I need to resize the image.So in the below three libraries how to find which one is taking less time to resize the image.

https://github.com/rsms/node-imagemagick

https://github.com/mash/node-imagemagick-native

https://github.com/aheckmann/gm

Sample code

     var im = require('imagemagick');
     var sourcePath='/tmp/Images/1.jpeg';
     var destinationPath='/tmp/ResizedImages/resized.png';
     im.resize({
       srcPath: sourcePath,
       dstPath: destinationPath,
       width:   90,
       height:100,
   },function(err,res){


    if(err){


        console.log('Error while resizing image '+err);
        return;
    }

    console.log('Image resized successfully...');


});

I have been investigating the same question myself. Here is a benchmark of different software to do image resizing:

Personally I would suggest that you use the https://github.com/aheckmann/gm library, because it runs approximately 1.5-5 times faster than imagemagick according to this:

Good luck, I went for graphicsmagick myself.
