If I understand your problem correctly, the seg fault is occurring when x = -1 and y = 0. This is because you are trying to assign a value to a negative index in the matrix which is not allowed. Since you are trying to modify a place in memory you dont have access to, it seg faults.

saida->imagem[x][y]=corAtual; if x is negative here, it will seg fault here, as it is before the check to see if x > 0
