Introduction

Expanding images has always been a challenging task, often involving a time-consuming process with hit-or-miss results. But with the advent of Stable Diffusion img2img, coupled with the powerful ControlNet Inpaint + LAMA, this once daunting task has become a streamlined process. Gone are the days of frustration and subpar expansions. In this post, I'll dive straight into how this innovative approach can revolutionize your image editing workflow, making outpainting a breeze.

What is Outpainting?

First things first, let's talk about what outpainting is. Outpainting, or image expansion, is the process of extending the boundaries of an image to create a larger canvas while maintaining the original content's style and context. This technique is particularly useful for artists, designers, and content creators who want to enlarge their images without losing quality or coherence.

Traditionally, outpainting an image could take up a significant amount of time and effort, often requiring multiple attempts to achieve a satisfactory result. However, with the introduction of ControlNet Inpaint + LAMA, you can now achieve this in just one generation, saving you both time and frustration.

2. Next, enable the Control feature. This is where the magic happens.
   • Select Inpaint as your control type. This option allows you to specifically target areas of the image you want to expand.
   • Click on Upload independent control image and upload the same image you're working with. This step is crucial as it gives you access to the resize and fill option.
