ComfyUI Extension: Comfyui-Ycanvas

Comfyui-Ycanvas Introduction

Comfyui-Ycanvas is an innovative extension designed to enhance your digital art creation process by providing a dynamic and interactive canvas environment. This tool is particularly beneficial for AI artists who want to manipulate images with ease and precision. With Comfyui-Ycanvas, you can perform a variety of operations such as selecting, zooming, rotating, and transforming images directly on the canvas. The extension aims to streamline your workflow, allowing you to focus more on creativity and less on technical hurdles. Whether you're adjusting image sizes or experimenting with different layouts, Comfyui-Ycanvas offers a user-friendly interface to help you achieve your artistic vision.

How Comfyui-Ycanvas Works

At its core, Comfyui-Ycanvas functions as an interactive canvas node within your digital art software. Imagine it as a digital workspace where you can freely manipulate images. You can select an image by simply clicking on it, and deselect it by double-clicking or clicking on an empty area. Zooming in and out is as intuitive as scrolling your mouse wheel, while holding the Shift key allows you to rotate images. For more advanced transformations, pressing the ALT key lets you stretch or compress images by dragging them with your mouse. These operations are designed to be intuitive, mimicking the natural gestures you might use in a physical art studio.

Comfyui-Ycanvas Features

Comfyui-Ycanvas is packed with features that cater to the needs of AI artists:

1. Image Selection and Deselection: Easily select images with a click and deselect with a double-click or by clicking elsewhere on the canvas.
2. Zooming and Rotating: Use the mouse wheel to zoom in and out, and hold Shift while scrolling to rotate images. This allows for precise adjustments to your artwork.
3. Image Transformation: By holding the ALT key, you can stretch or compress images, giving you control over the proportions and dimensions of your artwork.
4. Matting Functionality: A dedicated button allows you to cut out parts of an image, enabling you to isolate elements and integrate them seamlessly into your composition.
5. Blending Modes: The latest update introduces blending mode options for images on the canvas. You can access these by selecting an image and using Shift+click to open the menu. This feature allows for creative layering and merging of images.
6. Canvas Size Adjustment: You can revise the canvas size and refresh the node interface by dragging, ensuring your workspace is always optimized for your current project.
