Integrating MarvinJ for image manipulation and data extraction

I'm looking into ways to efficiently access an images pixel coordinates and RGBA values. My js knowledge is way out of date and I have never used used C3's js scripting.

Before I go too deep into trying this, I was hoping someone could give an indication of whether it would work in C3 or not?

MarvinJ is a pure javascript image processing framework:

Script here: marvinj.org/releases/marvinj-0.7.js

The code I think would be useful to do an Alpha comparison per pixel is demonstrated here:

image = new MarvinImage();
image.load("yourimage.png", imageLoaded);

function imageLoaded(){
 console.log("(0,0): "+(image.getAlphaComponent(0,0) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));
 console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));
}
