc or Pydoc, that has

656-453: A color on the canvas. The built-in color choosers include RGB / HSV / LAB / LCH selector or scales, water-color selector, CMYK selector and a color-wheel selector. Colors can also be selected using hexadecimal color codes, as used in HTML color selection. GIMP has native support for indexed color and RGB color spaces; other color spaces are supported using decomposition, where each channel of

738-470: A complete image. The fourth channel that may be part of a layer is the alpha channel (or layer mask). This channel measures opacity where a whole or part of an image can be completely visible, partially visible or invisible. Each layer has a layer mode that can be set to change the colors in the image. Text layers can be created using the text tool, allowing a user to write on an image. Text layers can be transformed in several ways, such as converting them to

820-412: A connection between computers or between computer programs . It is a type of software interface , offering a service to other pieces of software . A document or standard that describes how to build such a connection or interface is called an API specification . A computer system that meets this standard is said to implement or expose an API. The term API may refer either to the specification or to

902-435: A consistent appearance and structure. However, the types of content included in the documentation differs from API to API. In the interest of clarity, API documentation may include a description of classes and methods in the API as well as "typical usage scenarios, code snippets, design rationales, performance discussions, and contracts", but implementation details of the API services themselves are usually omitted. It can take

984-453: A different user interface. Also, as of 2024 and version 2.10, a fundamental and essential difference between GIMP, on one hand, and major commercial software like Photoshop and Serif Affinity Photo , on the other, is that very few of GIMP's editing operations occur as non-destructive edits , unlike the main commercial software. There are several ways of selecting colors, including palettes, color choosers and using an eyedropper tool to select

1066-534: A given API, it is possible to infer the typical usages, as well the required contracts and directives. Then, templates can be used to generate natural language from the mined data. In 2010, Oracle Corporation sued Google for having distributed a new implementation of Java embedded in the Android operating system. Google had not acquired any permission to reproduce the Java API, although permission had been given to

1148-441: A modular software library in the 1940s for EDSAC , an early computer. The subroutines in this library were stored on punched paper tape organized in a filing cabinet . This cabinet also contained what Wilkes and Wheeler called a "library catalog" of notes about each subroutine and how to incorporate it into a program. Today, such a catalog would be called an API (or an API specification or API documentation) because it instructs

1230-417: A new software product. The process of joining is called integration . As an example, consider a weather sensor that offers an API. When a certain message is transmitted to the sensor, it will detect the current weather conditions and reply with a weather report. The message that activates the sensor is an API call , and the weather report is an API response . A weather forecasting app might integrate with

1312-400: A normal sharpening filter. The Selective Gaussian Blur tool works in a similar way, except it blurs areas of an image with little detail. GIMP-ML is an extension for machine learning with 15 filters. The Generic Graphics Library ( GEGL ) was first introduced as part of GIMP on the 2.6 release of GIMP. This initial introduction does not yet exploit all of the capabilities of GEGL; as of

1394-401: A number of default gradients included with GIMP; a user can also create custom gradients with tools provided. Gradient plug-ins are also available. GIMP selection tools include a rectangular and circular selection tool, free select tool, and fuzzy select tool (also known as magic wand). More advanced selection tools include the select by color tool for selecting contiguous regions of color—and

1476-470: A number of forms, including instructional documents, tutorials, and reference works. It'll also include a variety of information types, including guides and functionalities. Restrictions and limitations on how the API can be used are also covered by the documentation. For instance, documentation for an API function could note that its parameters cannot be null, that the function itself is not thread safe . Because API documentation tends to be comprehensive, it

1558-414: A number of weather sensor APIs, gathering weather data from throughout a geographical area. An API is often compared to a contract . It represents an agreement between parties: a service provider who offers the API and the software developers who rely upon it. If the API remains stable, or if it changes only in predictable ways, developers' confidence in the API will increase. This may increase their use of

1640-596: A paint brush, pencil, airbrush, eraser and ink tools used to create new or blended pixels. The Bucket Fill tool can be used to fill a selection with a color or pattern. The Blend tool can be used to fill a selection with a color gradient. These color transitions can be applied to large regions or smaller custom path selections. GIMP also provides "smart" tools that use a more complex algorithm to do things that otherwise would be time-consuming or impossible. These include: An image being edited in GIMP can consist of many layers in

1722-639: A path or selection. GIMP has approximately 150 standard effects and filters, including Drop Shadow, Blur, Motion Blur and Noise. GIMP operations can be automated with scripting languages . The Script-Fu is a Scheme -based language implemented using a TinyScheme interpreter built into GIMP. GIMP can also be scripted in Perl , Python (Python-Fu), or Tcl , using interpreters external to GIMP. New features can be added to GIMP not only by changing program code (GIMP core), but also by creating plug-ins. These are external programs that are executed and controlled by

SECTION 20

#1732787158432

1804-440: A programmer on how to use (or "call") each subroutine that the programmer needs. Wilkes and Wheeler's book The Preparation of Programs for an Electronic Digital Computer contains the first published API specification. Joshua Bloch considers that Wilkes and Wheeler "latently invented" the API, because it is more of a concept that is discovered than invented. The term "application program interface" (without an -ing suffix)

1886-518: A programmer will find useful and keeping them consistent even if the internal details later change. An API may be custom-built for a particular pair of systems, or it may be a shared standard allowing interoperability among many systems. The term API is often used to refer to web APIs , which allow communication between computers that are joined by the internet . There are also APIs for programming languages , software libraries , computer operating systems , and computer hardware . APIs originated in

1968-555: A semester-long project at the University of California, Berkeley for the eXperimental Computing Facility . The acronym was coined first, with the letter G being added to -IMP as a reference to "the gimp" in the scene from the 1994 film Pulp Fiction . 1996 was the initial public release of GIMP (0.54). The editor was quickly adopted and a community of contributors formed. The community began developing tutorials and artwork and sharing better work-flows and techniques. In

2050-643: A shipping company API that can be added to an eCommerce-focused website to facilitate ordering shipping services and automatically include current shipping rates, without the site developer having to enter the shipper's rate table into a web database. While "web API" historically has been virtually synonymous with web service , the recent trend (so-called Web 2.0 ) has been moving away from Simple Object Access Protocol ( SOAP ) based web services and service-oriented architecture (SOA) towards more direct representational state transfer (REST) style web resources and resource-oriented architecture (ROA). Part of this trend

2132-404: A similar mechanism. An API can specify the interface between an application and the operating system . POSIX , for example, specifies a set of common APIs that aim to enable an application written for a POSIX conformant operating system to be compiled for another POSIX conformant operating system. Linux and Berkeley Software Distribution are examples of operating systems that implement

2214-401: A simple standalone third-party image viewer, supports standard image formats along with HD Photo and RAW camera formats (NRW, NEF, CR2, DNG) using WIC. An experimental WIC import plug-in for Adobe Photoshop can also be found on FastPictureViewer's website. Another WIC import plug-in for GIMP can be found at Gimp-Forum.net. API An application programming interface ( API ) is

2296-441: A small part of the API. Language bindings are also APIs. By mapping the features and capabilities of one language to an interface implemented in another language, a language binding allows a library or service written in one language to be used when developing in another language. Tools such as SWIG and F2PY, a Fortran -to- Python interface generator, facilitate the creation of such interfaces. An API can also be related to

2378-463: A software system, used for machine-to-machine communication. A well-designed API exposes only objects or actions needed by software or software developers. It hides details that have no use. This abstraction simplifies programming. Building software using APIs has been compared to using building-block toys, such as Lego bricks. Software services or software libraries are analogous to the bricks; they may be joined together via their APIs, composing

2460-448: A stack. The user manual suggests that "A good way to visualize a GIMP image is as a stack of transparencies," where in GIMP terminology, each level (analogous to a transparency) is called a layer. Each layer in an image is made up of several channels. In an RGB image, there are normally 3 or 4 channels, each consisting of a red, green and blue channel. Color sublayers look like slightly different gray images, but when put together they make

2542-482: A system of commands and thereby bar all others from writing its different versions to carry out all or part of the same commands. GIMP The GNU Image Manipulation Program , commonly known by its acronym GIMP ( / ɡ ɪ m p / GHIMP ), is a free and open-source raster graphics editor used for image manipulation (retouching) and image editing , free-form drawing, transcoding between different image file formats , and more specialized tasks. It

2624-653: Is "easy enough to try" despite not having as well developed documentation and help system as those for Photoshop, concluding that it "has become a worthy alternative to Photoshop for anyone on a budget who doesn't need all of Photoshop's vast feature set". The user interface has been criticized for being "hard to use". Tools used to perform image editing can be accessed via the toolbox, through menus and dialogue windows. They include filters and brushes, as well as transformation, selection, layer and masking tools. GIMP's developers have asserted that it has, or at least aspire to it having, similar functionality to Photoshop, but has

2706-454: Is a challenge for writers to keep the documentation updated and for users to read it carefully, potentially yielding bugs. API documentation can be enriched with metadata information like Java annotations . This metadata can be used by the compiler, tools, and by the run-time environment to implement custom behaviors or custom handling. It is possible to generate API documentation in a data-driven manner. By observing many programs that use

2788-512: Is an architectural approach that revolves around providing a program interface to a set of services to different applications serving different types of consumers. When used in the context of web development , an API is typically defined as a set of specifications, such as Hypertext Transfer Protocol (HTTP) request messages, along with a definition of the structure of response messages, usually in an Extensible Markup Language ( XML ) or JavaScript Object Notation ( JSON ) format. An example might be

2870-522: Is created in one place dynamically can be posted and updated to multiple locations on the web. For example, Twitter's REST API allows developers to access core Twitter data and the Search API provides methods for developers to interact with Twitter Search and trends data. The design of an API has significant impact on its usage. The principle of information hiding describes the role of programming interfaces as enabling modular programming by hiding

2952-452: Is extensible by means of plugins, and scriptable. It is not designed to be used for drawing, though some artists and creators have used it in this way. GIMP is released under the GPL-3.0-or-later license and is available for Linux , macOS , and Microsoft Windows . In 1995, Spencer Kimball and Peter Mattis began developing GIMP—originally named General Image Manipulation Program —as

3034-399: Is first recorded in a paper called Data structures and techniques for remote computer graphics presented at an AFIPS conference in 1968. The authors of this paper use the term to describe the interaction of an application—a graphics program in this case—with the rest of the computer system. A consistent application interface (consisting of Fortran subroutine calls) was intended to free

3116-419: Is included with GIMP 2.10. OpenCL enables hardware acceleration for some operations. CTX is a new rasterizer for vector graphics in GIMP 3.0. Some simple objects, like lines and circles, can be reduced to vector objects. GIMP supports importing and exporting with a large number of different file formats . GIMP's native format XCF is designed to store all information GIMP can contain about an image; XCF

3198-412: Is named after the e X perimental C omputing F acility where GIMP was authored. Import and export capability can be extended to additional file formats by means of plug-ins. XCF file size is extended to more than 4 GB since 2.9.6 and new stable tree 2.10.x. Because of the free and open-source nature of GIMP, several forks , variants and derivatives of the computer program have been created to fit

3280-453: Is now the most common meaning of the term API. The Semantic Web proposed by Tim Berners-Lee in 2001 included "semantic APIs" that recast the API as an open , distributed data interface rather than a software behavior interface. Proprietary interfaces and agents became more widespread than open ones, but the idea of the API as a data interface took hold. Because web APIs are widely used to exchange data of all kinds online, API has become

3362-653: Is often compared to and suggested as a possible replacement for Adobe Photoshop . GIMP 2.6 was used to create nearly all of the art in Lucas the Game , an independent video game by developer Timothy Courtney. Courtney started development of Lucas the Game in early 2014, and the video game was published in July 2015 for PC and Mac. Courtney explains GIMP is a powerful tool, fully capable of large professional projects, such as video games. The single-window mode introduced in GIMP 2.8

3444-636: Is per codec. For example, the native JPEG codec supports XMP but the native GIF and PNG codecs do not. WIC is available for Windows XP with Service Pack 2, as a stand-alone downloadable program, and is built into Windows XP with Service Pack 3. It is also available as part of .NET Framework 3.0 . A discontinued PowerToy for Windows XP from Microsoft, known as Photo Info, which allows viewing and editing image metadata from Windows Explorer, also uses WIC. Starting with Windows Vista, Windows Explorer , and Windows Photo Gallery , are based on WIC and can thus view and organize images in any format for which

3526-475: Is related to the Semantic Web movement toward Resource Description Framework (RDF), a concept to promote web-based ontology engineering technologies. Web APIs allow the combination of multiple APIs into new applications known as mashups . In the social media space, web APIs have allowed web communities to facilitate sharing content and data between communities and applications. In this way, content that

3608-549: The Google Guava library, the parts that are considered unstable, and that might change soon, are marked with the Java annotation @Beta . A public API can sometimes declare parts of itself as deprecated or rescinded. This usually means that part of the API should be considered a candidate for being removed, or modified in a backward incompatible way. Therefore, these changes allow developers to transition away from parts of

3690-686: The Java language in particular. In the 1990s, with the spread of the internet , standards like CORBA , COM , and DCOM competed to become the most common way to expose API services. Roy Fielding 's dissertation Architectural Styles and the Design of Network-based Software Architectures at UC Irvine in 2000 outlined Representational state transfer (REST) and described the idea of a "network-based Application Programming Interface" that Fielding contrasted with traditional "library-based" APIs. XML and JSON web APIs saw widespread commercial adoption beginning in 2000 and continuing as of 2021. The web API

3772-512: The Java remote method invocation API uses the Java Remote Method Protocol to allow invocation of functions that operate remotely, but appear local to the developer. Therefore, remote APIs are useful in maintaining the object abstraction in object-oriented programming ; a method call , executed locally on a proxy object, invokes the corresponding method on the remote object, using the remoting protocol, and acquires

3854-556: The Linux Standard Base provides an ABI. Remote APIs allow developers to manipulate remote resources through protocols , specific standards for communication that allow different technologies to work together, regardless of language or platform. For example, the Java Database Connectivity API allows developers to query many different types of databases with the same set of functions, while

3936-663: The Wilber Construction Kit , included in the GIMP source code as /docs/Wilber_Construction_Kit.xcf.gz . GIMP is primarily developed by volunteers as a free and open source software project associated with both the GNU and GNOME projects. Development takes place in a public git source code repository, on public mailing lists and in public chat channels on the GIMPNET IRC network. New features are held in public separate source code branches and merged into

4018-417: The 1940s, though the term did not emerge until the 1960s and 70s. An API opens a software system to interactions from the outside. It allows two software systems to communicate across a boundary — an interface — using mutually agreed-upon signals. In other words, an API connects software entities together. Unlike a user interface , an API is typically not visible to users. It is an "under the hood" portion of

4100-411: The 2.6 release, GIMP can use GEGL to perform high bit-depth color operations; because of this, less information is lost when performing color operations. When GEGL is fully integrated, GIMP will have a higher color bit depth and better non-destructive work-flow. GIMP 2.8.xx supports only 8-bit color, which is much lower than digital cameras, e.g., produce (12-bit or higher). Full support for high bit depth

4182-541: The 2006 GSoC and can be used in version 2.8.0 of GIMP, although there were three other projects that were completed and are later available in a stable version of GIMP; those projects being Vector Layers (end 2008 in 2.8 and master), and a JPEG 2000 plug-in (mid 2009 in 2.8 and master). Several of the GSoC projects were completed in 2008, but have been merged into a stable GIMP release later in 2009 to 2014 for Version 2.8.xx and 2.10.x. Some of them needed some more code work for

4264-461: The API that will be removed or not supported in the future. Client code may contain innovative or opportunistic usages that were not intended by the API designers. In other words, for a library with a significant user base, when an element becomes part of the public API, it may be used in diverse ways. On February 19, 2020, Akamai published their annual “State of the Internet” report, showcasing

4346-435: The API. The term API initially described an interface only for end-user-facing programs, known as application programs . This origin is still reflected in the name "application programming interface." Today, the term is broader, including also utility software and even hardware interfaces . The idea of the API is much older than the term itself. British computer scientists Maurice Wilkes and David Wheeler worked on

4428-502: The POSIX APIs. Microsoft has shown a strong commitment to a backward-compatible API, particularly within its Windows API (Win32) library, so older applications may run on newer versions of Windows using an executable-specific setting called "Compatibility Mode". An API differs from an application binary interface (ABI) in that an API is source code based while an ABI is binary based. For instance, POSIX provides APIs while

4510-658: The WIC stack itself underwent a major overhaul and is now free-threaded, as are all the built-in and external codecs shipping with Windows. Being free-threaded is also a requirement for new codecs targeting Windows 7. Microsoft Expression Design 's import and export capabilities are entirely based on WIC. Expression Media (now Phase One Media Pro ) with Service Pack 1 and later also supports additional raw camera formats and HD Photo (now JPEG XR ) using WIC. As of 2018, few third-party imaging applications (image editors, image organizers and image viewers) utilize WIC. FastPictureViewer ,

4592-857: The ability to preserve unrecognized metadata during editing. While working with images, it preserves high bit depth image data, up to 32 bits per channel, throughout the revamped high dynamic range image processing pipeline built into Windows Vista. Windows Imaging Component supports Windows Color System , the ICC V4-compliant color management technology in Windows Vista. By default, Windows Vista ships with JPEG , TIFF , GIF , PNG , BMP and HD Photo encoders and decoders, and an ICO decoder. Additionally, as of 2009, some camera manufacturers and 3rd-parties have released WIC codecs for proprietary raw image formats , enabling Mac-like raw image support to Windows 7 and Vista. In July 2011, this

4674-633: The annual Libre Graphics Meeting . Interaction designers from OpenUsability have also contributed to GIMP. Some blocker bugs: 6 (as of November 2023 ) on road to 3.0. The current version of GIMP works with numerous operating systems, including Linux , macOS and Windows . Many Linux distributions, such as Fedora Linux and Debian , include GIMP as a part of their desktop operating systems. GIMP began to host its own downloads after discontinuing use of SourceForge in 2013. The website later repossessed GIMP's dormant account and hosted advertising-laden versions of GIMP for Windows. In 2022, GIMP

4756-401: The application programming interface separately from other interfaces, such as the query interface. Database professionals in the 1970s observed these different interfaces could be combined; a sufficiently rich application interface could support the other interfaces as well. This observation led to APIs that supported all types of programming, not just application programming. By 1990, the API

4838-422: The development targets for 2.10.0. MacOS Beta is available with Version 2.10.4. The next stable version in the roadmap is 3.0 with a GTK3 port. 2.99-Series is the development Series to 3.0. Jehan Pages, the lead developer and maintainer of GIMP, stated that GIMP 3.0's release is tentative for May 2024 and plans to announce the release at the next Libre Graphics Meeting conference. GIMP developers meet during

4920-464: The extraction of foreground elements, such as a person or a tree in focus. The Paths Tool allows a user to create vectors (also known as Bézier curves ). Users can use paths to create complex selections, including around natural curves. They can paint (or "stroke") the paths with brushes, patterns, or various line styles. Users can name and save paths for reuse. There are many tools that can be used for editing images in GIMP. The more common tools include

5002-659: The following year, Kimball and Mattis met with Richard Stallman of the GNU Project while he visited UC Berkeley and asked if they could change General in the application's name to GNU (the name of the operating system created by Stallman), and Stallman approved. The application subsequently formed part of the GNU software collection. The first release only supported Unix systems, such as Linux , SGI IRIX and HP-UX . Since then, GIMP has been ported to other operating systems, including Microsoft Windows (1997, GIMP 1.1) and macOS . A GUI toolkit called GTK (at

5084-420: The form of different libraries that share the same programming interface. The separation of the API from its implementation can allow programs written in one language to use a library written in another. For example, because Scala and Java compile to compatible bytecode , Scala developers can take advantage of any Java API. API use can vary depending on the type of programming language involved. An API for

5166-476: The growing trend of cybercriminals targeting public API platforms at financial services worldwide. From December 2017 through November 2019, Akamai witnessed 85.42 billion credential violation attacks. About 20%, or 16.55 billion, were against hostnames defined as API endpoints. Of these, 473.5 million have targeted financial services sector organizations. API documentation describes what services an API offers and how to use those services, aiming to cover everything

5248-490: The implementation details of the modules so that users of modules need not understand the complexities inside the modules. Thus, the design of an API attempts to provide only the tools a user would expect. The design of programming interfaces represents an important part of software architecture , the organization of a complex piece of software. APIs are one of the more common ways technology companies integrate. Those that provide and use APIs are considered as being members of

5330-426: The implementation. In contrast to a user interface , which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user ) other than a computer programmer who is incorporating it into software. An API is often made up of different parts which act as tools or services that are available to

5412-596: The last couple years", and that it was "no longer a crippled alternative to Photoshop". He described GIMP's scripting as one of its strengths, but also remarked that some of Photoshop's features – such as Text, 3D commands, Adjustment Layers and History – are either less powerful or missing in GIMP. Cardinal favorably described the UFRaw converter for raw images used with GIMP, noting that it still "requires some patience to figure out how to use those more advanced capabilities". Cardinal stated that GIMP

5494-414: The main (or development) branch when the GIMP team is sure they won't damage existing functions. Sometimes this means that features that appear complete do not get merged or take months or years before they become available in GIMP. GIMP itself is released as source code. After a source code release, installers and packages are made for different operating systems by parties who might not be in contact with

5576-418: The main GIMP program. MathMap is an example of a plug-in written in C . There is support for several methods of sharpening and blurring images, including the blur and sharpen tool. The unsharp mask tool is used to sharpen an image selectively – it sharpens only those areas of an image that are sufficiently detailed. The Unsharp Mask tool is considered to give more targeted results for photographs than

5658-427: The maintainers of GIMP. The version number used in GIMP is expressed in a major-minor-micro format, with each number carrying a specific meaning: the first (major) number is incremented only for major developments (and is currently 2). The second (minor) number is incremented with each release of new features, with odd numbers reserved for in-progress development versions and even numbers assigned to stable releases;

5740-560: The master tree. Second public Development 2.9-Version was 2.9.4 with many deep improvements after initial Public Version 2.9.2. Third Public 2.9-Development version is Version 2.9.6. One of the new features is removing the 4 GB size limit of XCF file. Increase of possible threads to 64 is also an important point for modern parallel execution in actual AMD Ryzen and Intel Xeon processors. Version 2.9.8 included many bug fixes and improvements in gradients and clips. Improvements in performance and optimization beyond bug hunting were

5822-456: The new color space becomes a black-and-white image. CMYK, LAB and HSV ( hue , saturation , value ) are supported this way. Color blending can be achieved using the Blend tool, by applying a gradient to the surface of an image and using GIMP's color modes. Gradients are also integrated into tools such as the brush tool, when the user paints this way the output color slowly changes. There are

5904-614: The programmer from dealing with idiosyncrasies of the graphics display device, and to provide hardware independence if the computer or the display were replaced. The term was introduced to the field of databases by C. J. Date in a 1974 paper called The Relational and Network Approaches: Comparison of the Application Programming Interface . An API became a part of the ANSI/SPARC framework for database management systems . This framework treated

5986-416: The programmer. A program or a programmer that uses one of these parts is said to call that portion of the API. The calls that make up the API are also known as subroutines , methods, requests, or endpoints . An API specification defines these calls, meaning that it explains how to use or implement them. One purpose of APIs is to hide the internal details of how a system works, exposing only those parts

6068-442: The result to be used locally as a return value. A modification of the proxy object will also result in a corresponding modification of the remote object. Web APIs are the defined interfaces through which interactions happen between an enterprise and applications that use its assets, which also is a Service Level Agreement (SLA) to specify the functional provider and expose the service path or URL for its API users. An API approach

6150-406: The scissors select tool, which creates selections semi-automatically between areas of highly contrasting colors. GIMP also supports a quick mask mode where a user can use a brush to paint the area of a selection. Visibly this looks like a red colored overlay being added or removed. The foreground select tool is an implementation of Simple interactive object extraction (SIOX), a method used to perform

6232-452: The similar OpenJDK project. Judge William Alsup ruled in the Oracle v. Google case that APIs cannot be copyrighted in the U.S. and that a victory for Oracle would have widely expanded copyright protection to a "functional set of symbols" and allowed the copyrighting of simple software commands: To accept Oracle's claim would be to allow anyone to copyright one version of code to carry out

6314-638: The third (micro) number is incremented before and after each release (resulting in even numbers for releases, and odd numbers for development snapshots) with any bug fixes subsequently applied and released for a stable version. Previously, GIMP applied for several positions in the Google Summer of Code (GSoC). From 2006 to 2009 there have been nine GSoC projects that have been listed as successful, although not all successful projects have been merged into GIMP immediately. The healing brush and perspective clone tools and Ruby bindings were created as part of

6396-643: The time known as the GIMP ToolKit) was developed to facilitate the development of GIMP. The development of the GIMP ToolKit has been attributed to Peter Mattis becoming disenchanted with the Motif toolkit GIMP originally used. Motif was used up to GIMP 0.60. GIMP's mascot is called Wilber and was created in GIMP by Tuomas Kuosmanen, known as tigert , on 25 September 1997. Wilber received additional accessories from other GIMP developers, which can be found in

6478-455: Was defined simply as "a set of services available to a programmer for performing certain tasks" by technologist Carl Malamud . The idea of the API was expanded again with the dawn of remote procedure calls and web APIs . As computer networks became common in the 1970s and 80s, programmers wanted to call libraries located not only on their local computers, but on computers located elsewhere. These remote procedure calls were well supported by

6560-512: Was extended significantly by Microsoft itself by providing a separate Codec Pack for most current digital cameras. The Progressive Graphics File (PGF) viewer is distributed with a WIC codec. WIC supports Exchangeable Image File ( Exif ), PNG textual metadata, image file directory (IFD), IPTC Information Interchange Model (IPTC), and Extensible Metadata Platform ( XMP ) formats. In addition, WIC includes an extensible framework to support third-party metadata implementations. Metadata format support

6642-521: Was published on the Microsoft Store for Windows. Lifewire reviewed GIMP favorably in March 2019, writing that "[f]or those who have never experienced Photoshop, GIMP is simply a very powerful image manipulation program," and "[i]f you're willing to invest some time learning it, it can be a very good graphics tool." GIMP's fitness for use in professional environments is regularly reviewed; it

6724-502: Was reviewed in 2012 by Ryan Paul of Ars Technica , who noted that it made the user experience feel "more streamlined and less cluttered". Michael Burns, writing for Macworld in 2014, described the single-window interface of GIMP 2.8.10 as a "big improvement". In his review of GIMP for ExtremeTech in October 2013, David Cardinal noted that GIMP's reputation of being hard to use and lacking features has "changed dramatically over
