VOID Example_GetMetafileHeader1(HDC hdc)
{
   Graphics graphics(hdc);

   // Create a Metafile object from an EMF+ file.
   Metafile metafile = new Metafile(L"file1.emf+");

   // Create a MetafileHeader object.
   MetafileHeader metaHeader;

   // Get the MetafileHeader.
   metafile->GetMetafileHeader(L"file1.emf+", &metaHeader);

   // Get the bounding rectangle of the metafile.
   Rect rect;
   metaHeader.GetBounds(&rect);

   // Create a Pen object, and draw the bounding rectangle.
   Pen pen(Color(255, 0, 0, 0));
   graphics.DrawRectangle(&pen, rect);

   // Delete the metafile.
   delete metafile;
}
