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

getFileType "/tmp/mystery_file"

Just "webp"

Or to test for a specific extension:

isPgm "/tmp/file.pgm"

True

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

["file2.jpeg","file1.jpeg"]

Supports the following extensions: JPEG, PNG, GIF, TIFF, RGB, PBM, PGM, PPM, RAST, XBM, BMP, WebP, EXR.

Depends on:

base, bytestring
