The history of sK1
sK1 editor is a fork of Sketch 0.6.15. It was a result of day-by-day patching of Sketch in an attempt to migrate our printing firm to free software. Sketch development seemed to be stalled already, so when the Sketch/Skencil maintainers decided to switch to Gtk+ widgetset, we were forced to fork. We migrated to Ttk (former Tile widgetset), added CMYK support, color management, and Cairo-based engine.
The "sK1" name derives from "Sketch/Skencil" and second large K character means that application layout is similar with KDE applications althouh sK1 has no dependencies on KDE libraries. Number 1 means our goal - stable application compartible with CorelDraw and Adobe Illustrator and suitable for regular jobs in prepress.
In December 2006 we started to investigate CorelDraw CDR file format. The CDR import filter was made in weeks and presented together with sK1 on LGM2007 in Montreal, Quebec.
Unfortunately Tk widgetset had no further development. So we decided to change basic widgetset for sK1. At the same time we needed to remove X11 dependencies in document model for multiplatforming. Therefore in 2010 year we announced the project will be reloaded.
We spent two year for prototyping and R&D. Finally wxwidgets was selected as a best choice for mutiplatform application. Also we redesigned document model completely. By this way sK1 2.0 has been written from scratch.
