| 摘 要： | 为了提高科技文档中几何作图的效率,在科技文档字处理软件ScienceWord中实现了一种基于约束的平面几何作图系统.为了构建基于约束的作图系统,对约束的相关理论作了研究,讨论了该作图系统的总体设计框架和构建约束作图系统的一般步骤,介绍了系统中建立元素之间约束的用户界面设计.由于系统充分考虑了图形元素之间的几何关系,用户不必求助于别的软件就能在科技文档中高效地绘制出各种复杂的几何图形.

| Abstract: | In order to improve the efficiency of geometric figure drawing in scientific document,a plane geometric construction system based on constraints is implemented in ScienceWord,which is a scientific document processing software.The theory of constraints is introduced firstly,and then the overall design and the way to build the drawing system based on constraints is discussed in details.A convenient user interface of thesystem to establishconstraints between graphical elements is also introduced.Becausethe drawing system takes advantage of the relationship between geometry elements in good measure,the user can effectively draw various geometric figures in a scientific document without any assistant of other tools. |
