among the 1.8seconds using time, about 0.8 seconds are contributed by Interpolations
/CoordinationTransformations
/StaticArrays
, so it definitely worth if we can skip loading them; especially it will be more convenient if we can make ImageShow always loaded with the better restrict
implementation.

@timholy how do you think of moving restrict
to ImageCore
? That way ImageShow
could also benefit from this.

I'm supportive of the idea of splitting it out but a bit reluctant to move it to ImageCore, simply because there are no other "algorithms" in there: it's all traits and views.
We could make a separate ImageUtils package and put it there. We could also split out a subpackage from this one and register it separately, e.g., ImageTransformationsRestrict
, and it could continue living here. Other thoughts?

Haven't tried it out, but perhaps we could take advantage of https://github.com/JuliaPackaging/Preferences.jl to come up with a way to lazily compile the module, i.e., if we only need a function, then only compile related parts?

It's been a while since I opened this issue.. and load time (and precomp time) has, as expected, improved with 1.6
julia> @time using ImageTransformations
1.839368 seconds (3.92 M allocations: 285.683 MiB, 4.28% gc time, 18.44% compilation time)
I'm not too worried anymore, but don't let that stall the idea if you think it's still worth it
from imagetransformations.jl.
I plan to make ImageUtils
on top of ImageCore
, and then move restrict
there.
Because the main purpose of ImageUtils
is to boost loading time, it needs to be very conservative to dependencies outside JuliaImages.
