[xmkevin]

Hi, is there any plan for developing an node bindings ?

thanks.

Not that I know of. If you or anyone else would like to do it, I'm sure the community would be interested in using them! I'd be happy to answer implementation-related questions on the openslide-users mailing list.

Thanks. I have subscribed the mailing list. Since I don't familiar with c++, I will try my best to implement one.

Reopening to keep a record of the request.

I don't know if it would fit your needs, but sharp supports openslide file read:

https://github.com/lovell/sharp
http://sharp.dimens.io/en/stable/

It'll let you pull out areas from specific layers and render to jpg/png/whatever, in a buffer, stream or file. It has a nice, fluent, promise-based API and is well supported on Linux, macOS and Windows. It's just npm install sharp to get started, though you may need to enable openslide support, depending on your platform.

It includes things like pyramid generation for seadragon/zoomify/gmaps too, which can be useful.

@jcupitt Thanks. What we need is to read the existing vendor independent file formats, sharp doesn't support this.

[jcupitt]

@xmkevin, sharp can read all the formats that openslide can read, you just need to enable openslide support. There are some notes in the README.

@jcupitt Thank you very much. I will try sharp. Thanks again.
