image-size
A Node module to get dimensions of any image file
Supported formats
- BMP
- GIF
- JPEG
- PNG
- PSD
- TIFF
- WebP
- SVG
- DDS
Upcoming
- SWF
Programmatic Usage
npm install image-size --save
Synchronous
var sizeOf = require('image-size');
var dimensions = sizeOf('images/funny-cats.png');
console.log(dimensions.width, dimensions.height);
Asynchronous
var sizeOf = require('image-size');
sizeOf('images/funny-cats.png', function (err, dimensions) {
console.log(dimensions.width, dimensions.height);
});
NOTE: The asynchronous version doesn't work if the input is a Buffer. Use synchronous version instead.
Using a URL
var url = require('url');
var http = require('http');
var sizeOf = require('image-size');
var imgUrl = 'http://my-amazing-website.com/image.jpeg';
var options = url.parse(imgUrl);
http.get(options, function (response) {
var chunks = [];
response.on('data', function (chunk) {
chunks.push(chunk);
}).on('end', function() {
var buffer = Buffer.concat(chunks);
console.log(sizeOf(buffer));
});
});
You can optionally check the buffer lengths & stop downloading the image after a few kilobytes. You don't need to download the entire image
Command-Line Usage (CLI)
npm install image-size --global
image-size image1 [image2] [image3] ...
Credits
not a direct port, but an attempt to have something like dabble's imagesize as a node module.
