Fatal error: Cannot read property 'width' of undefined

[boennemann]

Thanks for reporting David,

are you using the latest version of this plugin? We released 0.3.0 about a week ago and it should fix this issue (with imagemagick).

[DavidKk]

thx ^_^

I'm getting same error after processing the 10th image of a directory of 4000 images.

OS: OSX 10.9 imagemagick 6.8.7-0 grunt-image-resize: 0.3.0

here's grunt config:

image_resize: {
        options: {
            width: 100,
            height: 100,
            overwrite: true
        },
        organisms: {
            files: [{
                expand: true,
                src: ['../photos_src/organisms2/**/*.jpg'],
                dest: '../../photos/organisms/'
            }]

        }
    },

Could you please run grunt image_resize:organisms --stack?

[johowie]

here's the output as requested $ grunt image_resize:organisms --stack

I believe that Imagemagick has issues with reading/parsing one of your images. I just made a commit that outputs the original error and tells you which image is affected. Maybe you can try that.

[dwilt]

I'm currently having this issue as well.

[thusoy]

I'm seeing this as well. Suspected large images to be the issue (5600x3600), but it failed also on a smaller resized version (1200x768).

[normanrz]

By any chance, could you send me the image files? If I had some images where the error occurs, it would greatly help me debug.

[thusoy]

Sure, try this one: https://www.dropbox.com/s/xol3qq819cvewx9/_TKH4341.jpg

[normanrz]

I made a test for your image in https://github.com/excellenteasy/grunt-image-resize/tree/issue-9 It passes for me both on Mac OS and Ubuntu. Which version of ImageMagick are you running?

[thusoy]

Windows...

[normanrz]

I wasn't aware this runs on Windows, too. Anyways, I just tried it on a clean Win 8.1 and it passed aswell.

[thusoy]

Hmm, tested my setup on a Ubuntu box, still failing, so I can confirm that it's not a platform issue. Will dig a bit more.

[normanrz]

Have you tried the test suite or do you use your own Gruntfile? Maybe it's not an issue with the file after all.

[thusoy]

Got it working, not an issue with either the plugin or the file, was the ImageMagick install in my case. First time around I didn't have ImageMagick installed (you might want to add in the readme a little note saying you should have that installed and on the PATH), but installing it didn't solve the issue either, nor did relaunching cmd or a reboot. Much bantering back and forth, crashed on Ubuntu for other reasons (gruntfile fail), removed ImageMagick and re-installed, and then it started working.

So to others struggling, make sure ImageMagick is on your PATH and working (test it by typing convert -help and you should get a long list of possible options, and then it should work.

To make it a bit easier to spot stuff like this in the future, you should probably add some error checking to your function calls, this was the line 71 gm(filepath).size call that failed, and the error object was passed to your function (and the size arg was thus undefined), so checking for err before using size could have at least provided us with a ENOENT error, which is thus easier to backtrack to a failing spawn, which again hints towards ImageMagick. :relieved:

[normanrz]

Thanks so much for investigating. The error handling is already in the master branch but not yet on npm. Maybe it's a good time to publish a new version. I added a section to the Readme for setting up ImageMagick.

[jeremybarbet]

I had this issue as well. I succeeded to fix it with install imagemagick and create the $PATH to the folder.

[netpoetica]

I also had this issue, seemed to be fixed following a brew update (mac osx)

[netpoetica]

Interestingly, in another repo of mine I am still getting this issue regardless of the brew update, although it was fixed in another repo (using same version 0.3.0 in both).

[ilovett]

On Linux Mint/Ubuntu... I was getting this error, and I THOUGHT I had imagemagick installed, but it turns out I didn't... I saw the note on it maybe being related to images which are too big, so I set out manually resize it by installing imagemagick command line tool convert

sudo apt-get install imagemagick

Once I had imagemagick installed, that fixed the said problem for the larger size image (6315x4000 pixels)

[GaryJones]

Had the same problem after installing ImageMagick with Homebrew:

brew install imagemagick

Tried re-installing, and got a warning that it was already installed, but not linked.

Uninstalled with:

brew uninstall imagemagick

Then installed again:

brew install imagemagick

And got an error that the brew link step did not complete successfully. Followed the instructions and did:

brew link --overwrite imagemagick

It reported 71 symlinks were created.

Run grunt image_resize and this time it worked successfully.

[caiobleggi]

Thanks @thusoy for solving this on Windows.

Just complementing the solution for who doesn't know to change the imagemagick path on Windows 7+. Be sure to change only the C:/Program Files/ImageMagick-(version) path to your grunt.js folder. (In my case, had many others values on the PATH variable).
