Import myqr Library

In PyCharm, open File → Settings → Project → Python Interpreter , click the + button, search for MyQr, select the first result and click Install Package. After installation, you can start using the library.

1. Generate a Simple QR Code

First import the library (note the case sensitivity): from MyQr import myqr # 注意大小写 Then generate a QR code with a URL or text: myqr.run(words='https://baidu.com') The QR code image ( qrcode.png) will be saved in the directory where the script is executed.

2. Generate a QR Code with a Custom Image

Add the picture argument to embed an image into the QR code:

from MyQR import myqr
myqr.run(
    words='https://baidu.com',
    picture='C:\Users\jinyj\Desktop\p1.png'  # or use raw string r'C:\...'
)

3. Generate a Colorized QR Code

Set colorized=True to produce a colored QR code:

from MyQR import myqr
myqr.run(
    words='https://baidu.com',
    picture='C:\Users\jinyj\Desktop\p1.png',
    colorized=True
)

4. Advanced Parameters (Optional)

The myqr.run() function supports many additional arguments for fine‑tuning:

from MyQR import myqr
myqr.run(
    words='URL or text (no Chinese characters)',
    version=5,               # error correction capacity
    level='H',               # error correction level (L, M, Q, H)
    picture='image.png',    # can be a static image or GIF
    colorized=True,
    contrast=1.0,
    brightness=1.0,
    save_name='custom_qr.png',
    save_dir=r'C:\Users'
)

These parameters allow you to control the QR code size, error correction level, embedded picture, color mode, contrast, brightness, output filename, and storage location.

5. Animated QR Code

You can also use an animated GIF as the picture argument; the process is identical to the static image case.
