Deep Zoom support via sharp

[lovell]

Hello @gasi, @aseemk, I know you're relatively happy users of sharp/libvips and now I've just discovered you maintain this rather useful module too!

I'm looking for some help testing sharp's forthcoming native support for Deep Zoom output. You can find this in the judgement work-in-progress branch that will form v0.10.0.

npm install lovell/sharp#judgement

The Deep Zoom API is accessed via the tile method and the use of a .dzi file extension, for example

sharp(input).tile(size, overlap).toFile('output.dzi', function(err, info) { ... });

Might this be a feature of sharp that this module could take advantage of?

@lovell Your API looks great and yes, I think this would be super valuable. I haven’t worked on node-deepzoomtools in a while and this is a good reminder that sharp will work much better than manually calling vips through the shell! I can’t make promises if or when I’ll work on this again but when I do, I’ll tackle this.

Awesome @lovell — agreed, great API!

I too am a bit busy with other stuff at the moment, but we'll see if one of us can take a stab at some point. /cc @iangilman too. =)
