libpng12-config	provides configuration information for libpng.
libpng.so and libpng12.{so,a}	are a collection of routines used to create and manipulate PNG format graphics files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions and lack of patent problems.
