Outpainting mk2 - Expand more than 256 px - API 128 px limit bug

[Expertaz]

Hello, I was playing with the "Outpainting mk2" script a bit and I realize how amazing it is. But I have some problem when I push it to its limits. First of all the pixel limit extended to 256 is small so I increased it in the code but I have a problem that the image that is generated does not take into account the original image. It work well up to about 350.

Even crazier, even below 200 pixels to extend the image is off when called from the API (it works well up to about 128 pixels)

Has anyone found a solution to stretch an image over 256 pixels?

Thank you in advance !

I was just trying to extend this limit myself. I opened the script in Notepad+ and changed the max from 256 to 512, but when I restart Automatic1111, the changes don't show up on the UI. The slider still maxes out at 256. How did you get your changes to take effect?

Very late, but I actually found solution.
To make size larger, you should look into file webui/ui-config.json and change value in

"customscript/outpainting_mk_2.py/img2img/Pixels to expand/maximum"

to desired. Also, good thing to do probably is to remove webui\scripts_pycache_ to regenerate pyc fles.

Note, that setting high value may probably cause NaN tensor to appear (can be avoided by changing settings). Also, this outpainting method gives inconsistent outpainting results on large values, so it's not really good thing to do.
