Module documentation for 1.0.1

This package contains pure Haskell parsers for the netpbm image formats: PBM, PGM and PPM, for both ASCII and binary encodings.

All netpbm image formats are implemented (P1 - P6).

The current implementation parses PPM images at around 10 MB/s on a Core i5-2520M.

CHANGELOG

Version 1.0.1

  • Added required Vector imports necessary for deriving Unbox instances.

Version 1.0.0

  • Use storable instead of unboxed vectors to allow easier integration with Ptr based APIs.
