This is an rMQR Code image generator implemented in Python. This is implemented based on ISO/IEC 23941:2022.

Please verify an image generated by this software whether it can decode correctly before use.

pip install rmqrcode

from rmqrcode import rMQR
import rmqrcode

data = "https://oudon.xyz"
qr = rMQR.fit(
    data,
    ecc=rmqrcode.ErrorCorrectionLevel.M,
    fit_strategy=rmqrcode.FitStrategy.MINIMIZE_WIDTH
)

The ecc parameter is an enum value of rmqrcode.ErrorCorrectionLevel to select error correction level. The following values are available:

• ErrorCorrectionLevel.M: Approx. 15% Recovery Capacity.
• ErrorCorrectionLevel.H: Approx. 30% Recovery Capacity.

The fit_strategy parameter is enum value of rmqrcode.FitStrategy to specify how to determine size of rMQR Code. The following values are available:

• FitStrategy.MINIMIZE_WIDTH: Try to minimize width.
• FitStrategy.MINIMIZE_HEIGHT: Try to minimize height.
• FitStrategy.BALANCED: Try to keep balance of width and height.

Here is an example of images genereated by each fit strategies for data Test test test:

from rmqrcode import QRImage

image = QRImage(qr, module_size=8)
image.show()
image.save("my_qr.png")

To select rMQR Code size manually, use rMQR() constructor.

qr = rMQR('R11x139', ErrorCorrectionLevel.H)
qr.make("https://oudon.xyz")

R11x139 means 11 rows and 139 columns. The following table shows available combinations.

The rMQR Code has the four encoding modes Numeric, Alphanumeric, Byte and Kanji to convert data efficiently. However, this package supoprts only Byte mode currently.
