Detailed Description

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

There are two implementations of this functor.

• The first one uses the C++ JPEG 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/jpeg/00readme.txt for more information. If the file ltiJPEGFunctor.cpp and the directory jpeg/ are found in ltilib/src/io, and HAVE_LIBJPEG is not defined in basis/ltiConfig.h, this will be the implementation used.

• The second implementation uses the standard JPEG 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 ltiJPEGLibFunctor.cpp). The autoconf script (./configure) will automatically detect if you have the libjpeg installed, and activate this implementation if possible. (see http://www.ijg.org/files/ and http://freealter.org/doc_distrib/libgr-2.0.13/jpeg/Libjpeg.html)

We recomend to use the libjpeg, it is more robust against not 100% correct JPEG-files, and it is faster. Mianos' implementation is mainly for windows users who do not want to install the jpeglib.
