摘要
介绍了二维条码PDF417的编码原理,给出了在文本压缩模式下编码的程序流程图,并且用Visual Basic语言完成了其编码打印软件。经实验验证所编程序可以准确无误地实现PDF417条码的编码和打印,与此同时本软件还具有可以实时观察编码各个阶段编码数据变化的特点,十分有利于分析编码数据。
The theory of coding two dimension barcode - PDF417 is introduced in this paper. The flow chart of coding barcode is given, and the software for coding and priming is developed with Visual Basic. The experiment shows that the program functions well. Furthermore, the data in different coding phases can be real - time observed through this software, which is of great help in coding data analysis.
