importqrcode 3.1生成简单的文本二维码 生成一个简单的文本二维码非常简单。以下是一个示例代码：pythonCopy code# 创建QRCode对象qr = qrcode.QRCode(version=1, error_correction=qrcode.constants.ERROR_CORRECT_L, box_size=10, border=4)# 设置二维码的数据data = "Hello, World!"qr.add_data(data)# ...
为了存储 bit 并方便使用,我使用了 bit_thing 库。此外,为了方便处理信息,我创建了一个 QrCodeBitvec 结构,它包含三个字段:一个用于存储服务信息(编码类型和字符数)的字段、一个用于存储数据的字段和一个用于存储纠错字节的字段。 举个例子,为了说明这个系统是如何工作的,我将数字 1234 编码成一个二维码。 首先...

The size of the QR code dots depends on the amount of information you store in the code. The more information that needs to be stored, the smaller the size of the dots will be. It happens when you use static QR codes. If the QR code has smaller dots, your phone will have trouble ...
Capacity depends on symbol version and error correction level. Also encoding modes may influence the amount of storable data. The QR Code versions range from version1to version40. Each version has a different number of modules (black and white dots), which define the symbol's size. For versio...
This extension allows multiple QR codes to be tracked and can provide size, position, last detection timestamp, UUID, and buffered QR code data for detected QR codes.To enable QR code support, both the XR_MSFT_scene_marker and XR_MSFT_scene_understanding extensions must be enabled....
