Truxton file create exif

This creates an EXIF object sourced from this file that you can use in the EXIF API. An EXIF object is how you add records to the EXIF table. The resulting EXIF object will automatically be associated with the file it was created from and with the media the file belongs to.

Note: Not all camera information comes from EXIF sections. Camera information can be exploited from anywhere in the file but the meta data will be stored in the EXIF table.

Syntax

uint64_t truxton_file_create_exif( uint64_t file_handle );

Parameters

file_handle

The handle created by the truxton_file_open_id or truxton_file_open_md5 call.

Return value

A handle to an EXIF object.

Sample

void process_file(uint64_t truxton)
{
   uint64_t file = truxton_file_open_md5(truxton, "9ec8fb6095c35eff2b236863b7caaf10");

   uint64_t exif = truxton_file_create_exif(file);

   truxton_exif_set_make(exif, "Ford");
   truxton_exif_set_model(exif, "Mustang");
   truxton_exif_set_device_time(exif, truxton_file_get_modified( file ) );
   truxton_exif_set_latitude(exif, 27.94999);
   truxton_exif_set_longitude(exif, -82.354748);
   truxton_exif_save(exif);
   truxton_exif_destroy(exif);

   truxton_file_free(file);
