Answer 1

如果用程序来转真的有点高难了，
如果我没有记错的话，AutoCad有一个导出功能，可以导出为图片格式！

try
                     cad:=CreateoleObject('AutoCAD.Application');
                  except
                     on E:Exception do
                     begin
                        // common.SAVE_DO_LOG(common.username,'CAD调用出错:'+e.Message,err_log);
                         Application.MessageBox( 'CAD调用出错','信息提示',MB_OK+ MB_ICONINFORMATION);
                         exit;
                     end;
                  end;
                       cad.Visible:=true;
                       caddoc:=cad.ActiveDocument;
                      // cad.ZoomAll;
                      //改变当前背景颜色为白色
                       cad.Preferences.Display.GraphicsWinModelBackgrndColor:= clwhite;
                     //改变当前命令行为1行
                       cad.Preferences.Display.DockedVisibleLines:= 1;
                     //设置模式为单文档
                       caddoc.SetVariable('SDI',1);
                       caddoc.Application.Documents.Open('c:\ff.dwg', False);
                       sleep(1000);
                       t_SelectionSet:=caddoc.SelectionSets.Add('1');
                       t_SelectionSet.Select(5);
                       caddoc.Export( 'c:\test', 'WMF', t_SelectionSet);
