Anybody know of a program that can tell me the area of a certain shape that I give it? I've got an NMR spectra with a series of peaks and I need to get the relative areas under these peaks. I don't have enough information to perform an integration.

I figured I could clean up the image, close in the area, and hopefully find some program that will let me "paint bucket" in the enclosed space and give me some kind of area measurement for the amount of pixel space I filled up, or whatever.

My only other option is cutting these suckers out with scissors and weighing the pieces of paper on an analytical balance...

I need the area of each group of peaks, so I would need a total of 3 areas.

Heres a scan...
