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.
