How to Use the class IntelliStampSpec?

I want to put a picture into the autovue  as a markup in API?

Autovue has a function IntelliStampSpec can Implement it?

So I want use API ,use IntelliStampSpec to Implement !

sample code:

 IntelliStampSpec iss = new IntelliStampSpec(m_markupbean.getMarkupEntitySpec(),new PAN_Rectangle(riqiPointX,riqiPointY+400,1000,1000),"uu");
        byte[] paramArrayOfByte = null;
        
        
         paramArrayOfByte = getByte("d:/bmp/uu.bmp");
 
  Debug.P(paramArrayOfByte);
  iss.setMetafileData(paramArrayOfByte);
  iss.setMetafileName("uu1");
        m_markupbean.setMarkupEntityClass(iss.getEntityClassName());
        iss.setMarkupLayer(m_markupbean.getActiveMarkupLayer());
        // Create the textBox
        m_markupbean.addMarkupEntity(iss);

The markup file is Generated,Open the file by autovue. The markup generated,but the picture not display??? why??
