Java WeChatQRCode

Java uses version 4.7.0, why can’t I find the WeChatQRCode class

the wechat qr code is from the opencv_contrib repo,
you have to rebuild the sdk from src (with contrib modules) to use that.

however, you can still use the QRDetector class from opencv main

Do you have an integrated Java version of the jar and DLL

me ? no.

prebuilt windows release should contain java jar/lib/dll, but again, NOT the contrib modules
