restrict width and height on mop initialization

    May 31 2012 | 7:32 pm
    Hello, I would like to create a mop with 0 input and 1 output and restrict the matrix info to be "4 char 640 480".
    How can I restrict the matrix width and height?
    in order to set the type and planecount I use jit_mop_single_type and jit_mop_single_planecount. it seems like there is no such utility function for the dimensions.
    I tried:
    p = jit_object_method(mop, _jit_sym_getoutput, 1);
    m = jit_object_method(p, _jit_sym_matrix);
    jit_object_method(m, _jit_sym_getinfo, &info);
    jit_attr_setlong_array(&info, _jit_sym_dim, 2, dims);
    but m returns null.
    I also saw _jit_sym_restrict_dim symbol used in jit_mop_ioproc_copy_adapt method, but I don't know how I could use that when assigning width and height from scratch.
    Any suggestions? Thanks a lot

      The solution I eventually found is to use _jit_sym_mindim and _jit_sym_maxdim methods like this:
      void *p, *m;
      t_atom args[4];
      jit_atom_setlong(args, 640);
      jit_atom_setlong(args + 1, 480);
      p = jit_object_method(mop, _jit_sym_getoutput, 1);
      jit_object_method(p, _jit_sym_mindim, 2, &args);
      jit_object_method(p, _jit_sym_maxdim, 2, &args);
