This retrieves the longitude portion of the WGS84 coordinates of where the media was seized.
This corresponds to the [Longitude] column of the [Media] table.
Syntax
double truxton_media_get_longitude( uint64_t media_handle );
Parameters
media_handle
The handle created by the truxton_media_open_id or truxton_media_create call.
Return value
The longitude portion of the geographic coordinate using the WGS84 ellipsoid of where this media was seized.
Sample
void has_location( uint64_t media )
{
double latitude = truxton_media_get_latitude( media );
double longitude = truxton_media_get_longitude( media );
if ( latitude != 0.0 and longitude != 0.0 )
{
printf( "The media was seized somewhere\n" );
}
else
{
printf( "We don't know where this media came from\n" );
}
}
