Issue/Question: Command failed: convert.im6: delegate failed html2ps + no image defined

Hey guys,

I'm not too sure what's happening here. I'm running imagemagick through the npn gm module in nodejs (v6)


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

var file = "/absolutepath/dis.png";
var targetFile = "/absolutepath/300px-dis.png";

if (!fs.existsSync(file)) console.log("WARNING:  FILE DOES NOT EXIST");
gm(file).resize(300).write(targetFile, function(err) {
              if (err) {
                console.log("[KO - RESIZE 300]", err);
                return callback(err);
              }
});

The command fails with the following error message:

    [KO - RESIZE 300] Error: Command failed: convert.im6: delegate failed `\"html2ps\" -U -o \"%o\" \"%i\"' @ error/delegate.c/InvokeDelegate/1065.,
    convert.im6: unable to open image `/tmp/magick-dEhsHcmz': No such file or directory @ error/blob.c/OpenBlob/2641.,
    convert.im6: unable to open file `/tmp/magick-dEhsHcmz': No such file or directory @ error/constitute.c/ReadImage/583.,
    convert.im6: no images defined `/absolutepath/300px-dis.png' @ error/convert.c/ConvertImageCommand/3044.,,
    at ChildProcess.onExit (/nodejsAction/node_modules/gm/lib/command.js:301:17),

What troubles me is that I'm pretty sure this code used to work a while ago. A guy refactored part of this method but I don't think he altered the gm-related logic... Then again, I'm running it on bluemix OpenWhisk so it's perfectly possible that the have made an update on the provided gm package that would be initiating this problem.

The other thing is I don't really know why html2ps should be involved as file is a png file.
I don't get the warning message in the console so it means file does exists.
I am using absolute paths, which I make sure they exist earlier in the process

I really don't have a clue where and how to proceed so I was wondering if you could point me out to the right direction.

Thx
