Hi all !

I am using Libvips which is proving to be fantastic for fast image processing in an image editor I am working on, and a feature that I have been looking for is some sort of image inpainting to fill zones based on local content according to a mask. For now, I use OpenCV but it is a little cumbersome to exchange back and forth with Vips, and OpenCV's inpainting options are pretty painfully slow as there is no optimization for parallel processing of inpainted areas. In my use-case, "classic" algorithms like fluid-dynamics-based ones are more than adequate as the defects to correct are small and thin, so it does not warrant heavier solutions like patch-match. With that said, I guess that a simple median filter might also work, which should be feasible with existing Vips tools, but I feel like this could still be a fantastic feature to support natively !

Thanks for the fantastic work and have a nice day,
Adrien
