Hi,

Is it possible to remove all GPS-related EXIF data from a jpg image? All other EXIF data could remain untouched and all GPS-related data could completely removed.

Thanks in advance.

Hi,
set EXIF_GPSVersionID='' and save back the image. Example:

ImageEnView1.IO.LoadFromFile('input.jpg');
ImageEnView1.IO.Params.EXIF_GPSVersionID := '';
ImageEnView1.Io.SaveToFile('output.jpg');

Hi,

Thanks. It does exactly what I need.
Does it intentional feature (I mean setting EXIF_GPSVersionID := '' deletes all GPS-related data) or it is accidental feature?
I'm asking because other GPS fields (e.g. EXIF_GPSLatitudeDegrees, EXIF_GPSLongitudeDegrees) did not touch just EXIF_GPSVersionID but all of them deleted.

Thanks.

This is intentional. Because GPSVersionID is necessary, when it is empty ImageEn doesn't save back other GPS tags.
