Read "Pro Android Media" (published by Apress). It'll walk you through a
project that does what you're trying to build. :-) It doesn't SAVE the
resulting image, but it does a good job of explaining it.

Pro Android Media will show you things like using matrices to alter the
image, image blending (using PorterDuffXfermode), and so on. Most or
all of that is in chapters 3 and 4.

Then look at OpenCV if you REALLY want to get deeply buried in it....
(I might use it in my app, but I've got a lot of reading to do before
then, as well as a lot of work to do before I get that far...and for
various reasons that I've mentioned here enough times already, I can't
do that much in one day, so it'll be a while for me).

Later,
