xyzToCieLab bug #197

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
While implementing the 1994 DeltaE formula for CIE Lab color differencing, I 
found a bug in the f and finv functions in ErrorMetric.cpp. The test against 
epsilon was reversed. I'm using the math from: 
http://www.brucelindbloom.com/Eqn_XYZ_to_Lab.html as a reference.

Attached is a patch with just this bug fixed.
