Padding Bytes就是重复下面的两个bytes:11101100 00010001 (这两个二进制转成十进制是236和17,我也不知道为什么,只知道Spec上是这么写的)关于每一个Version的每一种纠错级别的最大Bits限制,可以参看QR Code Spec的第28页到32页的Table-7一表。

The QR Code specification says to use the (18, 6) Golay code for the version information string. As such, the version information string is an 18 bit string that consists of a six bit binary string that encodes the QR version, followed by a string of 12 error correction bits. The entir...
没有达到我们最大的bits数的限制,我们还要加一些补齐码(Padding Bytes),Padding Bytes就是重复下面的两个bytes:11101100 00010001 (这两个二进制转成十进制是236和17,我也不知道为什么,只知道Spec上是这么写的)关于每一个Version的每一种纠错级别的最大Bits限制,可以参看QR Code Spec的第28页到32页的Table-7一...
So how can QR Codes help you improve table tents? 1. Small space, more information A QR Code provides instant access to a large amount of information hidden within its matrix. Table tents are a great opportunity to promote new drinks or menu items at restaurants for instance, or new ...

如下所示:(其中的 SP 是空格,Char 是字符,Value 是其索引值) 编码的过程是把字符两两分组,然后转成下表的 45 进制,然后转成 11bits 的二进制,如果最后有一个落单的,那就转成 6bits 的二进制。而编码模式和字符的个数需要根据不同的 Version 尺寸编成9, 11 或 13 个二进制(如下表中 Table 3)...
