从数据结构、存储方式两方面对比CAD点状符号与TrueType符号的符号模型,提出两者间的转换方法,设计出符号的双向映射机制。利用该方法进行符号转换实验,针对转换前后符号出现的数据量变化、变形以及信息丢失等问题进行了详细分析,实验结果表明,该方法能够实现CAD点状符号与TrueType符号之间的转换,有助于符号之间的共享。 更多还原

【Abstract】 This paper aims at symbol sharing between CAD and TrueType.First,point symbol model between CAD and TrueType were compared from data structure and storage style.Second,conversion methods between them were proposed and some issues such as data size,information distortion and lost on fore-and-aft conversion were analyzed.Experiment validates the feasibility of conversion between CAD and TrueType point symbols and it help to symbol sharing. 更多还原
