How to get tiles into stream?

[pzien]

tile() method seems to return original image and dzi files and folder (or the zip file) seem to be a side effect of the call. How can I get the tiles without writing them to disk?
It would be nice to use it like that:

var transformer = sharp().tile();
readableStream.pipe(transformer).pipe(writableStream);

to get tiles into writableStream.

Hello, libvips only supports writing image pyramid tiles to disk.

I checked the relevant docs and they currently say "You can also use the file extension .zip or .szi to write to a ZIP container instead of the filesystem." This is confusing as the filesystem is still involved with ZIP output, sorry about that, I'll update this to be more explicit.

That's a pity... Thanks for a quick response!

Commit 4b98dbb hopefully removes some of the ambiguity from the docs - thanks for bringing this to my attention!

@lovell Does the situation change? I want to use Sharp in AWS Lambda to generate tiles from image around several GBs and upload to S3, but either /tmp (512MB at max) or memory (3GB at max) is limited.

Yes, please see #2238
