Putting Bitmap data into a "pas" file...

How can I store some bitmaps in my "pas" unit without creating a "res" file? I've a quite big utility unit which just needs 2 or 3 bitmaps. And I would really like to save this "res" file.
A little example would be great. Can I perhaps somehow copy the bitmap data from the "View form as text" option?

Thanx, Madshi.

Hi friend,
Here is how to do what you want, simply paste it to your implementation section, put a button on form and link Button1Click with the code. Regarding converting file data to pascal I use the Hex Workshop which is a commercial hex file editor. It can convert the selected block to a comma delimited array. But the programmer on your level has no trouble to write such a conversion routine. The bitData contains the all binary data from the C:\Program Files\Borland\Delphi 3\Images\ICONS\CHEM16.BMP.

implementation

{$R *.DFM}

const
 bitData : array[0..247] of byte = (
$42, $4D, $F8, $00, $00, $00, $00, $00, $00, $00, $76, $00, $00, $00, $28, $00,
$00, $00, $10, $00, $00, $00, $10, $00, $00, $00, $01, $00, $04, $00, $00, $00,
$00, $00, $00, $00, $00, $00, $12, $0B, $00, $00, $12, $0B, $00, $00, $00, $00,
$00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $00, $80, $00, $00, $80,
$00, $00, $00, $80, $80, $00, $80, $00, $00, $00, $80, $00, $80, $00, $80, $80,
$00, $00, $7F, $7F, $7F, $00, $BF, $BF, $BF, $00, $00, $00, $FF, $00, $00, $FF,

$50, $00, $00, $55, $55, $55, $00, $00);

procedure TForm1.BitBtn1Click(Sender: TObject);
var
  F : TMemoryStream;

begin
  F := TMemoryStream.Create;
  F.Write(bitData[0], sizeof(bitData));
  F.Seek(0,0);
  try

    try
      B.LoadFromStream(F);
      Canvas.Draw(0,0,B);
    finally
      B.Free;
    end;
  finally
    F.Free;
