Flake (KDE)
Flake or a Vector Shape is a programming library that is used in Calligra Suite and the KOffice 2 series. Flake provides the basic concept of a "shape". To the end user a shape appears as some piece of content such as an image or a text. A shape can be in any form (square, circle, etc.) and contain any kind of media since the Shape is responsible for drawing itself. All components of KOffice are being overhauled to use Flake as much as possible. Functionality The functionality of Flake is divided up between Shapes, which display content, and Tools, which manipulate content or the user interface. Different Shapes can be created to support different kinds of content, for example the text-shape in Calligra Words would support .txt and .odt formats while the KChart shape would just support chart-related document standard such as .odc. Shapes are packaged with a set of tools to manipulate that kind of content and UI elements that expose the functionality to the user. This provides an ...

Programming Library
In computer science, a library is a collection of non-volatile resources used by computer programs, often for software development. These may include configuration data, documentation, help data, message templates, pre-written code and subroutines, classes, values or type specifications. In IBM's OS/360 and its successors they are referred to as partitioned data sets. A library is also a collection of implementations of behavior, written in terms of a language, that has a well-defined interface by which the behavior is invoked. For instance, people who want to write a higher-level program can use a library to make system calls instead of implementing those system calls over and over again. In addition, the behavior is provided for reuse by multiple independent programs. A program invokes the library-provided behavior via a mechanism of the language. For example, in a simple imperative language such as C, the behavior in a library is invoked by using C's normal functi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligra Suite
Calligra Suite is a graphic art and office suite by KDE. It is available for desktop PCs, tablet computers, and smartphones. It contains applications for word processing, spreadsheets, presentation, databases, vector graphics, and digital painting. Calligra uses the OpenDocument format as its default file format for most applications and can import other formats, such as Microsoft Office formats. Calligra relies on KDE technology and is often used in combination with KDE Plasma Workspaces. Supported systems Desktops Calligra's main platform is desktop PCs running Linux, FreeBSD, macOS, and Windows, of which Linux is the best supported system. On desktop systems, the whole range of features is available. Smartphones and tablets , Calligra's efforts to create touchscreen-friendly versions are centered on reusable Qt Quick components. For smartphone-like formfactors 3rd party documents viewers Coffice for Android and Sailfish Office for Sailfish OS are available that mak ...

KOffice
KOffice is a free and open source office and graphics suite developed by KDE for Unix-like and Windows systems. KOffice contains a word processor (KWord), a spreadsheet ( KSpread), a presentation program (KPresenter), and a number of other components that varied over the course of its development. KOffice was superseded by Calligra Suite in KDE. The KDE3 version is maintained by the Trinity Desktop project. After development began in 1997, two major stable releases of KOffice were published: Version 1.0 in 2000 and 2.0 in 2009. Following internal conflicts, the majority of KOffice developers split off in 2010 – resulting in the creation of Calligra Suite. Two years later, in September 2012, the KOffice.org website went offline. It now redirects to Calligra.org. History First generation Initial work on KOffice development began in 1997, by Reginald Stadlbauer with KPresenter, followed by KWord in 1998. In 1999, KOffice was cited in testimony in the ''United States v. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligra Words
Calligra Words is a word processor, which is part of Calligra Suite and developed by KDE as free software. History When the Calligra Suite was formed, unlike the other Calligra applications Words was not a continuation of the corresponding KOffice application – KWord. The Words was largely written from scratch – in May 2011 a completely new layout engine was announced. The first release was made available on , using the version number 2.4 to match the rest of Calligra Suite. Reception Initial reception of Calligra Words shortly after the 2.4 release was mixed. While Linux Pro Magazine Online's Bruce Byfield wrote “Calligra needed an impressive first release. Perhaps surprisingly, and to the development team’s credit, it has managed one in 2.4.”, he also noted that “Words in particular is still lacking features”. He concluded that Calligra is “worth keeping an eye on”. On the other hand, Calligra Words became the default word processor in Kubuntu 12.04 ...

KChart
Calligra Sheets (formerly ''KSpread'' and ''Calligra Tables'') is a free software spreadsheet application that is part of Calligra Suite, an integrated graphic art and office suite developed by KDE. Among Sheets’ features are multiple sheets per document, assorted formatting possibilities, support for more than 300 built-in functions, templates, chart, spell-check, hyperlinks, data sorting and scripting with Python, Ruby and JavaScript. Sheets’ native file format has been OpenDocument since version two and previously used its own XML format, compressed with ZIP. Sheets also has the ability to import several spreadsheet formats, including XLS (Microsoft Excel), Applix Spreadsheet, Quattro Pro, CSV, dBase, Gnumeric, SXC (OpenOffice.org XML), Kexi and TXT. It supports export of OpenDocument Spreadsheet, SXC, Tables document, CSV, HTML, Gnumeric, TeX and TXT. Sheets does not support export of XLS. KChart KChart is the charting tool of Calligra Suite. The plug-in is relative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MusicXML
MusicXML is an XML-based file format for representing Western musical notation. The format iopen fully documented, and can be freely used under the W3C Community Final Specification Agreement. History MusicXML was invented by Michael Good and initially developed by Recordare LLC. It derived several key concepts from existing academic formats (such as Walter Hewlett's ASCII-based MuseData and David Huron's Humdrum). It is designed for the interchange of scores, particularly between different scorewriters. MusicXML development was managed by MakeMusic following the company's acquisition of Recordare in 2011. MusicXML development was transferred to the W3C Music Notation Community Group in July 2015. Version 1.0 was released in January 2004. Version 1.1 was released in May 2005 with improved formatting support. Version 2.0 was released in June 2007 and included a standard compressed format. All of these versions were defined by a series of document type definitions (DTDs). An XML Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music Notation
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm or otherwise expressive content. Exact definitions of music vary considerably around the world, though it is an aspect of all human societies, a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice. In some musical contexts, a performance or composition may be to some extent improvised. For instance, in Hindustani classical music, the performer plays spontaneously while following a partially defined structure and using characteristic motifs. In modal jazz ...

Anti-alias
In digital signal processing, spatial anti-aliasing is a technique for minimizing the distortion artifacts (aliasing) when representing a high-resolution image at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other applications. Anti-aliasing means removing signal components that have a higher frequency than is able to be properly resolved by the recording (or sampling) device. This removal is done before (re)sampling at a lower resolution. When sampling is performed without removing this part of the signal, it causes undesirable artifacts such as black-and-white noise. In signal acquisition and audio, anti-aliasing is often done using an analog anti-aliasing filter to remove the out-of-band component of the input signal prior to sampling with an analog-to-digital converter. In digital photography, optical anti-aliasing filters made of birefringent materials smooth the signal in the spatial optical domain. The anti ...

KDE Frameworks
KDE Frameworks is a collection of libraries and software frameworks readily available to any Qt-based software stacks or applications on multiple operating systems. Featuring frequently needed functionality solutions like hardware integration, file format support, additional graphical control elements, plotting functions, and spell checking, the collection serves as technological foundation for KDE Plasma 5 and KDE Gear distributed under the GNU Lesser General Public License (LGPL). Overview Current KDE Frameworks are based on Qt 5, which enables a more widespread use of QML, a simpler JavaScript-based declarative programming language, for the design of user interfaces. The graphics rendering engine used by QML allows for more fluid user interfaces across different devices. Since the split of the KDE Software Compilation into KDE Frameworks 5, KDE Plasma 5 and KDE Applications, each sub-project can pick its own development pace. KDE Frameworks are released on a monthly basis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Libraries
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...
