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.

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:

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

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