C++ interface to the PNG (Portable Network Graphics) library
PNG++ aims to provide simple yet powerful C++ interface to libpng, the Portable Network Graphics (PNG) reference implementation library.
Using raw libpng in C++ may impose serious challenge since lots of precautions must be taken to handle initialization/deinitialization of control structures as well as handling errors correctly. With png++ you can read or write PNG images just in a single line of C++ code.
