Processors for image masks

[Saquib764]

During my work flow, I frequently dilate/erode the masks to get the desired result. Currently, this has to be done outside ComfyUI, in python. It would be convenient to support this natively to speed up experimentation.

I have the same requirement as you, Have you solved it through automation?

[Saquib764]

Yes, I built a custom block using Kornia library, which works with pytorch tensor data type.

But it would be nice to have this as native feature.
