Many things in Java, especially graphics operations, are implemented
mainly by native code. I've traced 2D graphics calls all the way down
to very specific JNI calls for particular transformations or bitblit or
whatever. So, there's often little point in writing your own native
code to implement something that the libraries already do since often
they are well optimized. If you want to do something not already
included, then it can make sense to go native.

Can you Plz elaborate the "methods" and "this" in your last sentence --> "There are *fast built-in methods* to do *this* well,
but basically you create a pixel from a weighted average in color space of the pixels that the resulting pixel overlaps"
a ltmgfy link will be great !!!
