this is a completely vanilla javascript and html canvas outpainting convenience doodad built for the API optionally exposed by [AUTOMATIC1111's stable diffusion webUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui), operating similarly to a few others which certainly have superior functionality. this simply offers an alternative for my following vain desires:
- a big ol' 2560x1440 canvas for you to paint all over _(infinite canvas area planned, in //todo already)_
- inpainting/touchup blob
- easily change samplers/steps/CFG/etc options for each "dream" summoned from the latent void
- optional grid snapping for precision
- optional overmasking for better seams between outpaints (suggested by @lifeh2o ([a](https://www.reddit.com/r/StableDiffusion/comments/ywf8np/i_made_a_completely_local_offline_opensource/iwl6s06/),[b](https://www.reddit.com/r/StableDiffusion/comments/ys9lhq/kollai_an_infinite_multiuser_canvas_running_on/ivzygwk/?context=3)) and i think it's a slick idea)
- "temporary" monitors at the bottom to see exactly what mask/image you're feeding img2img, no i'm certainly not using them as actual imagedata sources or anything
you'll obviously need A1111's webUI installed before you can use this, thus you're presumed to have an operational python install up and running to boot.
- 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
- a deliciously simple launch script (thanks [@jasonmhead](https://github.com/jasonmhead)! (https://github.com/zero01101/openOutpaint/pull/1)) is included to pop up a teensy tiny python-based local webserver, however you may have to manually `chmod +x openOutpaint.sh` on mac/linux
- the address http://127.0.0.1:3456 will be used as the host address for openOutpaint in the below quickstart; your local setup may use a different IP address or port. you can of course modify the included launch script to point at a different port than 3456 if desired, as well
1. clone this repo to your homelab's webserver (i mean who doesn't have a couple of those lying around?) or somewhere on your local pc
2. configure your local webhost in your homelab to serve the newly cloned repo like the technological bastion you are, or simply run the included `openOutpaint.bat` on windows or `openOutpaint.sh` on mac/linux.
3. modify your `webui-user.sh` or `webui-user.bat`'s `COMMANDLINE_ARGS` variable to contain ` --api --cors-allow-origins=http://127.0.0.1:3456`
5.**APPLY THE FOLLOWING SETTINGS IN A1111 WEBUI ONCE IT IS READY:**
- select an inpainting checkpoint/model - ([runwayml/stable-diffusion-inpainting](https://huggingface.co/runwayml/stable-diffusion-inpainting) [3e16efc8] is recommended)
- set your `Inpainting conditioning mask strength` to `1`
- disable the `Apply color correction to img2img results to match original colors.` option (the last 2 options are found under the stable diffusion category in the settings tab by default unless you've already moved it to your quicksettings list, and if so, you know where to set them already)
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. enable the mask mode to prepare previously rendered imagery for touchups/inpainting, then paint over the objectionable region; once your masked region is drawn, disable mask mode and change your prompt if necessary, then click over the canvas containing the mask you just painted to request the refined image(s)
- scale factor affects the size of both the painting reticle and mask blob
- ...everything else is pretty much just a regular stable diffusion option so i presume you know how you use those
12. click "dl img" to save the cropped region of outpainted canvas (thanks [@Kalekki](https://github.com/Kalekki)! (https://github.com/zero01101/openOutpaint/pull/2))
13. refresh the page to start a blank canvas and start all over only to discover that it's like 2 AM and you have to go to sleep because you have work in about 4 hours
- [ ] image erase region in case you decide later that you're not too happy with earlier results (technically i guess you could just mask over the entire region you dislike but that's... bad)
- [ ] import external image and scale/superimpose at will on canvas for in/outpainting
- [ ] "numpad" selector for determining how reticle is anchored against actual mouse cursor (currently works like a "5" [center] on the "numpad" paradigm)
- [ ] BUG: 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
- [ ] something actually similar to a "user interface", preferably visually pleasant and would make my mom say "well that makes sense" if she looked at it
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.
please do! kindly indicate your OS, browser, versions of both, any errors in devtools/console output, what you were trying to do, what you expected, what happened unexpectedly or incorrectly, if something caught fire (please call the fire department first), the usual
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

- 0.0.4.2 - pull requests (<3), downloaded images now have a timestamped name, css breakout because hopefully this will become halfway attractive enough to benefit from non-inline stylesheets [70ad4fe](https://github.com/zero01101/openOutpaint/commit/70ad4fe081bdbd507afc5af3cc2a4435924b66e3)
