      This tool allows you to apply a Stable Diffusion text prompt to an existing image composition using an edge-tracing tool called Canny Edge Detector. Note that you cannot currently apply trained artist concepts from the other tabs in this application to this process currently as they were trained using a more recent version of Stable Diffusion.
