Nice Module but i can' use Buffer directly

[xelaz]

Hey,

you have nice Module, but i can't use Buffer as File(path) directly.

import calipers from 'calipers';

const Calipers = calipers('png', 'jpeg');

express.post('/upload', function(req, res) {
  // this is my Buffer of my uploaded file
  Calipers.measure(req.files.image.data).then(...).catch(...);
});

Or if i have Stream and i get the Buffer.

The Problem is, that image-size show me wrong sizes. And i was trying your module but i can't use it without Buffer interface :(

This isn't something we've added because its usually best to keep large image files on disk rather than in memory where they can end up consuming a lot of RAM.

This is a good suggestion though, I'm sure there are situations in which dealing with a buffer would be preferred.

Adding support for this for the image formats should be fairly straight forward as they load the file into a buffer from the get-go anyway. Adding support for PDFs might be a bit more complicated because it relies on Poppler and poppler-simple which doesn't support Buffers at this time.
