Hi,

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls;

type
  TForm1 = class(TForm)
    Bit: TImage;
    Beenden: TButton;
    Button1: TButton;
    procedure MakeRed(Bit: TBitmap);
    procedure BeendenClick(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;


implementation

{$R *.dfm}

procedure TForm1.MakeRed(Bit: TBitmap);
type
  PixArray = Array [1..3] of Byte;
var
  p: ^PixArray;
  h,w: Integer;
begin
  For h:=0 to Bit.Height-1 do
  begin
    p:= Bit.ScanLine[h];
    For w:=0 to Bit.Width-1 do
    begin
      p^[3]:=255;
      Inc(p);
    end;
  end;
end;

procedure TForm1.BeendenClick(Sender: TObject);
begin
close;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  MakeRed(Bit: TBitmap);
end;

end.

Fehlermeldung :
