Diagram Designer

What Diagram Designer is

Diagram Designer is a free Windows desktop program for drawing flowcharts, UML class diagrams, illustrations, and slide shows. Its template object palette can be customized, and a spellchecker is included with downloadable dictionaries. The program imports and exports WMF, EMF, BMP, JPEG, PNG, MNG, ICO, GIF, and PCX files. Other included tools are a slide show viewer, a plotter for mathematical expressions, and a calculator with an equation solver. Its compressed drawing format is intended to keep files smaller, and integration with MeeSoft Image Analyzer supports bitmap editing and additional format support. The product page lists Windows 98, ME, 2000, XP, Vista, 7, 8, and 10. The maker says complete documentation is unavailable, but provides a collection of documents and examples. Source code can be downloaded and compiled with Borland Delphi 7. The project began in 2003 and was released as open source after its author had less time to maintain it. Diagram Designer is freeware; no free trial is listed.
