这是linux版本的，3.6版，功能方面，yEd 支持自动布局，分组管理等等，支持 UML。可以根据绘制的 UML 图生成 JAVA 代码，可以直接导出为 Gif、PNG、Jpeg、Pdf、Html 图像地图文件等。通过试用，感觉另外一个比较重要的功能是它可以支持外部添加的图形，这使得这款小巧的软件也具备了扩展图形库的可能。-This is the linux version, 3.6, function, yEd supports automatic layout, group management, etc., support the UML. Draw the UML diagram can generate JAVA code that can be directly exported to Gif, PNG, Jpeg, Pdf, Html image map files. Through the trial, I feel another more important function is to add that it can support external graphics, which makes this compact software graphics library with an extension possible.
