🦜 Photopea Stable Diffusion WebUI Extension

Photopea is essentially Photoshop in a browser. This is a simple extension to add a Photopea tab to AUTOMATIC1111 Stable Diffusion WebUI.

In the tab, you will have an embedded Photopea editor and a few buttons to send the image to different WebUI sections, and also buttons to send generated content to the embeded Photopea.

Consider supporting Photopea by going premium!

Also consider using the much better integrated (and more actively maintained) Stable Diffusion PS Pea extension by huchenlei!

Installation

On your Stable Diffusion WebUI, click the Extensions tab, then the Install from URL internal tab in that section. Paste the URL for this repo and click Install.

Usage

In the Photopea extension tab, you will have the embedded Photopea window. It literally just embeds the exact same Photopea you'd have when accessing the website directly. You can learn how to use Photopea in their official documentation.

Options:

• Active Layer Only: if this box is ticked, only the currently selected layer in Photopea will be sent to the WebUI when using one of the buttons.
• iFrame height: by default, the Photopea embed is 768px tall, and 100% wide. If you have more or less monitor real estate, you can use the slider to increase or decrease the size of the Photopea window in your tab.

Buttons:

• Send to Extras: sends the currently opened image's flattened contents to the Extras tab. Useful for upscaling etc.
• Send to img2img: same as above, but sends the image to the img2img tab.
• Inpaint Selection: in case there's an area selected in the active document, will create a mask with that shape and send both the mask and the image to img2img's "Inpaint Upload" tab.

ControlNet:

In case you have the ControlNet extension installed, you'll also have:

• ControlNet model index dropdown menu: in the WebUI Settings tab, you can set up more than one ControlNet to be run at the same time. This dropdown lets you choose which model the image will be sent to.
• Send to txt2img ControlNet button: sends the image to ControlNet in the txt2img tab.
• Send to img2img ControlNet button: sends the image to ControlNet in the ixt2img tab.

WebUI image galleries

In the txt2txt, img2img and extras tab galleries (where your generated images appear), there will also be a Send to Photopea button. You can press it to send the currently selected image back to the Photopea tab. It will be added as a new rasterized layer to the currently open document.

You can also copy and paste the generated results normally into Photopea, and have multiple documents open etc.

Known bugs:

• When large files are passed in, they might not instantly be rasterized (this happens due to Photopea loading the image asynchronously, but sending the response to the load request before the image is fully loaded).
• In some scenarios, the `Send to Photopea`` buttons do not work. This appears to happen when they are created before the galleries are fully initialized. If you encounter this, try restarting the UI. If you have clear repro steps, please create an issue or comment to an existing one.
