Poppler (software)
Poppler is a free software utility library for rendering Portable Document Format (PDF) documents. Its development is supported by freedesktop.org. It is commonly used on Linux systems, and is used by the PDF viewers of the open source GNOME and KDE desktop environments. The project was started by Kristian Høgsberg with two goals: to provide PDF rendering functionality as a shared library, to centralize maintenance effort and to go beyond the goals of Xpdf, and to integrate with functionality provided by modern operating systems. As of the version 0.18 release in 2011, the poppler library represents a complete implementation of ISO 32000-1, the PDF format standard, and is the first major free PDF library to support its forms (only Acroforms but not full XFA forms) and annotations features. Poppler is a fork of Xpdf-3.0, a PDF file viewer developed by Derek Noonburg of Glyph and Cog, LLC. The name ''Poppler'' comes from the animated series ''Futurama'' episode "The Problem w ...

Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...

Motif (software)
In computing, Motif refers to both a graphical user interface (GUI) specification and the widget toolkit for building applications that follow that specification under the X Window System on Unix and Unix-like operating systems. The Motif look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements. Motif is the toolkit for the Common Desktop Environment and IRIX Interactive Desktop, thus it was the standard widget toolkit for Unix. Closely related to Motif is the Motif Window Manager (MWM). After many years as proprietary software, Motif was released in 2012, as free software under the GNU Lesser General Public License (LGPL-2.1-or-later). History Motif was created by the Open Software Foundation (OSF) to be a standard graphical user interface for Unix platforms. Rather than create a new interface from scratch, OSF opened a Request For Technology (RFT) in 1988 to solicit existing technologies ...

TeXworks
TeXworks is free and open-source application software, available for Windows, Linux and macOS. It is a Qt-based graphical user interface to the TeX typesetting system and its LaTeX, ConTeXt, and XeTeX extensions. TeXworks is targeted at direct generation of PDF output. It has a built-in PDF viewer using the poppler library; the viewer has auto-refresh capability, and also features SyncTeX support (which allows the user to synchronize the PDF viewer position with the source, and ''vice versa'' with a single click). The developer of TeXworks is Jonathan Kew (who also developed XeTeX), who deliberately modelled TeXworks on Richard Koch’s award-winning TeXShop software for macOS to lower the entry barrier to the TeX world for those using desktop operating systems other than macOS. Kew argued against complex user interfaces like that of TeXnicCenter or Kile, which he described as intimidating for new users. TeXworks requires a TeX installation: TeX Live, MiKTeX, or MacTeX.

TeXstudio
TeXstudio is a cross-platform open-source LaTeX editor. Its features include an interactive spelling checker, code folding, and syntax highlighting. It does not provide LaTeX itself – the user must choose a TeX distribution and install it first. Originally called TexMakerX, TeXstudio was started as a fork of Texmaker that tried to extend it with additional features while keeping its look and feel. Features TeXstudio's features include: * Auto-completion (also of newly defined custom LaTeX commands) * Scripting support * Assistants for images, tables, formulas (assistants offer GUI for visual and user-friendly creation of structures with complex code) * Drag and drop support for images * Template system * Syntax highlighting * Spellchecker * Integrated PDF viewer * Live-updating inline preview for formulas and code segments * SVN support * Integration with the BibTeX and BibLaTeX bibliographies managers * Export into HTML * Document lexical analysis (e.g. word count, word fr ...

Pdftotext
pdftotext is an open-source command-line utility for converting PDF files to plain text files—i.e. extracting text data from PDF-encapsulated files. It is freely available and included by default with many Linux distributions, and is also available for Windows as part of the Xpdf Windows port. Such text extraction is complicated as PDF files are internally built on page drawing primitives, meaning the boundaries between words and paragraphs often must be inferred based on their position on the page. pdftotext is part of the Xpdf software suite. Poppler, which is derived from Xpdf, also includes an implementation of pdftotext. On most Linux distributions, pdftotext is included as part of the poppler-utils package. See also * List of PDF software This is a list of links to articles on software used to manage Portable Document Format (PDF) documents. The distinction between the various functions is not entirely clear-cut; for example, some viewers allow adding of annotati ...

Qt (toolkit)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a '' widget toolki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okular
Okular is a multiplatform document viewer developed by the KDE community and based on Qt and KDE Frameworks libraries. It is distributed as part of the KDE Applications bundle. Its origins are from KPDF and it replaces KPDF, KGhostView, KFax, KFaxview and KDVI in KDE 4. Its functionality can be embedded in other applications. History Okular was started for the Google Summer of Code of 2005 by Piotr Szymański. Okular was identified as a success story of the 2007 Season of Usability. In this season the Okular toolbar mockup was created based on an analysis of other popular document viewers and a usage survey. When it was ported to Qt 5 in December 2016, the version numbering jumped from 0.26 to 1.0. Since September 2019, Okular is available in the Windows Store. In December 2020, the software versioning scheme was changed from sequence-based identifier to CalVer. In February 2022, Okular was awarded the Blue Angel environmental label award by the German government for sust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LibreOffice
LibreOffice () is a free and open-source productivity software, office productivity software suite, a project of The Document Foundation (TDF). It was fork (software development), forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice. The LibreOffice suite consists of programs for word processing, creating and editing of spreadsheets, slideshows, diagrams and drawings, working with databases, and composing mathematical formulae. It is available in 115 languages. TDF doesn't provide support for LibreOffice, but enterprised-focused editions are available from companies in the ecosystem. LibreOffice uses the OpenDocument standard as its native file format, but supports formats of most other major office suites, including Microsoft Office, through a variety of import and export filters. LibreOffice is available for a variety of computing platforms, with official support for Microsoft Windows, macOS and Linux and community builds for many other platfo ...

Inkscape
Inkscape is a free and open-source vector graphics editor used to create vector images, primarily in Scalable Vector Graphics (SVG) format. Other formats can be imported and exported. Inkscape can render primitive vector shapes (e.g. rectangles, ellipses, polygons, arcs, spirals, stars and 3D boxes) and text. These objects may be filled with solid colors, patterns, radial or linear color gradients and their borders may be stroked, both with adjustable transparency. Embedding and optional tracing of raster graphics is also supported, enabling the editor to create vector graphics from photos and other raster sources. Created shapes can be further manipulated with transformations, such as moving, rotating, scaling and skewing. History Inkscape began in 2003 as a code fork of the Sodipodi project. Sodipodi, developed since 1999, was itself based on Raph Levien's Gill (GNOME Illustration Application). One of the main priorities of the Inkscape project was interface consistency an ...

Evince
Evince (), also known as GNOME Document Viewer, is a free and open source document viewer supporting many document file formats including PDF, PostScript, DjVu, TIFF, XPS and DVI. It is designed for the GNOME desktop environment. The developers of Evince intended to replace the multiple GNOME document viewers with a single and simple application. The Evince motto sums up the project aim: "Simply a Document Viewer". GNOME releases have included Evince since GNOME 2.12 (September 2005). Evince's code is written mainly in C, with a small part (specifically, the interface with Poppler) written in C++. Many Linux distributions – including Ubuntu, Fedora Linux and Linux Mint – include Evince as the default document viewer. Evince is free and open-source software subject to the requirements of the GNU General Public License version 2 or later. The Evince FAQ highlights the meaning of the word "Evince" as "to show or express something clearly". History Evince began as a re ...
