Source code changes of the file "src/tmo/fattal02/pfstmo_fattal02.cpp" between
pfstools-2.1.0.tgz and pfstools-2.2.0.tgz

About: pfstools are a set of command line programs (and one GUI program) for reading, writing, manipulating, and viewing high-dynamic range (HDR) images and video frames (similar as the netpbm package does for low-dynamic range images).
