What are inpainting and outpainting features and how can they improve AI comic art?

Inpainting allows you to selectively edit parts of an existing image by providing a mask and a prompt. This is useful for fixing imperfections, adding details, or altering specific elements within a comic panel. Outpainting expands the borders of an image by generating new content that seamlessly blends with the existing image. This can be used to extend panels, create backgrounds, or add context. Both significantly enhance control and allow for refinements beyond initial generation.
