EXIF writting?

Hi was not able to find examples on geotagging photos. I know that the default bb10 camera has access to gps.

 

I that I would have to write the EXIF data using the built in library?

 

For instance 

 

The OnPhotoSaved function.

{

Get GeoLocation Data.

I would write the photo jpg with this information. // built using EXIF library.
Save the photo to the camera/shared

 

//GeoTagging complete?
}

 

 

Or is there a built in function to do this. I have searched the documentation and found nothing.

Re: EXIF writting?

Do you try toying around with the libexif library from this page?

Re: EXIF writting?

I have but I noticed that the bb10 camera by default has the geotagging, I was wondering if that was built into the camera api?

 

Or do I have to write this into the image file using this

 

http://libexif.cvs.sourceforge.net/viewvc/libexif/libexif/contrib/examples/write-exif.c?revision=1.3...

 

I would have hoped for better exif support on the camera, because now I have to figure out what needs to be written,

 

GPSLatitude      GPSLongitude      GPSAltitude          GPSDateStamp
GPSLatitudeRef   GPSLongitudeRef   GPSAltitudeRef       GPSTimeStamp
GPSTrack         GPSSpeed          GPSImgDirection      GPSPitch        
GPSTrackRef      GPSSpeedRef       GPSImgDirectionRef   GPSRoll I would assome thats all i need to write? how would I get access to these things via the location services ?


Another question I have is can I write my own data into the file perhaps add user comments and or tags? ?

Re: EXIF writting?

The camera service doesn't geotag the image for you, but you can provide it the data in the C API with camera_set_geolocation.

 

If you are using the Cascades API, yes, you would need to tag it with libexif.
