ComfyUI Extension: Olm DragCrop for ComfyUI

ComfyUI-Olm-DragCrop Introduction

ComfyUI-Olm-DragCrop is an innovative extension designed to enhance your image editing workflow within ComfyUI. This extension provides an interactive image cropping node that allows you to visually select and adjust crop areas directly within your workflow. It is particularly useful for AI artists who need precise control over image dimensions without the hassle of using external image editors. With ComfyUI-Olm-DragCrop, you can streamline the process of preparing images for various tasks, such as inpainting or outpainting, by offering immediate visual feedback and control over your image dimensions.

How ComfyUI-Olm-DragCrop Works

At its core, ComfyUI-Olm-DragCrop operates by allowing you to define a crop area through a simple drag-and-drop interface. Imagine having a transparent overlay on your image where you can draw a rectangle to specify the area you want to keep. This rectangle can be moved and resized with ease, providing a real-time preview of the cropped area. The extension eliminates the need for manual calculations of pixel offsets, making it accessible even to those who are not technically inclined. By integrating directly into ComfyUI, it ensures that you can make adjustments without leaving your current workflow, thus saving time and effort.
