3-Inpaint

In this example we will be using this image. Download it and place it in your input folder.

This image has had part of it erased to alpha with gimp, the alpha channel is what we will be using as a mask for the inpainting. If using GIMP make sure you save the values of the transparent pixels for best results.

ComfyUI also has a mask editor that can be accessed by right clicking an image in the LoadImage node and “Open in MaskEditor”.

The following images can be loaded in ComfyUI to get the full workflow.
