Introduction

In the realm of digital art and image manipulation, inpainting has emerged as a powerful tool for restoring and enhancing images. LanPaint, a cutting-edge approach to inpainting, has garnered significant attention for its innovative custom K-Sampler implementation. This feature request aims to explore the possibility of porting LanPaint to the Diffusers framework, enabling universal inpainting capabilities.

Understanding LanPaint

LanPaint is an inpainting approach that leverages a custom K-Sampler to provide native support for every model. This unique feature allows LanPaint to seamlessly integrate with various models, making it an attractive option for artists and developers alike. The reference implementation for LanPaint is built on ComfyUI, which overrides various core functions to achieve its inpainting capabilities.

Porting LanPaint to Diffusers

The Diffusers framework, known for its modularity and flexibility, presents an ideal platform for porting LanPaint. By creating a custom scheduler, developers can import LanPaint into inpainting pipelines, as proposed in the issue comment on GitHub. This approach has already been successfully implemented for some modern Euler variants, demonstrating the feasibility of this feature request.
