A new package called `pixmap' has been released on CRAN. From the
DESCRIPTION file:

Package: pixmap
Version: 0.2-1
Title: Bitmap Images (``Pixel Maps'')
Depends: R (>= 1.3)
Author: Friedrich Leisch and Roger Bivand
Maintainer: Friedrich Leisch <Friedrich.Leisch@ci.tuwien.ac.at>
Description: Functions for import, export, plotting and other
  manipulations of bitmapped images.
License: GPL version 2.

The package is intended to provide the central low-level support for
reading/writing/plotting bitmapped images. It replaces the read.pnm
and write.pnm functions of package e1071. Currently only PNM images
are supported for import/export, but we want to add other filter real
soon.

A rich class structure is already in place, allowing for grey, rgb and
indexed images together with conversions between all three
formats. The classes allow images also to have a coordinate system
attached, such that, e.g., locator() can be used meaningfully on
geographical maps.

This is a first release, all comments and feedback are more than
welcome (thanks to Jonathan Marchini for valuable feedback on the
first development version).

Best,
Fritz Leisch
