binary matrix compression

I am trying to compress a matrix made only of zeroes and ones, any suggestions?

import com.cycling74.max.*;
import com.cycling74.jitter.*;

public class m_runlenght extends MaxObject
{
    private int  dalist[];
    private JitterMatrix ciccio;
    private int dimArray[];
    private    int contaR;
    private    int contaC;
    private int contaUg = 1;
    private int contaElem = 0;
    private int contaRows = 0;
    private int memo = 0;
    private int val[]= new int[1];
    private int matIn[];
    private int theRows = 8;
    private int matOut[];

    private static final String[] INLET_ASSIST = new String[]{
        "inlet 1 Feed with a binary matrix (0-255)"
    };
    private static final String[] OUTLET_ASSIST = new String[]{
        "outlet 1 run-lenght compressed list"
    };

    public m_runlenght(Atom[] args)
    {
        declareInlets(new int[]{DataTypes.ALL});
        declareOutlets(new int[]{DataTypes.ALL});

        setInletAssist(INLET_ASSIST);
        setOutletAssist(OUTLET_ASSIST);
        dalist= new int[255];
        ciccio = new JitterMatrix("compre",1,"long",255,theRows);
        matIn  = new int[320*240];
        matOut = new int[255*theRows];
    }

    public void jit_matrix(String inname)
    {
        contaUg = 1;
        contaElem=0;
        contaRows=0;
        JitterMatrix foo = new JitterMatrix(inname);
        foo.copyMatrixToArray(matIn);
        ciccio.setall(Atom.newAtom(0));
        ciccio.copyMatrixToArray(matOut);
        for (contaR = 0 ; contaR < 240*320; contaR++){
            if (contaRows
