摘要:: Micro QR是ISO/IEC 18004：2006标准中提出的一个新特性，结构附加模式是QR码的一种容量扩展特性。经过对现有二维码开源软件的调研，发现目前没有对这两种特性提供支持的。为提供对这两种编码功能的支持，对现有的ISO标准化文档和开源二维码软件代码进行了分析。发现开源软件Zxing的代码有逻辑清晰、方便扩展和良好编码风格等特性。因此，通过对比和研究Micro QR和结构附加模式编码步骤与Zxing的QR码编码实现方法，对Zxing代码进行了修改和扩展，完成了这两种特性的代码实现。使其完全支持Micro QR和结构附加模式的编码，并通过实例程序验证了生成的二维码图像的正确性

Abstract:: Micro QR is new feature in ISO/IEC 18004:2006 specification. Structured appending mode is a feature of capability expansion to QR. By investigating barcode there are few open source project to support them. To support them investigate lots of ISO's specification and popular barcode project. In conclusion Zxing is an excellent project which is more easy to develop,more useful than others and good code style. Therefore,compare and research the coding steps of Micro QR and structured appending mode and the realization method of QR coding of Zxing,which is modified and expanded,achieving the coding realization of two features. Make open source project Zxing to support Micro QR and structured appending mode,and the correctness of the barcode images is verified by a instance
