Krita: Present and Future a Look at Some of Krita’S More Recent Developments, Both in the Present 1.6 Branch and in the New 2.0 Branch What is Krita The present: Krita 1.6 The future: Krita 2 Krita: Present and Future A look at some of Krita’s more recent developments, both in the present 1.6 branch and in the new 2.0 branch Bart Coppens FOSDEM 2007 Bart Coppens Krita: Present and Future What is Krita The present: Krita 1.6 The future: Krita 2 What is Krita The present: Krita 1.6 The short road since the previous release The feature thaw of the 1.6 series The future: Krita 2 Qt4 and KDE4 KOffice2 technologies Krita design revisited Bart Coppens Krita: Present and Future What is Krita The present: Krita 1.6 The future: Krita 2 What is Krita I The KOffice painting and image editing application I Started in 1999 I Most recent release: Krita 1.6.2 on February 21, 2006 I In Swedish, Krita means ‘chalk’ or ‘crayon’. I http://www.koffice.org/krita/ Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 What happened in the last year? We released 2 major versions I Release of KOffice 1.5.0 on April 11, 2006 I Release of KOffice 1.6.0 on October 16, 2006 Some of the new features in Krita 1.6.0 include I Layer masks I Perspective grid → perspective cloning, manipulation I Curves: magnetic outline, b´ezier I Improvements in loading and handling huge files I New filters (lens correction, better blur, ...) I Tablet pressure curve editing Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Layer masks I Merge parts of two layers without destroying the original contents I Masks out a part of the regular composite operation I Paint on it like a regular greyscale layer, or like on a selection I Can prevent you from ‘drawing outside the border’ (create from selection) Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Perspective cloning I Regular cloning: does not keep into account perspective changes I Perspective cloning adds a grid that visualises ‘perspective’ I Cloning is done, but the cloned part is transformed according to the perspective grid I Unfortunately: no multiple grids can be combined (GUI would suck even more, but perhaps for Krita 2) I A good demonstration of how it works at http://www.koffice.org/krita/videos.php Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Curves I Developed during last summer’s Google Summer of Code I Has a added generic framework for drawing curves in Krita I First application: B´ezier curves I Second application: Magnetic outline Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Curves: Magnetic Outline I Create a curve following your mouse I Tries to follow edges in the neighbourhood of the mouse I Inserts nodes at regular intervals near the mouse position, tries to detect the best line between two nodes I The more contrastful and sharply outlined the area, the better the result I Hard-to-find feature: Press Ctrl for ‘Manual mode’ (move nodes, insert, remove) Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 The feature thaw of the 1.6 series I What is a feature thaw? Allowing new features to be added to a stable branch, wrongly spelled strings can be fixed. I We unfroze for 1.6.1, 1.6.2 and maybe for the upcoming 1.6.3 I Allows for long-lived branches to be more alive than otherwise. Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Levels in 1.6.1 I Began as a wishlist entry in the bugs database: http://bugs.kde.org/ show bug.cgi?id=129789 I Someone claimed it would be easy to implement this, we called his bluff I Related to Brightness/Contrast Bart Coppens Krita: Present and Future What is Krita The short road since the previous release The present: Krita 1.6 The feature thaw of the 1.6 series The future: Krita 2 Smudge in 1.6.2 I Implemented after user request I Very easy to actually write that code I ‘Simple Smudge tutorial’. First part at http://www.kdedevelopers.org/node/2594 Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited KDE4 Qt4 and KDE4 will offer some nice new technologies that KOffice2 will be able to use. I Qt4’s better threading, KDE4’s ThreadWeaver I KDE4’s Phonon: Playing of audio and video objects in KPresenter KOffice also moved some code to KDELibs: Kross, so that all KDE4 applications will be able to use this. Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Flake I Flake Shapes: everything you see is a shape I KWord → everything is a Flake shape, even pages I Krita → embedded Flake shapes (vector graphics, text) I KPresenter → everything is a Flake shape I Lightweight embeddability, compared to a full-fledged KPart like KOffice 1.x Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Pigment The KOffice color management library. Was originally Krita’s libkritacolor. I Offers some basic colorspaces hardcoded: Alpha, L*a*b* I KOffice-wide plugins for the common colorspaces: RGB, CMYK I Krita-specific plugins for natural media, HDR Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Resolution I Often requested feature I The Flake redesign was the ideal moment for adding working resolution to Krita. I ‘20cm + 15mm’? Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Layers: masks, selections and filters - The Present Our current 1.5+ design needs some reworking: I Per-layer selections, wanted or not? I Filter layers work on the entire stack below them I Masks are very static, badly integrated in the layerbox Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Layers: masks, selections and filters - The Future? There are proposals for 2.0 that could fix some of this: I Selections: ‘controversial’ issue. Selections as a special sub-layer? Global selection? I Let normal layers have filters as a per-layer stack of filters I Masks could be just some layer-filter → easy to manipulate, equal integration with filters Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited OpenRaster I Better cross-application exchange of raster data for the free software world (.kra, .xcf are too specific) I A possible solution: ‘OpenRaster’ (http://create.freedesktop.org/wiki/index.php/ General multilayered bitmap exchange format) I Very experimental stage at the moment I Support for the GIMP might be delivered partly by GEGL (http://gegl.org/) Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Dynamic brush I Proposed enhancement of the current ‘brush’ tool I Add different actions to the tablet input I Implemented as a separate paint operation Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited So where can you help? You don’t need to be able to code: I Report bugs (also for alpha and beta versions!) I Write documentation I Report about usability issues (developers often don’t see the problems with their own applications anymore) I Hard to discover features I Obvious actions not used for a feature I Contra-intuitive GUI design I Keep bugging us if we don’t fix them ;-) Bart Coppens Krita: Present and Future What is Krita Qt4 and KDE4 The present: Krita 1.6 KOffice2 technologies The future: Krita 2 Krita design revisited Questions?

The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development.

  • Rkward: a Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R
    JSS Journal of Statistical Software June 2012, Volume 49, Issue 9. http://www.jstatsoft.org/ RKWard: A Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R Stefan R¨odiger Thomas Friedrichsmeier Charit´e-Universit¨atsmedizin Berlin Ruhr-University Bochum Prasenjit Kapat Meik Michalke The Ohio State University Heinrich Heine University Dusseldorf¨ Abstract R is a free open-source implementation of the S statistical computing language and programming environment. The current status of R is a command line driven interface with no advanced cross-platform graphical user interface (GUI), but it includes tools for building such. Over the past years, proprietary and non-proprietary GUI solutions have emerged, based on internal or external tool kits, with different scopes and technological concepts. For example, Rgui.exe and Rgui.app have become the de facto GUI on the Microsoft Windows and Mac OS X platforms, respectively, for most users. In this paper we discuss RKWard which aims to be both a comprehensive GUI and an integrated devel- opment environment for R. RKWard is based on the KDE software libraries. Statistical procedures and plots are implemented using an extendable plugin architecture based on ECMAScript (JavaScript), R, and XML. RKWard provides an excellent tool to manage different types of data objects; even allowing for seamless editing of certain types. The objective of RKWard is to provide a portable and extensible R interface for both basic and advanced statistical and graphical analysis, while not compromising on flexibility and modularity of the R programming environment itself. Keywords: GUI, integrated development environment, plugin, R.
