ComfyUI Tutorial+Workflow: Inpainting only on masked area, fast outpainting, and seamless blending

This tutorial presents novel nodes and a workflow that allow fast seamless inpainting, outpainting, and inpainting only on a masked area in ComfyUI, similar to the AUTOMATIC1111 feature but with extra flexibility. The main advantages of inpainting only in a masked area with these nodes are: - It's much faster than sampling the whole image. - It enables setting the right amount of context from the image for the prompt to be more accurately represented in the generated picture. - It enables upscaling before sampling in order to generate more detail, then stitching back in the original picture. - It enables downscaling before sampling if the area is too large, in order to avoid artifacts such as double heads or double bodies. - It enables forcing a specific resolution (e.g. 1024x1024 for SDXL models).. - It doesn't modify the unmasked part of the image, not even passing it through VAE encode and decode. - The nodes take care of good blending. The Inpaint Crop and Stitch nodes can be downloaded using ComfyUI-Manager, just look for "Inpaint-CropAndStitch". The example workflow featured in this video can be downloaded from https://github.com/lquesada/ComfyUI-Inpaint-CropAndStitch I hope you like them!!
