description Library for manipulating PNG images
long_description \
Libpng was written as a companion to the PNG specification, as a \
way to reduce the amount of time and effort it takes to support \
the PNG file format in application programs. Most users will not \
have to modify the library significantly, advanced users may want \
to modify it more. The library was coded for both users. All \
attempts were made to make it as complete as possible, while \
keeping the code easy to understand. Currently, this library \
only supports C. Support for other languages is being considered.
