Can we upload mask for ControlNet inpaint?

[w-e-w]

is possible
a while back out of curiosity I want see if I can implement some hack to do it using javascript
in the end I got something usable it's usable
basically I added two additional buttons that allows you to download or upload the mask
addition to this I also tried to add other functionalities such as eraser toole

video demo

output.mp4

if you want to try it, I uploaded the code on to a fork of my
https://github.com/w-e-w/stable-diffusion-webui/tree/canvas-experiment-w-e-w

the implementation is not with that issues specifically with compatibility with other things such as eraser or undo history
but if you're just using it to upload or download the mask it is totally usable

note that the implementation is done on base webui not controlnet
