[Lcms-user] Lab to RGB conversion

[Aaron B. <bo...@gm...>]

Hello!
This isn't strictly an lcms question, but I was wondering if anyone here
can give me some insight into a few lines of code I've inherited in my
project that use
lcms to convert Lab to RGB:

https://github.com/GrokImageCompression/grok/blob/master/src/bin/common/color.cpp#L742

This code works for 8 bit Lab but not for 16 bit and I am trying to fix
this. I am particularly wondering about the three constants 100, 170 and
200.

Any insight would be greatly appreciated.
Thanks!
Aaron
