RE: [Lcms-user] How to convert RGB in some ICC profile to LAB

[Boris L. <b.l...@gm...>]

First thanks for answer.

I found in description of sRGB matrix which convert sRGB to XYZ and in
your source is method how to convert XYZ to LAB. Is it good solution?
Because I don't want to distribute these big ICC profiles with my
application.

BTW in libmng I found function how to create sRGB profile in memory so
it is IMHO good to include this function in lcms API also.
