摘要
为了解决二维码在证件类应用中常常面临的冷僻字编码问题,以GB18030字符集为对象分析汉字编码特点,提出基于该标准的汉字与ASCII混合信息的PDF417编码方法。并针对当前广泛应用的16位编程工具,结合实例给出了一种拆分迭代编码算法来实现字节压缩模式,它能够在保证较高编码效率的基础上有效节省编码存储空间。
It is very important for the wide use of 2D bar codes in certificates to encode the Chinese ideograms that are rarely seen and used in social life while more people would like to have them in the name to show its uniqueness. GB18030---2005 character set makes it possible to solve such a question with nearly 27000 Characters included. The encoding regulations for Chinese ideograms in GB18030 were analyzed here and then the 2D bar code PDF417 encoding method of the mixed information of Chinese ideograms with ASCII characters was put forward. A special byte-compresslon method named spilt-iterated algorithm which could save memory without loss of encoding efficiency and could be realized on 16-bit programming tools was introduced here too. An example was given in this paper to illustrate the whole encoding process.
