Calligra Stage (formerly KPresenter) is a free presentation program that is part of the Calligra Suite, an integrated office suite developed by KDE.
Calligra Stage's native export format is OpenDocument. [1] Stage is able to load presentation documents from Microsoft PowerPoint, LibreOffice Impress and OpenOffice Impress. [2]
In 2014, development of Calligra Gemini with official support for Windows was announced. [3] [4]
Reginald Stadlbauer began development of KPresenter in 1997. [5] [6] The first official release of the KOffice suite was on October 23, 2000 when it was released as part of K Desktop Environment 2.0. [7] Versions 1.1 followed in 2001, [8] 1.2 in 2002, [9] 1.3 in 2004, [10] 1.4 in 2005, [11] and 1.5 [12] and 1.6 both in 2006. [13]
KOffice underwent a major transition as part of the release of KDE Software Compilation 4 (SC4). Coinciding with the work on SC4, the KOffice team prepared a major new release – KOffice 2.0 – which used the new KDE Platform 4 libraries. Although version 2.0 was released in 2009, the release was labeled as a “platform release” which was recommended only for testers and developers, rather than production use, since the release was missing key features and applications from the previous stable release series. [14]
This continued with version 2.1 in November, 2009. Regular end-users requiring a stable environment were still recommended by developers to use the stable 1.6 release series. [15] This version was also ported to Haiku [16] but the port was later not updated for newer KOffice versions.
In May 2010, version 2.2.0 was released and brought many new features and bugfixes. Kexi was integrated again. Kivio has not yet been migrated. A new framework for effects on shapes and a new import filters for the Microsoft Office Open XML formats that are used in MS Office 2007 and later got added. [17]
In mid-2010, following disagreements between KWord’s maintainer Thomas Zander and the other core developers, [18] [19] [20] KPresenter was renamed Calligra Stage. [21] The KWord maintainer forked the KPresenter presentation tool to create KOffice Showcase.
KOffice 2.3, released 31 December 2010, [22] along with subsequent bugfix releases (2.3.1–2.3.3 [23] ) was still a collaborative effort of both the KOffice and Calligra development teams. [18] [24]
KOffice Showcase 2.4 never materialized in release form. As of 2014 [update] KOffice was declared unmaintained by KDE. [25] [26]
On 18 May 2011 the Calligra team began releasing monthly snapshots while preparing for the release of Calligra 2.4.
The first version of the Calligra Suite for Windows was released on 21 December 2011. The package is labeled as “highly experimental” and “not yet suitable for daily use”. [27]
The Calligra team originally scheduled to release the final 2.4 version in January 2012 [28] but problems in the undo/redo feature of Words and Stage required a partial rewrite and caused a delay. [29] Calligra 2.4 was released on 11 April 2012. [30]
Calligra 2.4 launched with two mobile-oriented user interfaces: Calligra Mobile [31] and Calligra Active. Calligra Mobile's development was initiated in summer 2009 and first shown during Akademy / Desktop Summit 2009 by KO GmbH as a simple port of KOffice to Maemo. Later Nokia hired KO to assist them with a full-fledged mobile version, including a touchscreen-friendly user interface which was presented by Nokia during Maemo Conference in October 2009. [32] The first alpha version was made available in January 2010. [33] Along with the launch of the Nokia N9 smartphone, Nokia released its own Poppler and Calligra-based office document viewer under GPL. [34] [35]
Calligra Active was launched in 2011 after the Plasma Active initiative to provide a document viewer similar to Calligra Mobile but for tablet computers. [36]
Jolla continued Nokia's efforts on a smartphone version. In 2013 Jolla launched Sailfish Office. [37] Sailfish Office reuses the Qt Quick components from Calligra Active. [3]
In September 2013 a merger of Krita and Krita Sketch, named Krita Gemini, was launched on Windows 8.1. Development was funded by Intel to promote 2in1 convertible notebooks. [38] [39] [40]
In April 2014 Intel and KO GmbH extended the promotion deal to Gemini versions of Stage and Words. [4] On 28 August 2014 the first snapshot of Calligra Gemini was released by KO GmbH for Windows. [41] [42] On 21 November 2014 KDE announced that Calligra Gemini would officially be released as part of Calligra 2.9. [3] As with Krita, this Gemini release adds a touchscreen interface to Words and Stage and users can switch between desktop and touch mode at runtime. Calligra Gemini is a continuation of Calligra Active and Sailfish Office developments but with added editing capabilities. [3] On 19 October 2014 a Linux version was presented. [4]
KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that enable collaborative work on its projects. Its products include the Plasma Desktop, KDE Frameworks, and a range of applications such as Kate, digiKam, and Krita. Some KDE applications are cross-platform and can run on Unix and Unix-like operating systems, Microsoft Windows, and Android.
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 Words is a word processor, which is part of Calligra Suite and developed by KDE as free software.
Qt is a cross-platform application development framework 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.
Kexi is a visual database applications creator tool by KDE, designed to fill the gap between spreadsheets and database solutions requiring more sophisticated development. Kexi can be used for designing and implementing databases, data inserting and processing, and performing queries. It is developed within the Calligra project but is released separately.
Krita is a free and open-source raster graphics editor designed primarily for digital art and 2D animation. Originally created for Linux, the software also runs on Windows, macOS, Haiku, Android, and ChromeOS, and features an OpenGL-accelerated canvas, colour management support, an advanced brush engine, non-destructive layers and masks, group-based layer management, vector artwork support, and switchable customisation profiles.
Maemo is a Linux-based software platform originally developed by Nokia, now developed by the community, for smartphones and Internet tablets. The platform comprises both the Maemo operating system and SDK. Maemo played a key role in Nokia's failed strategy to compete with Apple and Android; the only retail devices that shipped with Maemo were the Nokia Internet tablet line released in 2005 and the Nokia N900 smartphone in 2009.
Kugar is a discontinued tool for generating business quality reports for KOffice. The reports can be viewed and printed. It includes a standalone report viewer and a KParts report viewer. The latter means that any K Desktop Environment 3 application can embed the report viewing functionality and that reports can be viewed using the Konqueror browser.
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: Plasma Desktop for traditional desktop PCs and notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
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 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.
K Desktop Environment 2 was the second series of releases of the K Desktop Environment. There were three major releases in this series.
Calligra Plan is a project management application that can create Gantt-style charts and is part of Calligra Suite – formerly included with KOffice.
MeeGo is a discontinued Linux distribution hosted by the Linux Foundation, using source code from the operating systems Moblin and Maemo. MeeGo was primarily targeted at mobile devices and information appliances in the consumer electronics market. It was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems.
KOffice was 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.
KWord is a deprecated word processor and a desktop publishing application, part of the KOffice suite. It has been obsoleted by Calligra Words of the Calligra Suite.
The Nokia N9 is a flagship smartphone developed by Nokia, running on the Linux-based MeeGo mobile operating system. Announced in June 2011 and released in September, it was the first and only device from Nokia with MeeGo, partly because of the company's partnership with Microsoft announced that year. It was initially released in three colors: black, cyan and magenta, before a white version was announced at Nokia World 2011.
Jolla Oy is a Finnish technology company; vendor and developer of Sailfish OS. Headquartered in Tampere, Finland, Jolla has its own research and development offices in Helsinki, Tampere and Cyberport, Hong Kong. Jolla was founded in 2011 by former Nokia staff of the MeeGo project team to use the MeeGo opportunities and its "endless possibilities".
The KDE Gear is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule.
KDE Projects are projects maintained by the KDE community, a group of people developing and advocating free software for everyday use, for example KDE Plasma and KDE Frameworks or applications such as Amarok, Krita or Digikam. There are also non-coding projects like designing the Breeze desktop theme and iconset, which is coordinated by KDE's Visual Design Group. Even non-Qt applications like GCompris, which started as a GTK-based application, or web-based projects like WikiToLearn are officially part of KDE.
