Write generation parameter exif data into output pngs. #57
Conversation
This adds prompt, negative prompt (if nonempty) and other generation parameters to the output file as a tEXt PNG block, in the same format as AUTOMATIC1111 webui does. In order to keep everything free of external library dependencies, I have somewhat dirtily hacked this into the stb_image_write implementation.

I think it should always be included in the image; it doesn't take up space anyway. Whether you want to read it or not will depend on each person, but as a preventive measure, that information should always be included. Edit: |
The best case would be to have support upstream (stb), but that is unlikely, to happen soon, even if you open a perfect pr there now 😞 . I am move of an advocate to keep dependencies clean and work around the limit in the client code, maybe wrap it. I proposed your dirty approach here too 😄
how about opt-out? |

Sure. Make that always-on or opt-out. Makes little sense to accommodate just the few people who don't want to share their workflow or keep it a secret they did their homework assignment with ChatGPT ;-) |

Great! |
