working with JitterObjects in mxj that don't output jitter matrices


    Oct 03 2007 | 10:15 am
    hi,
    i'm trying to write a class for mxj that incorporates a JitterObject.
    from the examples this seems to be straight forward for objects that
    process and output jitter matrices, like in the
    "javajitterfirsttest.pat" example, where jit.sobel and jit.brcosa are
    used with the "matrixcalc" message:
    mybrcosa.matrixcalc(inname,mymatrix2);
    etc.
    but what about using a jitter object, which doesn't output a jitter
    matrix?
    i'd like to find the mean value of a 2d 1 plane matrix using jit.3m e.g.
    JitterObject my3m = new JitterObject("jit.3m");
    my3m.matrixcalc(myInputMatrix, ???);
    thanks for any pointers.
    volker.

      same question but with jit.findbounds
      findbounds has two outlets which output list two integer lists
      how do i grab the output ?
      myfindbounds.matrixcalc(mat, ???);

      ok. i found this solution for js
      in java:
      my3m = new JitterObject("jit.3m");
      ...
      my3m.matrixcalc(inmat, null);
      outlet(1,"mean", my3m.getAttr("mean"));
      but with jit.findbounds it doesent work ;-(
      WHY NOT !!!
      because the jit.findbounds outlet name "min bound" has got a blank ?
      i tried als permutations "min bounds", "min_bounds", "minbounds"...
      and allways get an
      java.lang.NullPointerException: args argument cannot be null
      error message
      any ideas ?
