[libredwg] libredwg Parsing problem

[bjcj]

Dear：
  I am learning our libredwg. I don't find the layer relationship corresponding 
to the element in the parsed json data, such as which layer a certain line 
belongs to. Please help guide. Thank you!


{
      "entity": "LINE",
      "type": 19,
      "handle": "0.2.828",
      "size": 40,
      "bitsize": 302,
      "owner": "5.1.31",
      "start": [ 30666.462047, 31.762437, 0.000000 ],
      "end": [ 30666.462047, -1288.237563, 0.000000 ],
      "thickness": 0.000000,
      "extrusion": [ 0.000000, 0.000000, 1.000000 ]
    }
For example, the above data is a line obtained by parsing dwg. Which layer 
should it be in? How do I find the layer of this line?
