We report a way of obtaining a spin configuration snapshot, which is one of the representative spin configurations in the canonical ensemble, inside a finite area of infinite size two-dimensional (2D) classical lattice models.The corner transfer matrix renormalization group (CTMRG), a variant of the density matrix renormalization group (DMRG), is used for the numerical calculation.The matrix product structure of the variational state in CTMRG makes it possible to stochastically fix spins each by each according to the conditional probability with respect to their environment.
