Problem Description
Recently doing projects, need to generate two-dimensional code, use the qrious, found qrious generated two-dimensional code in the micro side slightly large white letters, but there is a fatal problem is with the micro sweep the letter can not be scanned successfully, the reasons for two-dimensional code-intensive, blurred, can not scan two-dimensional
identify the problem
Because only relatively large in the white micro-channel edge, started to think that environmental causes behind after removing some of the parameters on the link and found the white side is smaller, not so intensive. So that, this has nothing to do with the environment, but about the link itself with the parameters, the parameters with more, two-dimensional code becomes dense, leading scanning can not, as the white side, may be related to the intensity of the two-dimensional code ... ...
problem solved
Starting from the link itself, reduce the link parameters carried
