Contraform in a text is everything that is not expressed directly, but still exists in the space of the work…
Say, the author concentrating on the character’s feelings skips the landscape description, in which the character stays. While skipping it he still holds it in mind and narrates as though the landscape is there. This non-depicted (or rather implied) landscape becomes a contra form to the text.
