ImageEnView1.IO.ParamsFromFile('D:\one.jpg');

// removes EXIF info from image.jpg
ImageEnView1.IO.Params.EXIF_HasExifData := false;
ImageEnView1.IO.InjectJpegEXIF('D:\image.jpg');

// Update the GPS EXIF data in a file
io := TImageEnIO.create(nil);
try
  io.ParamsFromFile( FilenameStr );

  io.Params.EXIF_GPSLatitude := GPSLatitudeFloat;
  io.Params.EXIF_GPSLongitude := GPSLongitudeFloat;
  io.Params.EXIF_GPSVersionID := GPS_Version_ID;

  io.InjectJpegEXIF( FilenameStr );
