paintDiffImages

paintDiffImages(result: DiffImagesResult, paint?: DiffImagePaint & { picture?: number }): DiffPixels

DiffPixels paintDiffImages(DiffImagesResult result, {DiffImagePaint? paint, int? picture});

The same step between an answer and a file that paintDiffImage is, for a comparison of a list. With no picture it paints every pixel any of them disagrees about, which is the one image a build attaches to a run that compared four. With one, it paints what that picture alone disagrees with the baseline about — four files, one a picture, saying who is the odd one out where.

added and removed do not apply here, so only changed and unchanged are read off the colours: whose arrival a pixel is depends on which of the pictures is being asked about, and the answer for a list is that they disagree.
