Introduction

Img2Img is a powerful feature in LightDiffusion-Next that allows you to generate new images based on existing ones. By providing a source image and a text prompt, you can create stunning transformations and enhancements.

Prerequisites

Before you begin, ensure you have the following:

  • LightDiffusion-Next properly installed on your system.
  • A source image that you want to transform.
  • Basic understanding of how to create prompts in LightDiffusion. Refer to the Prompting Guide for more information.

Basic Usage

Using the GUI

  1. Launch LightDiffusion-Next: Start the application using run.bat (Windows) or run.sh (Linux).
  2. Set Parameters:
    • Enter your prompt describing the desired output
    • Set the denoising strength (how much change will be applied)
    • Configure other settings like width, height, and sampling method
  3. Generate: Click the “Img2Img” button to select and transform your image.

Using the CLI

To use Img2Img in the command-line interface:

./pipeline.bat "path/to/your/image.png" width height number_of_images batch_size --img2img

For example:

./pipeline.bat "./_internal/output/Classic/LD_00001_.png" 1024 768 1 1 --img2img

Tips and Tricks

  • Experiment with CFG Scale: The CFG scale controls the adherence to the prompt. Higher values result in more adherence but can lead to overfitting.
  • Use High-Quality Descriptions: Detailed and specific descriptions yield better results.
  • Leverage Negative Prompts: Use negative prompts to filter out unwanted elements.
  • Iterate and Refine: Generate multiple images and refine your prompts based on the results.

Troubleshooting

If you encounter issues with Img2Img, consider the following:

  • Check for Typos: Ensure there are no typos in your prompt.
  • Simplify Your Prompt: Start with a simple prompt and gradually add complexity.
  • Open an Issue: If you encounter persistent issues, open an issue on the LightDiffusion-Next GitHub repository

Wish you good generations!
