Hi Michel,

I have changed the file entifgr.pas like described, compiled. I have changed the files EnTifGr.dcu, En_D4.dcu, En_D4.dcp, En_D4.bpl. But the result is the same.

procedure TForm1.Button1Click(Sender: TObject);
var
DestGraphic : TTiffGraphic;
i, j: longint;
begin
j := ImageScrollBox1.ImageCountFromFile(FilenameEdit1.FileName);
ImageScrollBox1.LoadFromFile(FilenameEdit1.FileName, 0);
DestGraphic := TTiffGraphic.Create;
DestGraphic.Compression := tcGroup4;
DestGraphic.Assign(ImageScrollBox1.Graphic);
DestGraphic.RowsPerStrip := 4294967295;
DestGraphic.SaveToFile(FilenameEdit1.FileName + '.TIF');
for i := 2 to j do begin
ImageScrollBox1.AppendToFile(FilenameEdit1.FileName + '_neu.TIF');
end;
end;

Can you advice?

Best regards,

Peter
