我使用https://github.com/aheckmann/gm来调整图像大小.

var fs = require('fs');
var gm = require('gm');

var input = __dirname   + '/input.jpg';
var output = __dirname + '/output.jpg';

gm(input)
  .resize(350)
  .stream( function(err, stdout, stderr) {

    var writeStream = fs.createWriteStream( output, { encoding: 'base64' } );

    var i = '';

    stdout.on( 'data', function(data){

      i += data.toString('base64');

    });

    stdout.on('end', function(){

      writeStream.write( new Buffer(i, 'base64') );
      writeStream.end();

    });

  } );

问题是它不是在写整个图像.
