This plugin provides two nodes to provide a full page editor that runs in another tab.

There is an input node Edit in another Tab and an output node Send to Editor Tab.

Both are stored in the images submenu.

The can be set to trigger a queue on change. if there is something in the queue already it will wait until the queue empties before

triggering a new Queue. This should result in only one queued entry triggered by this node at a time.

Installation

You can install either though comfy manager or by cloning this repository into the custom nodes directory.

User Interface

You can edit multiple images at once.

Drag images around with the middle mouse button and scale them with the mouse wheel.

There is a green Tab on the side of images in the editor, click on that tab to highlight it.

The image with the highlighted tab is sent through to the comfyUI node.

Multiple Canvas Tab nodes are supported, If the title of the node and the title of the image in the editor are set to the same name

The output of the canvas editor will be sent to that node.

You can have multiple image layers and you can select generated images to be

added as a new layer, replace an existing layers, or as a new image.

You can delete layers by clicking on the layer widget with Ctrl-LeftClick. The layer must be visible for this to work as a protection against unwittingly deleting something important.

Ctrl-click on palette entries reassigns the palette color tho the current color.

Middle-click on palette entries sets the palette color to the current foreground color.

Both nodes provided by this extension support receiving files by drag and drop to

send images directly to the editor.

Why would you do such a thing?

My main motivation for making this was to develop an inpainting workflow,

but I have also found it quite useful for scribble based images,

This image shows a basic workflow where it simply sends the image back to itself and shows

previews of the image and mask. The workflow is also embedded in this image.

I have been using the controlnet inpaint with a workflow like this.

That workflow should be embedded in this image.
