Kabeja is a Java library for parsing, processing and converting Autodesk's DXF format. You can use Kabeja from the CommandLine or embed into your application. All parsed data are accessible with the DOM-like API. The processing system allows you to process, filter (e.g. XSLT) and convert DXF drafts to different output formats (SVG, JPEG, PNG, TIFF, PDF, XML).
