An exif parsing library in pure haskell.
You can check the api docs on the hackage page: http://hackage.haskell.org/package/hsexif
The license is BSD3.
When building on windows if you have trouble with the iconv
library you can also build without it. That way you loose nice decoding of the EXIF user comments though.
cabal install -f-iconv
NB: the test images were also modified with exiv2 -M"set Exif.Photo.UserComment charset=Unicode Test Exif commentčšž" test.jpg to get user comments.
