[Lcms-user] sRGB to Lab change of behaviour in 2.4

[Lukas J. <l.j...@gm...>]

Hello,
did the behaviour of conversion from sRGB to Lab changed in the lcms 2.4?

After update to 2.4 I get different results from what I used to get
with older lcms versions. The values used to be somewhere in range
[0,1], but now the values seems to be in range [0-100?].

For example, assume the conversion conversion from uint8 sRGB:
{63, 63, 63}
to Lab float.

With older lcms versions I got:
{0.275746, 0.502007, 0.501945}
but now I get:
{27.5745792, 0.0116731515, -0.00389105058}

Is this change intentional?

The profiles are created using the cmsCreate_sRGBProfile() function
for RGB and cmsCreateLab4Profile(0) for Lab.

Regards,
Lukas
