QR code

Weaves a scannable QR code carrying this text or URL into the image itself.

The code is part of the picture rather than pasted over it, so the prompt still decides what the image is of.Ask for weather, vapour, foliage and light rather than blocks and hard shadows. The ControlNet already carries the code, and a prompt that describes geometry competes with it for the same pixels.Beside the payload, the request can carry where the code sits, in pixels from the left and top edge, and which shape its squares are drawn as. Left alone, the workflow centres a square code.Control strength says how closely the image follows the code, and the QR workflow takes it. Leave it unset and the request carries nothing for it, so the worker uses its own 1. The slider in the QR card sets it.The examples on this page were made across that range on local software. Read them for what the range does to a code, and for how much of a scannable code comes from the prompt and its texture rather than from the number.A few more things hold for every QR request:
  • It needs a Stable Diffusion 1.5 or SDXL model.
  • These requests are never batched, so each image in a batch is queued on its own.
  • Leave the box blank and the workflow is not used at all.

Use this much when people really need to scan the code: readable across a room, still made of weather.
