property EXIF_UserComment: WideString

Example

// Write our comment to the file
ImageEnView1.IO.LoadFromFile('C:\input.jpg');
ImageEnView1.IO.Params.EXIF_UserComment := 'Hello World!';
ImageEnView1.IO.Params.EXIF_UserCommentCode := IEEXIFUSERCOMMENTCODE_UNICODE;
ImageEnView1.IO.Params.EXIF_HasEXIFData := true;
ImageEnView1.IO.SaveToFileTIFF('D:\test.tiff');

// Read back the comment
ImageEnView1.IO.LoadFromFileTIFF('D:\test.tiff');
ShowMessage( ImageEnView1.IO.Params.EXIF_UserComment );
