Dialogs, Menus, LEADTwain, LEADDlgService, LEADDlgFile, ExtCtrls,
LEADMain, StdCtrls, LEADDicom;
procedure TForm1.Button4Click(Sender: TObject);

NewCommentText: string; { String for CMNT_SZDESC that we read }
FilePath: string; { File to be updated }
i: Integer; { Counter }
nRet: Integer;
begin
{ Specify the file that we will update. }
FilePath := 'C:\Images\5.dcm';
{ Specify the Empty variant for clearing comments. }
VarClear(Empty);
{ Get all of the current comments from the file. }
{ Temporarily disable method errors so that we do not fail when comments are missing. }
LeadImage1.EnableMethodErrors := False;
for i := 0 to CMNT_LAST do
begin
LeadImage1.Comment[i] := Empty;
LeadImage1.Comment[i] := LeadImage1.ReadComment(FilePath, 0, i);
end;
LeadImage1.EnableMethodErrors := True;

MyCommentText := CHR(13) + 'This image has been reversed.';
LeadImage1.Comment[CMNT_SZDESC] := LeadImage1.Comment[CMNT_SZDESC] + MyCommentText;
{ Save the file and read the comment that we saved. }
LeadImage1.Save(FilePath, FILE_TIF, LeadImage1.BitmapBits, 0, SAVE_OVERWRITE);
NewCommentText := LeadImage1.ReadComment(FilePath, 0, CMNT_SZDESC);
