image-type: Determine the type of an image by reading the first bytes.

[ bsd3, graphics, library ] [ Propose Tags ]

A package used to determine the type of an image according to its first bytes based on the Python library imghdr.

Most simplest usage is getting the type of a file:

>>> import Codec.ImageType

Just "webp"

Or to test for a specific extension:

>>> isPgm "/tmp/file.pgm"
>>> import qualified Data.ByteString as B
>>> testPgm <$> B.readFile "/tmp/file.pgm"
Just "pgm"

Or to filter files by extension:

>>> import Codec.ImageType
>>> import Control.Monad
>>> import System.Directory
>>> getDirectoryContents "." >>= filterM doesFileExist >>= filterM isJpeg
