The myqr library of python has the function of generating QR code, you can realize the characteristic QR code with just a few lines of code, come and try!
- First need to install myqr library
win+R open the command line
pip install myqr
2. After installation, you can happily program
The step is to import the library first, and then use the run function. Note that there are several important parameters in the function.
| parameter | effect |
|---|---|
| words | QR code content or link |
| picture | Custom QR code background image, support .jpg, .png, .bmp, .gif format, the default is black and white |
| colorized | QR code background color, the default is False, that is black and white |
| version | The size of the QR code, the range is [1,40] |
| level | Two-dimensional code error correction level, the range is {L,M,Q,H}, H is the highest level, default. |
| contrast | Contrast, the higher the value, the higher the contrast, the default is 1.0 |
| brightness | Brightness, the higher the value, the higher the brightness, the default is 1.0, the value is often the same as the contrast |
| save_name | QR code name, the default is qrcode.png |
| save_dir | QR code path, default is the program working path |
The main things you need to change here are the words parameter, the picture parameter, and the colorized parameter are generally set to True. Finally, the save_name and save_dir parameters are required to determine the QR code name and path.
Generally, the contrast parameter, version parameter, level parameter, and brightness parameter can be kept as default, and you don't care about it.
- The simplest QR code
from MyQR import myqr
myqr.run(words='https://blog.csdn.net/weixin_46530492',
save_name='try.jpg')
- QR code with custom background
Increase the parameters appropriately
from MyQR import myqr
myqr.run(words='https://blog.csdn.net/weixin_46530492',
picture='C:/Users/lenovo/Pictures/109951164593784012.jpg',
save_name='panxi.png',
save_dir='pictures',
colorized=True)
- Custom dynamic QR code
from MyQR import myqr
myqr.run(words='https://blog.csdn.net/weixin_46530492',
picture='C:/Users/lenovo/Pictures/20200518095751683.gif',
save_name='xinyuanjieyi.gif',
save_dir='pictures',
colorized=True)
The codes are almost the same, the difference is that the imported local pictures need to be in GIF format, and the save_name parameter also needs to be in .gif format.
The code has almost no skills, a lot of time is actually spent on finding pictures, go and try!
