I then try to save the tag with this: Yes, DMS (three rational numbers) is what the Exif standard specifies as input for these tags, so that is what PEL supports. We should probably support decimal format as well. > $lon = new PelEntryRational(PelTag::GPS_LONGITUDE, > array($degree,1), array($minute,1), array($second,1)); > > This works to an certain extent, but I'm not able to save the seconds > with decimals (which I need to get an accurate result).

Why is that? Isn't it > possible to use decimals here? I am not entirely sure, but are you saying that you use a floating point number in the $seconds variable used above? It must be an integer since you are constructing a rational number with the array construct: "array($x, $y)" is the rational number "$x/$y", where $x and $y are both integers. Have you seen this file, which is only available with a SVN version: http://pel.svn.sf.net/viewvc/*checkout*/pel/trunk/examples/gps.php I hope it might be related to what you are trying to do. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multi-Party Computation) to Python.
