  We obtain a complete description of anisotropic scaling limits and the
existence of scaling transition for a class of negatively dependent linear
random fields on ${\mathbb{Z}}^2$ with moving-average coefficients $a(t,s)$
decaying as $|t|^{-q_1}$ and $|s|^{-q_2}$ in the horizontal and vertical
directions, $q_1^{-1} + q_2^{-1} < 1 $. The scaling limits are taken over
rectangles whose sides increase as $\lambda $ and $\lambda^\gamma $ when
$\lambda \to \infty$, for any $\gamma >0$. We prove that the scaling transition
%and the structure of the scaling diagram in this model is closely related to
the presence or absence of the edge effects.
