%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.
