haskell@gentoo.org Gentoo Haskell This package is written in 100% Haskell and enables you to write PPM (\"Portable Pixel Map\") images in human-readable text format as well as the more efficient binary format. It uses the ByteString library for maximum efficiency. For those that don't know, PPM is an image file format which is trivially simple, but therefore horribly inefficient. None the less, many programs can read PPM files, so this package represents an easy way to write Haskell code that generates images, without having to depend on any external C code.
