![]() Date fields are returned as DateTime structures, GPS coordinates are wrapped with custom GPSLatitudeLongitude classes, etc. For ease of use, this Exif library converts Exif tags to either. The ExifData class reads the APP1 section, and extracts all Exif tags and also the embedded thumbnail (if any). To extract Exif metadata from a JPEG/Exif image, create an instance of the ExifData class with the path to the image file. If you are looking for a complete Exif metadata library, you may like to take a look at the excellent ExifTool Perl library by Phil Harvey. This library currently does not understand the vendor specific MakerNote tag. Hence, I decided to write my own Exif metadata utility, and this library was born. The framework reads the standard Exif tags, but it returns unprocessed raw bytes. NET Framework has some support for Exif metadata, it is not very user-friendly. I took many pictures along the way, and when I got back home, I wanted to write a small utility to tag the pictures with geo location information from my GPS. During my last summer vacation, I used a GPS navigation device while traveling the western coast of Turkey.
