RefineFeature Class

sealed class RefineFeature

What ScanPicture.refine should do to a page: how to crop it, how to treat its colour, and which way up to leave it.

Pass a list holding at most one feature of each kind — one Rectify, one Profile, one Display, and so on. Kinds you leave out are left unchanged.

picture.refine(listOf(
    RefineFeature.Rectify.WithCutout(cutout),
    RefineFeature.Profile(RefineFeature.Profile.Type.Bitonal),
))
