摘要
PDF417是一种应用最为广泛的二维条码,实现其生成优化可使其应用更加方便、高效。二维条码PDF417有多种数据压缩模式,针对各种数据压缩模式,提出了一个简便的适用于多级纠错等级的解决方法;应用VB编程处理复杂多项式计算,实现了数据压缩编码算法的优化,从而使在整体数据压缩后,码字数目得到减少。该方法可用于PDF417数据压缩生成实现,促进了二维条码的应用和普及。
The purpose of this research was to develop software to optimize PDF417 bar code data compression using VB. According to the different compression, some relevant approach which optimizes the coding ar/thmetic of data compression was put forward. A simple approaeh to compute complex polynomial was introduced. So after the whole data compression, the number of the codeword will be reduced. The method and software was practical to generate PDF417 bar code.
