Zugriffsverletzung bei Constructor.Create

[Die Muhkuh]

Das hier:

Delphi-Quellcode:

constructor TPixelField.Create(Width, Height : Integer);
Var i : Integer;
begin
  SetLength(Pixels, Width);
  for i := low(Pixels) to high(Pixels) do
    SetLength(Pixels[i], Height);
end;

könnte man doch noch so abkürzen:

Delphi-Quellcode:

constructor TPixelField.Create(Width, Height : Integer);
begin
  SetLength(Pixels, Width, Height);
end;
