API & Example

You may provide either a String specifying the path to the image or a Buffer containing the image data and you will receive an object with 'height' and 'width' properties on your callback

var sz = require('sz')
  , fs = require('fs')
 
sz('/path/to/nyancat.gif', function (err, size) {
  // where `size` may look like: { height: 280, width: 400 }
})
 
var buf = fs.readFileSync('/path/to/nyancat.gif')
 
sz(buf, function (err, size) {
  // where `size` will be the same as above
})
