this is a completely vanilla javascript and html canvas outpainting convenience built for [AUTOMATIC1111's stable diffusion webUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui) similar to a few others which certainly have superior functionality. this simply offers an alternative for my desires:
technically you can run it directly in browser as a bare `file://` protocol webpage but that's _really_ not recommended as you'll have to add `null` as an accepted domain to your `--cors-allow-origins` option which just seems like it's a visibly poor decision.
i therefore **strongly** recommend using a small webserver such as [simple-http-server](https://github.com/TheWaWaR/simple-http-server) if you don't have a local server already running somewhere.
1. clone this repo or just literally download index.html and js/index.js manually and put 'em somewhere
2. configure whatever local (host or network) webserver you're using to serve the index.html from this repo and execute it (instructions for configuring a web server are outside the scope of this remedial quickstart)
3. modify your `webui-user.sh` or `webui-user.bat`'s `COMMANDLINE_ARGS` variable to contain ` --api --cors-allow-origins=http://127.0.0.1:1234`*(replacing 127.0.0.1:1234 with wherever you're hosting it on your local network if necessary)*
4. execute your webui-user script and wait for it to be ready
5.**SELECT AN INPAINTING MODEL (and associated VAE if applicable) IN WEBUI** - [runwayml/stable-diffusion-inpainting](https://huggingface.co/runwayml/stable-diffusion-inpainting) is recommended
6. open your locally-hosted web server, possibly appending `index.html` if it doesn't automatically serve that
7. update the host field if necessary to point at your stable diffusion API address, change my stupid prompts with whatever you want, click somewhere in the canvas, and wait
8. once an image appears*, click the `<` and `>` buttons at the bottom-left corner of the image to cycle through the others in the batch if you requested multiple (it defaults to 2 batch size, 2 batch count) - click `y` to choose one you like, or `n` to cancel that image generation batch outright and possibly try again
9. now that you've got a starter, click somewhere near it to outpaint - try and include as much of the "context" as possible in the reticle for the best result convergence
10. use the mask mode to prepare previously rendered image areas for touchups/inpainting
11. play around with the available options, click "dl img" to save the entire 2560x1440 canvas, sorry it doesn't smart crop or anything
- [ ] controls for the rest of API-available options (e.g. hires fix, inpaint fill modes, etc)
- [ ] figure out where that stupid 1-pixel offset is happening between approve/reject state and committing to an image, it doesn't affect output but it's _super_ obnoxious
- [ ] BUG: make erase mask actually work, enable the control if you dare
i am begging you, yes you personally reading this, please fix my horrible code and feel free to insult it, but i absolutely refuse to budge on no 3rd party libraries or dependencies, not even jquery, nothing. vanilla is a very complex and layered flavor if you give it a chance.
generated using 100% openOutpaint UI defaults except for switching to/from mask mode and changing scale factor to adjust the size of the mask blob, there's some neat stuff down there even if it disregarded the `people, humans, divers` negative prompt but in its defense there is only one singular person, human, diver in there, so according to the no homers club treatise of 1995 it's technically correct
