sK1 illustration program sK1 is an open-source illustration program that can substitute professional proprietary software like Corel Draw or Adobe Illustrator*. Currently GNU/Linux is our main development platform, but porting on Win32 and MacOS X desktops has been scheduled. sK1 supports professional publishing features, such as CMYK color, separations, ICC color management and press-ready PDF output. # UniConvertor UniConvertor is a universal vector graphics translator. It is a command line tool which uses sK1 object model to convert one file format to another. The project is a multiplatform software and can be compiled under GNU/Linux (and other UNIX-like systems), MacOS X and Win32/64 operation systems. # CDR Explorer CDR Explorer is a research tool for CorelDraw file formats. It was used to create a CDR import filter for sK1 Editor and UniConvertor. This tool is written on Python and works under GNU/Linux, MacOS X and Win32. # WMF format parser (pymfvu) pymfvu is a small research project. This project was started to prepare new WMF/EMF filter for sK1 and Uniconvertor. The pymfvu program can open and render both Windows Metafile and Enchanced Metafile files.
