The Enhanced MetaFile format (EMF) is the native vector graphics file format on Windows. Qt is a cross-platform application development framework, widely used for the development of GUI programs. Although it provides tools for almost every aspect of software development, Qt doesn't include a straightforward solution for the export of 2D graphics to the EMF format. EmfEngine covers this lack and enables Qt-based applications to easily export graphics to the Enhanced Metafile format.
Asciidia generates bitmap or vector files from simple ASCII diagrams. It was inspired by ditaa but has a plugin based architecture, which allows it to draw specialized diagrams. Currently-supported diagram types are simple ASCII diagrams and directory trees. Asciidia can directly output SVG and MVG. For additional file formats, an ImageMagick installation is required.
