Detailed Description

Base class to functors which load and save images in PNG format.

There are two implementations of this functor.

• The first one uses the C++ PNG interface from Miano (at Colosseum Builders C++ Image Library), for which several files are required. These are published under another licence and therefore are not included in the default LTI-Lib. You can use them in non-commercial applications and get them from ltilib.sourceforge.net. See file ltilib/src/io/png/00readme.txt for more information. If the file ltiPNGFunctor.cpp and the directory png/ are found in ltilib/src/io, and HAVE_LIBPNG is not defined in basis/ltiConfig.h this will be the implementation used.

• The second implementation uses the standard PNG Library, which is usually installed in all Linux distributions, but not for Windows. The implementation is included in the standard LTI-Lib, (file is called ltiPNGLibFunctor.cpp). The autoconf script (./configure) will automatically detect if you have the libpng installed, and activate this implementation if possible.

We recomend to use the libpng, it is more robust against not 100% correct PNG-files, and it is faster. Mianos' implementation is mainly for windows users that do not want to install the pnglib.
