Hi Peter

Please use:

ImageEnVect1.RemoveAllObjects();
ImageEnVect1.ClearAll();

Hello Nigel,

here my way for more understanding

Button one ( load Picture A.jpg ) and wenn exist A.iev


ImageEnVect1.IO.LoadFromFile('A.jpg');

if FileExists('A.iev') then
begin
ImageEnVect1.LoadFromFileIEV('A.iev');
end;



Button two ( load Picture B.jpg ) and wenn exist B.iev


ImageEnVect1.IO.LoadFromFile('B.jpg');

if FileExists('B.iev') then
begin
ImageEnVect1.LoadFromFileIEV('B.iev');
end;


the proplem is wenn not exist B.iev then is the follow loaded

B.jpg and A.iev

a clear all objects is not a solution


best regards
peter

Sorry I'm not following. Why not just use:

if FileExists('B.iev') then
begin
  ImageEnVect1.IO.LoadFromFile('B.jpg');
  ImageEnVect1.LoadFromFileIEV('B.iev');
end;

OK, so why not use

procedure TForm1.btn_load_jellyClick(Sender: TObject);
begin
  if FileExists(ExtractFilePath(Application.exename) + 'jelly.jpg') then
  begin
    ImageEnVect1.RemoveAllObjects();

      // load the bitmap
    ImageEnVect1.IO.LoadFromFile(ExtractFilePath(Application.exename) + 'jelly.jpg');

      // look for vectorial objects
    if FileExists(ExtractFilePath(Application.exename) + 'jelly.iev') then
    begin
      ImageEnVect1.LoadFromFileIEV(ExtractFilePath(Application.exename) + 'jelly.iev');
    end;
  end;
end;

procedure TForm1.btn_load_flowerClick(Sender: TObject);
begin
   if FileExists(ExtractFilePath(Application.exename) + 'flower.jpg') then
  begin
    ImageEnVect1.RemoveAllObjects();

      // load the bitmap
    ImageEnVect1.IO.LoadFromFile(ExtractFilePath(Application.exename) + 'flower.jpg');

      // look for vectorial objects
    if FileExists(ExtractFilePath(Application.exename) + 'flower.iev') then
    begin
      ImageEnVect1.LoadFromFileIEV(ExtractFilePath(Application.exename) + 'flower.iev');
    end;
  end;
end;
