Error: Image given has not completed loading

I'm getting the following error when running imagediff on the command line.

$ imagediff --diff "file_a.png" "file_b.png" "~/Desktop/file_diff.png"

/usr/local/lib/node_modules/imagediff/imagediff.js:113
    context.drawImage(image, 0, 0);

Is this still an issue? Looking at the code, the image is used synchronously without waiting for it to load: https://github.com/HumbleSoftware/js-imagediff/blob/master/bin/imagediff#L50

This seems to work in most cases, but could explain your report.

It never ended up working, so I went straight to working directly with ImageMagick.

--diff wasn't supported.

There's still some issue with async loading (#31, #35, #39) but I'm calling this one closed!
