Exif serialization and deserialization

Development

To run the tests for this library, the git submodule exif-samples must be checked out.

To do that run the following in this repository:

git submodule update --init

You can also clone this repository recursively:

git clone --recursive https://github.com/vadixidav/exifsd.git

Credits

This excellent overview of the Exif file format was incredibly useful in the development of this library. Big thanks to TsuruZoh Tachibanaya!

This overview helped in identifying JPEG markers.

Wikipedia was useful in parsing entopy-encoded data.

This seems to be mostly the same as the one by TsuruZoh Tachibanaya, but it provides some slight variation and is more compact.

This page contains a list of various metadata markers in JPEG files.
