2014-06-30: WebODF 0.5 gains text editor: edit OpenDocument format files in webpages and webapps

KO GmbH and the developers of WebODF today released WebODF 0.5. After a long period of hard work, this new version features editing of OpenDocument Text files. It also contains lots of display improvements. WebODF still uses only HTML, CSS and JavaScript without any need for a special server software.

WebODF 0.5 adds an API for implementing editors for OpenDocument Format. This allows for custom extensions and adaptions to different backends and UIs. In this version there is built-in support for enabling annotations, editing of hyperlinks and predefined paragraph styles, as well as direct formatting of text and paragraphs, with more to come.

WebODF 0.5 is accompanied by the simple to use JavaScript component Wodo.TextEditor, which is built on top of WebODF 0.5. It makes it easy to add an ODT editor element e.g. to your webpage in a few lines of JavaScript.

With the 0.5 release out, future WebODF releases will be done approximately once every month to get improvements quickly into your hands. Support for realtime-collaborative editing has already been part of special WebODF variants for the document editor ownCloud Documents, added in version 6 of the cloudstorage solution ownCloud. It is currently worked on more and will be officially part of WebODF in the upcoming weeks.

Try the demos. Download the webodf.js library, the Wodo.TextEditor component and more, and enhance your webpages and HTML5 apps with viewing and editing support for ODF files. Contact KO GmbH for commercial support.

2013-10-24: KO GmbH Introduces Collaborative Document Editing for ownCloud 6 Community Edition

KO GmbH (KO) announced today collaborative editing of office documents with ownCloud 6 Community Edition, done by integrating the WebODF web document technology into ownCloud. ownCloud provides authentication and access control of documents while WebODF provides viewing and editing of the documents.

KO is the company behind WebODF, a document viewer and editor that runs completely in a web browser. WebODF can be used stand-alone in websites where only document viewing is needed. You can add these capabilities to websites by adding a very short javascript snippet. WebODF can also be packaged into HTML5 applications that work on any mobile platform. For collaborative editing a server component is required. WebODF is available under the Affero GPL and under a commercial license.

With Collaborative Document Editing, ownCloud users can now work together on the same document at the same time. This server component and access control makes ownCloud into a hub not only for file management but also for document management.

"ownCloud and the WebODF technology fit perfectly into each other," said Frank Karlitschek, CTO and co-founder of ownCloud Inc. "ownCloud provides the server framework and WebODF provides the document manipulation. Together they further the ownCloud vision of a self-controlled free and open source cloud."

2013-09-11: KO GmbH presents Krita Gemini

KO GmbH have created a new version of the acclaimed painting application Krita: Krita Gemini. Krita Gemini is an innovative and fun application for use with transformable ultrabooks such as the Dell XPS 12. Start in tablet mode or in desktop mode, Krita Gemini will switch when you transform your ultrabook to a tablet or the other way around!

KO GmbH worked closely with Intel to develop this innovative technology. Intel's testing lab commented "Krita Gemini is a brilliant example of how developers should utilise the option of a convertible device by using both tablet and desktop mode. The switching between the two modes works seamlessly, allowing the user to have the freedom to choose how they would like to use their device and Krita Gemini adjusts itself to their needs perfectly."

Krita Gemini features the unique switchable interface, optimized touch-screen integration both in desktop and in sketch mode and support for Wacom digitizers, also in both modes. Take your ultrabook, go out and create, come home and present your work!

2013-08-30: KO GmbH and NLnet Foundation Announce Viewer.js

KO GmbH and the NLnet Foundation today announce Viewer.js, a JavaScript based viewing application for cloud services, websites and mobile applications.

Viewer.js combines two technologies: WebODF from KO GmbH for OpenDocument based text documents, spreadsheets and presentations and PDF.js from the Mozilla foundation for PDF documents into one viewer application. The only HTML that is needed to show this advanced viewer with an embedded document in a web page is one single link. This makes it extremely simple to use and very well suited for cloud-based services where documents of any kind are involved.

With Viewer.js there is no more need to install specialized viewer applications on your user's computers. This reduces maintenance costs as well as increases security by eliminating a source of viruses and other malware.

Viewer.js is open source software licensed under the AGPL v3. You can fork the project on Github and join our development team. We are interested in supporting more formats such as other office documents and ebooks.

2013-04-22: KO GmbH Announces Support and Maintenance for Krita: Krita Studio

KO GmbH announces extensive support services for the award-winning professional paint application Krita. Krita is an advanced paint application with a large set of professional paint tools and which can handle extremely large images effortlessly. This makes it well suited for special effects work in the movie industry.

Krita has already been used in several Hollywood block buster movies like G.I. Joe 2 by VFX leaders such as Digital Domain. Krita has been used for many different tasks including concept art, matte painting and rotoscopy.

Until now Krita has lacked a structured support offering, something that KO GmbH, which employs several of the lead developers of Krita, sees as an opportunity. Simon Legrand, currently 3D generalist at Double Negative in London says: "It's a testament to the quality and productivity of Krita that I have been able to use it to such an extent already before the availability of company support for it." Boudewijn Rempt, maintainer of Krita and CTO at KO GmbH adds: "There is a very lively community around Krita and we are always working with the needs of our users before our eyes."

KO GmbH, the company which brought the Calligra application suite to Windows, Android, Maemo and MeeGo, is pleased to announce that they will start working on creating a new Windows version of the acclaimed digital painting application Krita, with funding from Intel.

The application will be called Krita Sketch. Krita Sketch will integrate with all the new touch facilities on Ultrabooks and upcoming Intel-based tablets and give new possibilities to creative artists everywhere.

"Touch", explains Krita maintainer Boudewijn Rempt, "has been consistently underused in painting applications. Let's go beyond pinch-to-zoom. Let's make it possible to smudge, smear, paint, transform and warp right in your image with your fingers. Let's bring a new level of control, of feeling to digital art. This will be fun -- but not just fun, we aim to give a real boost your productivity as an artist."

Krita already has a lively community of professional and amateur artists, as well as a dedicated developer community. In the past two years, Krita made the jump to readiness for professional artists on Linux; with this project, it will make that step on Windows as well.

Krita Sketch will be developed together with the Krita community in the Krita source repository. Official installers of the new application will be available though Intel's AppUp application store.
