GM Error on running mediagen about cordova-media-generator

[ashwiniramesha]

I faced this issue. Here's what I did:

1. Checked PC advanced settings to see if I had installed the binary properly and it showed the path in PATH env variable.
2. restart the console after running npm install gm and then try "gm" command
3. run "npm install" to install dependent modules

Hi,

You might need to install graphicsmagick

On OSX

brew install graphicsmagick

Not sure how to do it on other OSes

installed graphicsmagick with brew and still getting this error

Error writing file to disk: Error: Could not execute GraphicsMagick/ImageMagick: convert "-size" "nullxc0b76e221b45d440d4de66b6f35c42df.JPG" "-resize" "760" "public/images/uploads/c0b76e221b45d440d4de66b6f35c42df.JPG" this most likely means the gm/convert binaries can't be found

trying to do resize an uploaded image for a single image first, I am using multer with this, and it put pictures in an array regardless of how many pictures there are according to my settings, here is my code:

if(req.files.image){

  //get properties of files beings uploaded

  var profileImageName      = req.files.image[0].name;
  var profileImagePath      = req.files.image[0].path;
  var buffer                = req.files.image[0].buffer;
  console.log(buffer);
  gm(buffer, profileImageName)
        .resize(760)
        .write(profileImagePath, function(err) {
          if(err) {
            console.log('Error writing file to disk: ' + err);
          }
        });


} else {
  //set default image
  var profileImageName = 'noimage.png';
}

when I console.log(buffer), I get null. Any tips on how to access the image and resize it? I dont want to save high resolution pictures and have my users use up their mobile bandwidth when using my app/site.

Thanks!

brew install did not work for me too. I had to install gm with npm to make that error go away.

npm install -g gm

[tarekshumaila]

I still see the same error, installed it with sudo npm install -g gm

:/

hi @tarekshumaila

By the same error does it still contain:

this most likely means the gm/convert binaries can't be found

I am by no means an expert on this, but after a fresh reinstall on a new machine the other day, the only thing I needed to do was install graphicsmagick using brew and it fired up. Maybe try using brew to uninstall it and reinstall it to see if that helps, and check for any errors on installation and report back?

Grrr... I had --> gm = require('gm').subClass({ imageMagick: true });
when I am using graphicsmagick.. so to resolve it, I had to declare it as this.

var gm = require('gm');

In my code I had to change few things to get the picture to resize properly

if(req.files.image){

  //get properties of files beings uploaded
  var profileImageName      = req.files.image[0].name;
  var profileImagePath      = req.files.image[0].path;
  gm(profileImagePath)
    .resize(353, 257)
    .autoOrient()
    .write(profileImagePath, function (err) {
      if (!err) console.log(' hooray! ');
      else console.log(err);
    });

} else {
  //set default image
  var profileImageName = 'noimage.png';
}

-- this will handle one picture... will dig deeper in the code to get it to work for an array of pictures.

rknell - thanks for your help, it did point me to the right direction.

Cheers!
