import sys, qrcode d = qrcode.Decoder()ifd.decode('out.png'):print'result: '+ d.resultelse:print'error: '+ d.error 所以我只是使用sudo pip install pyqrcode安装了它。然而,我对上面的示例代码感到奇怪的是,它只导入qrcode(而不是pyqrcode虽然)因为我认为qrcode–它只能生成二维码图像,这让我有...
使用Python的qrcode库可以在QR Code中嵌入PDF。下面是完善且全面的答案: QR Code(Quick Response Code)是一种二维码,可以存储大量的数据信息。Python的qrcode库是一个强大的库,可以用于生成QR Code。为了在QR Code中嵌入PDF文件,我们可以遵循以下步骤: 导入qrcode库和其他必要的库: 代码语言:txt 复制 import qrcod...

压缩算法称为编码器(coder),解压算法称为解码器(decoder),编解码算法统称为编解码器(codec)。视频文件能否读写,关键看是否有相应的编解码器。编解码器的种类非常多,常用的有MJPG、XVID、DIVX等。视频文件的扩展名(如avi等)往往只能表示这是一个视频文件,我们并不能由其得知实际的编解码器。 OpenCV提供了两个类...
