I'm creating a website using node.js. I have seen many libraries mentioned that piggy back on top of imagemagick etc. There is a list here: https://github.com/ry/node/wiki/modules#graphics

What I'm trying to do is take the image that a user uploads, crop it/size it to certain dimensions the site requires. What is the best/most active script to do this? I'd like one with npm support. Does anyone have actual experience using some of these?
