ComfyUI Extension: ComfyUI-NegiTools

ComfyUI-NegiTools Introduction

ComfyUI-NegiTools is an extension designed to enhance the capabilities of ComfyUI, a user interface for AI-based image generation. This extension provides a variety of tools and features that can help AI artists create more sophisticated and customized images. Whether you are looking to generate images using OpenAI's DALL-E3, add noise to images, estimate depth, or translate text, ComfyUI-NegiTools has you covered. It simplifies complex tasks and offers a range of utilities to make your creative process smoother and more efficient.

How ComfyUI-NegiTools Works

ComfyUI-NegiTools integrates seamlessly with ComfyUI, adding new nodes and scripts that you can use in your workflows. Each tool within the extension performs a specific function, such as generating images, adding noise, or translating text. These tools are designed to be user-friendly, requiring minimal setup and configuration. For example, the DALL-E3 generator node uses the OpenAI API to create images based on your prompts, while the noise generator node allows you to add various types of noise to your images. By breaking down complex tasks into simple, manageable steps, ComfyUI-NegiTools makes it easier for you to achieve your artistic vision.

ComfyUI-NegiTools Features

Generator/OpenAI DALL-E3

This feature allows you to generate images using OpenAI's DALL-E3 model. You can specify a prompt in any language, and the model will create an image based on that prompt. The resolution of the output image can be selected from predefined options. A unique dummy_seed parameter helps manage caching, ensuring that repeated prompts yield consistent results unless the seed is changed.

Generator/Noise Image Generator

This tool generates noise images that can be used for various artistic effects. You can specify the type of noise (uniform, Gaussian, Perlin, etc.), the image dimensions, and other parameters like seed, scale, and bias. The noise can be added to specific areas of an image using a mask.

Generator/Depth Estimation by Marigold (Experimental)

This experimental feature uses the Marigold model to estimate depth in images. Note that this module is not actively maintained and may be discontinued in the future. For continued use, consider switching to the extension.

Generator/Stereo Image Generator

This tool generates stereo images, which can be used to create 3D effects. It leverages an image transformation algorithm from the extension.

utils/OpenAI Translate to English

This utility translates text from any language into English using GPT-4. It is particularly useful for creating prompts in languages other than English for input into Stable Diffusion.

utils/String Function

This feature allows you to generate strings using custom Python scripts. You can input optional strings and use them within your script to create dynamic text outputs.

utils/Seed Generator

This tool generates integer seed values for use in image generation. It can be set to random or keep_previous, allowing you to maintain consistency in your results or explore new variations.

utils/ImageProperties

Outputs the properties of an image, such as its resolution (width and height).

utils/LatentProperties

Outputs the properties of a latent image, including its resolution.

utils/CompositeImages

This tool allows you to composite two images using an alpha value. You can specify the background and foreground images, as well as an optional mask to control the compositing process.

utils/OpenPoseToPointList

Detects key points on the human body using OpenPose and outputs the results as a JSON string. This can be used in combination with the PointListToMask utility to generate masks based on key points.

utils/PointListToMask

Generates a mask from the coordinate list output by the OpenPoseToPointList utility.

Troubleshooting ComfyUI-NegiTools

Common Issues and Solutions

1. API Key Errors: Ensure that your OpenAI API key is correctly set in the environment variable OPENAI_API_KEY.
2. Image Generation Failures: Check that your prompts are correctly formatted and that you have selected a valid resolution.
3. Noise Generation Issues: Verify that the parameters for noise type, scale, and bias are set correctly.
