About formats

CDR is the native file format of CorelDRAW, a vector graphics editor developed by Corel Corporation and first released for Windows in January 1989. The format stores complex vector illustrations using a RIFF-based container structure (Resource Interchange File Format), organizing page content, object properties, color palettes, and metadata across multiple data chunks. CDR supports a comprehensive range of vector objects including Bezier curves, rectangles, ellipses, artistic text, paragraph text, powerclips, drop shadows, transparency lenses, contours, blends, envelopes, and multi-page document layouts. Each new major release of CorelDRAW introduces an updated CDR version, sometimes adding features that are not backward-compatible with older software versions. One notable advantage is rich feature density — CDR files can contain extremely complex artwork combining vector objects with embedded bitmap effects, multi-point color fills, and mesh fills, all within a single native document. The format's strong presence in certain professional niches is another practical strength: sign-making, screen printing, engraving, and vinyl cutting industries widely standardize on CDR as their primary working format, with direct output to cutting plotters and production equipment. While CorelDRAW originated as a Windows application and CDR remains most fully supported on that platform, import support exists in competing editors including Inkscape, Adobe Illustrator, and LibreOffice Draw.

SK1 is the native file format of the sK1 project), an open-source vector graphics editor and conversion engine started by Igor Novikov in 2003 as a successor to Bernhard Herzog's Skencil. The format evolved from the original SK format, extending its capabilities while maintaining the text-based, Python-readable syntax for describing vector documents. SK1 files encode complete document structures including multiple pages, layers, guidelines, and a full hierarchy of graphic objects — Bezier paths, rectangles, circles, polygons, text blocks, and embedded raster images — with attributes for fills (solid, gradient, pattern, hatching), strokes, and transformations. The sK1 project distinguished itself by focusing on prepress and professional print production features, adding CMYK color management, ICC color profiles, spot color support, and PDF/PostScript output — capabilities unusual in open-source vector editors. One advantage is professional color handling — sK1's CMYK workflows and color management make it one of the few open-source tools suitable for print-ready vector production. The project's companion tool, UniConvertor, leverages the SK1 format as an intermediate representation for converting between numerous vector formats (CDR, CMX, WMF, EMF, SVG, and others), giving SK1 significance beyond the editor itself as a universal interchange format. The text-based file structure preserves the readability and scriptability advantages inherited from Skencil's original SK format.
