'2': 'Invalid Parameter - -resize\r\n',

[LingboTang]

I'm running the resize.js example on windows 10 using node. And I got this error:

{ '0':
   { [Error: Command failed: Invalid Parameter - -resize
   ] code: 4, signal: null },
  '1': '',
  '2': 'Invalid Parameter - -resize\r\n',
  '3': 'convert "C:\\Users\\ltang\\Documents\\GitHub\\testMyGM\\imgs\\Balls.jpg" "-resize" "58x50%" "C:\\Users\\ltang\\Documents\\GitHub\\testMyGM\\imgs\\newImage.jpg"' }

And this is how I modified the resize example

var gm = require('gm').subClass({
    imageMagick: true
});

var currentDir = __dirname + "\\imgs";

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

console.log(currentDir);

gm(currentDir + "\\image.jpg").resize(353, 257, "!")
        .autoOrient()
        .write(currentDir+"\\newImage.jpg", 
        function (err) {
            if (!err) console.log(' hooray! '); console.log(err);
    });

Is there anything wrong with my syntax and how can I resolve it?

@LingboTang I have the same problem ... Did you find a solution ?

    var thumb1280 = task.target.replace('.jpg', '-1280.jpg');

    var resizeThePhotos = function(targetRelativePath) {

        var target = path.join(__dirname, '..', targetRelativePath);

        gm(target)
            .resize('1280')
            .write(thumb1280, function (err) {
                if (!err) {
                    //console.log(target + ': 1280 done');
                }
                else {
                    console.log(target, err);
                }
            });
    };

I get { [Error: Command failed: Invalid Parameter - -resize] code: 4, signal: null }

No I didn't fix the original, it must be some syntax problem. But I did some kind of hack, and I made gm successfully thumbnail images in S3 bucket. How I did to make it work is to include imageMagick:

var gm = require('gm').subClass({
    imageMagick: true
});

other than that, you should also define your .resize() function as a function that would be used to define .size():

gm(response).size(function(err, size) {
          var scalingFactor = Math.min(myWidth /size.width, myWidth / size.height);
          var width = scalingFactor * size.width;
          var height = scalingFactor * size.height;
          var index = key;
          this.resize(width, height).toBuffer(
                 'JPG', function(err,
                       buffer) {
                       if (err) {
                           next(err);
                       } else {
                           next(null, buffer, key);
                       }
         });
});

OK ... I reinstalled ImageMagick checking legacy tools got a different error ... so decided set it to false instead of true and it works now.

var gm = require('gm').subClass({imageMagick: false});

@gablablle Ok, that's interesting, I don't know where exactly cause the problem. I think there should be some explanation about this. I'll keep this issue here.

I had a similar issue and had solved the issue by making sure I installed the legacy utilities.

[madneal]

@mattbajorek Hi, I have tried to install imgamagick. But I have not seen the install legacy utilities. Which version you have installed, I selected verison ImageMagick-7.0.7-2-Q16-x64-static.exe.
