LCMS 2.8 will handle alpha channels

The LCMS 2.8 release candidate 1 has code for handling alpha channels during ICC profile conversions:

"2.8 does support alpha channel transportation and a new transform stride function and plug-in which can be used to increase significantly the processing speed."

Perhaps this new code could be useful for helping GIMP make faster ICC profile conversions? As there are a lot of profile conversions going on with some of the new color management code, probably every little bit helps.

Here's the link to the announcement and discussion:

That is great news :)

We will definitely make use of that, do you know when it will be available? We will clearly depend on lcms 2.8 if it becomes available before GIMP 2.10.

No, I don't know a firm date. It depends on feedback. But based on past experience, the time between the first release candidate and the final release is usually not too long - weeks, not months.
