How to check an image dimensions using js or node
You can use image-size
npm module:
npm install image-size --save
Then can get dimentions like this:
var sizeOf = require('image-size');
var dimensions = sizeOf('./sample.jpg');
console.log(dimensions.width, dimensions.height);
For more information go through image-size
documentations
You can use GraphicsMagick or ImageMagick. I recommend GraphicsMagick as it's lot faster.
Install the npm package gm and use like this:
gm = require('gm');
// obtain the size of an image
gm('test.jpg')
.size(function (err, size) {
if (!err) {
console.log('width = ' + size.width);
console.log('height = ' + size.height);
}
});
