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. The library is available as 32-bit and 64-bit. The library contains older versions. This version has been compiled with GCC.
