参数SymbolType 中IdentifySymbolType 算法的搜索顺序。

搜索二维码

•"数据矩阵 ECC 200"/"GS1 DataMatrix"、"QR 码"/"GS1 QR 码

•"Micro QR 码"、"阿兹台克码"/"GS1 阿兹台克码"、"PDF417"。

•对于二维码，首先检查它是否是标准变体。如果是，则检查其是否为 GS1 变体。

搜索一维代码

•"GS1 DataBar Omnidir"、"GS1 DataBar Truncated"、"GS1 DataBar Stacked"。

•"GS1 DataBar Stacked Omnidir"、"GS1 DataBar Limited"、"GS1 DataBar Expanded"。

•"GS1 DataBar Expanded Stacked"，"GS1-128"，"Code 128"，"EAN-13 Add-On 5

•"EAN-13 Add-On 2"、"EAN-13"、"UPC-A Add-On 5"、"UPC-A Add-On 2"、"UPC-A"。

•"EAN-8 Add-On 5"、"EAN-8 Add-On 2"、"EAN-8"、"UPC-E Add-On 5"、"UPC-E Add-On 2"

•"UPC-E"、"Code 93"、"Code 39"、"Codabar"、"2/5 Interleaved"、"2/5 Industrial"

信息：

符号类型 8（MSI）和符号类型 9（PharmaCode）不包括在搜索序列中，因为在许多情况下，尽管不存在代码或错误代码，但由于缺少校验属性，这些符号类型会提供假阳性结果。

Searching for 2D codes

•"Data Matrix ECC 200" / "GS1 DataMatrix", "QR Code" / "GS1 QR Code"

•"Micro QR Code", "Aztec Code" / "GS1 Aztec Code", "PDF417"

•For 2D codes, first check as to whether it is a standard variant. If yes, then check as to whether it is a GS1 variant.

Searching for 1D codes

•"GS1 DataBar Omnidir", "GS1 DataBar Truncated", "GS1 DataBar Stacked"

•"GS1 DataBar Stacked Omnidir", "GS1 DataBar Limited", "GS1 DataBar Expanded"

•"GS1 DataBar Expanded Stacked", "GS1-128", "Code 128", "EAN-13 Add-On 5"

•"EAN-13 Add-On 2", "EAN-13", "UPC-A Add-On 5", "UPC-A Add-On 2", "UPC-A"

•"EAN-8 Add-On 5", "EAN-8 Add-On 2", "EAN-8", "UPC-E Add-On 5", "UPC-E Add-On 2"

•"UPC-E", "Code 93", "Code 39", "Codabar", "2/5 Interleaved", "2/5 Industrial"

Information:

Symbol types 8 (MSI) and 9 (PharmaCode) are not included in the search sequence since these would provide a false positive result in many cases due to their missing check properties, although no code or a faulty code exists.
