def testFormat():
    infile = dataDir + "Ref_Gold.segy"
    ais = ArrayInputStream(infile)
    ais.skipBytes(nhead + nbhed)
    ais.skipBytes(nthed)
    xi = zeroint(n1)
    ais.readInts(xi)
    ais.close()
    x1 = zerofloat(n1)
    x2 = zerofloat(n1)
    Convert.ibmToFloat(xi, x1)
    Convert.ieeeToFloat(xi, x2)
    SimplePlot.asPoints(x1)
    SimplePlot.asPoints(x2)

Example #2

  ais = ArrayInputStream(infile)
  ais.skipBytes(nhead+nbhed)
  ais.skipBytes(nthed)
  xi = zeroint(n1)
  ais.readInts(xi)
  ais.close()

  x2 = zerofloat(n1)
  Convert.ibmToFloat(xi,x1)
  Convert.ieeeToFloat(xi,x2)
