Docs: include more info and sample images about resize kernels
@lovell, I've seen several issues where you've answered by suggesting the use of a specific kernel for various use cases, but I don't have a very good understanding of what each one does at a high level.
It would be really great if the documentation provided some rough guidance on the various kernels, explaining briefly what the primary use case is for each, and discussing the tradeoffs involved. I'm thinking really simple, quick bullet points like "The X kernel is fast, but sacrifices quality. It's great for line drawings, but not very well suited for rich photos, etc."
BTW, thanks for this really impressive lib!
Yes, good idea, this should probably also include sample images demonstrating the effect each has on things like high contrast diagonal edges.
There's currently a PR to add sample images to demonstrate the fit option at https://github.com/lovell/sharp/pull/3350 and the kernel option should probably take a similar approach.
Happy to accept a PR with a similar update, if you're able.
@lovell , I would love to be able to contribute a PR here, but I'm afraid the reason I'm asking for it is that I simply don't have this knowledge to begin with. 😄
