Any one tell me to how to get image information using NodeJs module 'gm' . Here i used below code for re-size. But if image is smaller than re-size size than does not re-size so, that i want validation for image width and height so that purpose i want to get image information.

gm(main_url_path)
.resize(size, size)
.write(compress_path, function (err){
    if(!err){
        callback(compress_path);
    }else{
        console.log("Not Compressed success !!"+err);

// output all available image properties
gm('/path/to/img.png')
.identify(function (err, data) {
  if (!err) console.log(data)
});

Edit

If you want to know basic implementation of NodeJS packages, visit the npm website as it generally provides examples of the essential functions within the package: https://www.npmjs.org/package/gm
