In CinePaint is an device link file based caching implemented.

Naturally not all options are available with device links.
Once You use device links, will be bound by them or You have to create
exceptions.
Would an transform cache fit in an global memoy space? This using

If you mean caching pixels in a transform, no. There is a
one-pixel cache already implemented. If you mean caching yet existing
color transforms... hard to say. A transform can take a lot of
applications. Sometimes
they call it matteing.

Hi,

So I would interprete Your ideas as: an device link handling system
(used by all applications, which want to share the transforms) is
essential to set up and run such cache, without interfering from
application side - correct?
(I must say, I did not yet play with mmap-ing)

Hi,
I'm currently making Krita, the KOffice image app, use littlecms for
everything color related, and I'm having a few questions...

I've been experimenting, and I definitely need to cache at least some
transforms. It turns out to be prohibitively slow to recreate the transform

Can You describe the display
