[Panchovix]

See #291 for more details.

Adapted for main branch.

Description

Forge has Gradio 4. So I tried porting reForge to Gradio 4. The current status is that while WebUI launches without any errors on the python side, it gets stuck on a Dropdown.

Currently Fixing all the python side and interactivity. More or less done. Looking for bugs

Screenshots/videos:

Screenshots for postery and log of what works and doesn't work:

PNG Info

Slight issue where the width and height does not get sent properly. But prompts are properly sent.

Txt2Img Generation

Generated image with APG Extensions enabled and first proper waifu generated. :

Fixed imageviewer.js so the full screen image viewer also works too.

Img2Img Generation

Tested all 4. Seems to work

Deobfuscated forgeCanvas.js

Might be a hot take but anyway, deobfuscating the js so that people can work on it.

ForgeCanvas is "Touch compatible"

Your fingers on mobile are happier with a touch compatible forge canvas. While there are UI issues + (Zoom and Pans are not tested). You can comfortably doodle on the image.

Bugs & Missing Features

• Width & Height doesn't get sent properly from png info / image inspector? Someone verify that's correct behaviour.
• kohya_hrfix.py doesn't load. Fixed
• ControlNet doesn't work due to new ForgeCanvas Fixed
• ForgeCanvas does not work with mobile. Fixed
• 4.40.0 is the latest version that this can be ported. Past that, InputAccordion is broken.
• Sometimes this random stacktrace might appear. But doesn't affect functionality.

Extension Issues

• sd-webui-additional-networks doesn't launch due to the following error. Since the extension is like 2 years old... Not in current scope to fix it anyway.

  *** Error executing callback ui_tabs_callback for G:\Stable difussion\stable-diffusion-webui-reForge\extensions\sd-webui-additional-networks\scripts\additional_networks.py

    AttributeError: 'Row' object has no attribute 'style'
  

• stable-diffusion-webui-model-toolkit doesn't load with the following. Likely due to gradio 4 upgrade. But should be relatively easy to fix.
