sK1 is an open-source illustration program for the Linux platform that can be used as a substitute for professional proprietary software like CorelDRAW or Adobe Illustrator. Unique project features are CorelDRAW formats importers, tabbed multidocument interface, Cairo-based engine, and color management. The program was put on feature freeze since 2010, and development switched to its successor, PrintDesign.

History[edit]

A small team led by Igor Novikov started the project in 2003, based on the existing open source vector graphics editor Skencil. It was based on the Skencil 0.6.x series which used Tk widgets for a GUI. This version was dropped by the main Skencil developers who have since started developing a new branch of the program based on GTK+ (although this version remains immature compared to the 0.6.x series). sK1 has therefore become a fork. Although an attempt was made to unify the project with Skencil, it failed.

In 2007 the sK1 team reverse-engineered the CDR format.[2] The results and the first working snapshot of the CDR importer were presented at the Libre Graphics Meeting 2007 conference taking place in May 2007 in Montreal (Canada).[3] Later on the team parsed the structure of other Corel formats with the help of CDR Explorer.[4] As of 2008, the sK1 project claims to have the best import support for CorelDRAW file formats among open source software programs.

Target audience[edit]

Since the project was started by a small team of Ukrainian professionals in prepress, it was unambiguously focused on full support for PostScript, PDF, CMYK color model and color management at the expense of developing some advanced functions for illustrators[citation needed]. Informally the project is positioned as a free open source alternative to the commercial CorelDRAW[citation needed].

Side (friendly) projects[edit]

  • UniConvertor. It is an application for conversion of files from one vector format into another one. In fact it is a part of sK1, rewritten as a standalone code and being developed by the same team. UniConvertor is also used by Inkscape for opening CorelDRAW, WMF and Sketch/Skencil files.[5][6][7] Within a framework of Google Summer of Code 2008 the support of UniConvertor is being prepared for Scribus.
  • CDR Explorer. It is a program that simplifies the reverse-engineering of Corel DRAW formats.
  • pymfvu. It is a program for WMF/EMF files preview and export to SVG. At project development a comprehensive report on WMF support by various open source and closed applications was made. It is discontinued now.
  • LinCutter. It is an application for interactive work with cutting plotters (PLT format).

Awards[edit]

  • In 2007 the project was awarded the second place in the Trophées du Libre open source project contest in the "Multimedia and games" category.[8]
  • In 2009 the project was awarded the second place in the contest "The best free project of Russia", conducted by Linux Format magazine. Among the group projects.
