标准范围

ISO/IEC 24728:2006规定了称为MicroPDF417的条形码符号系统的要求。它指定了MicroPDF417符号特性、数据字符编码、符号格式、尺寸、纠错规则、解码算法和许多应用参数。MicroPDF417是一个多行符号系统，源自并紧密基于PDF417。MicroPDF417专为需要提高面积效率但不需要PDF417最大数据容量的应用而设计。一组有限的符号大小是可用的，以及用于每个符号大小的固定级别的纠错。模块尺寸由用户指定，以允许通过各种技术产生和读取符号。由于MicroPDF417的数据字符编码、其纠错方法以及其许多其他符号特性与PDF417的相同，因此这些特性的描述逐字引用自PDF417符号生物学规范（ISO/IEC 15438）在适当的情况下，或经过适当的修改。为了便于交叉引用，ISO/IEC 24728:2006遵循与PDF417符号规范相似的文档结构，在条款/子条款编号方面略有不同。

ISO/IEC 24728:2006 specifies the requirements for the bar code symbology known as MicroPDF417. It specifies the MicroPDF417 symbology characteristics, data character encodation, symbol formats, dimensions, error correction rules, decoding algorithm, and a number of application parameters.

MicroPDF417 is a multi-row symbology, derived from and closely based on PDF417. MicroPDF417 is designed for applications with a need for improved area efficiency but without the requirement for PDF417's maximum data capacity. A limited set of symbol sizes is available, together with a fixed level of error correction for each symbol size. Module dimensions are user-specified to enable symbol production and reading by a wide variety of techniques.

Since MicroPDF417's data character encodation, its error correction method, and many of its other symbol characteristics are, and are intended to remain, identical to those of PDF417, descriptions of these characteristics are quoted verbatim from the PDF417 symbology specification (ISO/IEC 15438) wherever appropriate, or with the appropriate modifications. For ease of cross-reference, ISO/IEC 24728:2006 follows a similar document structure, with minor differences in clause/subclause numbering, to the PDF417 symbology specification.
