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?
