CDR to DJVU Converter

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.
