This workflow is designed to generate artistic QR codes.

Here are some tips for using my workflow:

1. The following three features are optional:

- FaceDetailer

- Upscale

- IPAdapter: If you want to enable this feature, you need to increase the weight of ControlNet.

2. About Image Size:

- If the original QR code size is less than 768, the scannability of the resulting image may be poor. You need to set the Size of EmptyLatentImage to ≥768.

- If the original QR code size is greater than 768, you can directly pass the image size to EmptyLatentImage.

3. If your QR code has poor scannability, the most direct way to improve it is to increase the weight of the ControlNet model QrCodeMonster.
