README
Exexif
Read TIFF and EXIF information from a JPEG-format image.
Retrieve data from a file:
iex> {:ok, info} = Exexif.exif_from_jpeg_file(path)
Retrieve data from a binary containing the JPEG (you don't need the whole thing—the exif is near the beginning of a JPEG, so 100k or so should do fine).
iex> {:ok, info} = Exexif.exif_from_jpeg_buffer(buffer)
Access the high level TIFF data:
iex> info.x_resolution
72
iex> info.model
"DSC-RX100M2"
The exif data is in there, too.
iex> info.exif.color_space
"sRGB"
iex> info.exif |> Dict.keys

GPS data is in there, too (if presented in EXIF, of course.)
iex> {:ok, info} = Exexif.exif_from_jpeg_file("test/images/sunrise.jpg")

iex> info.gps.gps_latitude
