  45  <p>
  46  An icon can either be created from an arbitrary image file (type is determined by the file extension) or it can also be one of the builtin icons. The builtin icons are:
  47  <ul>
  48  <li>GICON_WARNINGRED
  49  <li>GICON_TEXT
  50  <li>GICON_ENDCONS
  51  <li>GICON_MAIL
  52  <li>GICON_STARTCONS
  53  <li>GICON_CALC
  54  <li>GICON_MAGNIFIER
  55  <li>GICON_LOCK
  56  <li>GICON_STOP
  57  <li>GICON_WARNINGYELLOW
  58  <li>GICON_FOLDEROPEN
  59  <li>GICON_FOLDER
  60  <li>GICON_TEXTIMPORTANT
  61  </ul>
  62  <p>
  63  A graphic illustration of the differenmt icons can be found in the manual.
  64  <p>
  65  The second argument specifies an optional scaling factor for the image/builtin icon.
  66  <p>
  67  The icons are then used exactly as you would use text strings when specifying a title for the gantt object. For example:
  68  <code>
  69  $icon = new IconImage(GICON_WARNING,0.7);
  70  $titles = array($icon,'65 days','3 Aug','5 sep');
  71  $bar = new GanttBar(0,$titles,$startdat,$enddate);
