I'm trying to access the pixel data of a jpeg in processing...the goal is to get an array of values that i can then use as input in another language....I've come across a lot of related info in the documentation, but can't quite piece together the code.  If anyone has a suggestion on how to start, I'd be very grateful!  Thanks.
