Product     : Fedora 15
Version     : 1.2.46
Release     : 2.fc15
URL         : http://www.libpng.org/pub/png/
Summary     : A library of functions for manipulating PNG image format files
Description :
The libpng package contains a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.  PNG
is a bit-mapped graphics format similar to the GIF format.  PNG was
created to replace the GIF format, since GIF uses a patented data
compression algorithm.

Libpng should be installed if you need to manipulate PNG format image
files.
