Use mash/node-imagemagick-native instead of CLI?
Instead of using CLI calls to run imagemagick, maybe use mash/node-imagemagick-native.
Avoiding CLI could greatly reduce complexity and potential errors. This needs to be evaluated.
The following diskussion might be helpful: https://github.com/mash/node-imagemagick-native/issues/46
But in theory, the native client should be much faster and on bigger files, it should have the same performance like the CLI.
mash/node-imagemagick-native does not support cropping parameters, yet. There is an issue for that, though: https://github.com/mash/node-imagemagick-native/issues/52
Since converjon is probably mostly used to scale big source images down to thumbnails or web gallery versions, is should profit more from the performance characteristics of imagemagick (CLI).
Closing this issue for now.

It also seems like node-imagemagick-native doesn't support cutting out specific parts of the source image. That is necessary for converjon's cropping.
