如何读取图上的文字信息？

• 回答：

  代码实现如下：

  
  

  MrxDbgSelSet ss = new MrxDbgSelSet();
  ss.allSelect();
  for(int i = 0; i <ss.size();i++)
  {
      long lId = ss.at(i);
  
      McDbEntity ent = new McDbEntity (lId);
  
      // 得到对象的层名.
      Log.e("LayerName",ent.layerName());
  
      String sName =  MxFunction.getTypeName(lId);
  
       if(sName.equals("McDbText"))
      {
          McDbText txt = new McDbText(ss.at(i));
      
          McGePoint3d pos = txt.position();
      
          String sTxt = txt.textString();
          double dH = txt.height();
      
          String sT;
          sT = String.format(" pos:%f,%f,Txt:%s,H:%f",pos.x,pos.y,sTxt,dH);
      
          Log.e("McDbText",sT);
      }
