Exporting an TImage contents to WMF format

Problem/Question/Abstract:

How can I export the content of a TImage for an image in the format of Clip Galleyr of Microsoft Office?

Answer:

I used this function once and she worked.

procedure ExportBMPtoWMF(Imagem: TImage; Dest: Pchar);
//
// Export an TImage contents to WMF format (Microsoft Clippart format file)
//
var
  Metafile: TMetafile;
  MetafileCanvas: TMetafileCanvas;
  DC: HDC;
  ScreenLogPixels: Integer;
begin
  Metafile := TMetafile.Create;
  try
    DC := GetDC(0);
    ScreenLogPixels := GetDeviceCaps(DC, LOGPIXELSY);
    Metafile.Inch := ScreenLogPixels;
    Metafile.Width := Imagem.Picture.Bitmap.Width;
    Metafile.Height := Imagem.Picture.Bitmap.Height;
    MetafileCanvas := TMetafileCanvas.Create(Metafile, DC);
    ReleaseDC(0, DC);
    try
      MetafileCanvas.Draw(0, 0, Imagem.Picture.Bitmap);
    finally
      MetafileCanvas.Free;
    end;
    Metafile.Enhanced := FALSE;
    Metafile.SaveToFile(Dest);
  finally
    Metafile.Destroy;
  end;
end;
