Java image manipulation

[sejong510]

I've been looking through Graphics, Graphics2D and can't seem to find
what I need.
I'm looking for a method that takes an image and 4 coordinates that
identify a subset of that image.
But all the methods that I find are restricted to a rectangular shape.

Is there a method that takes in an arbitrary 4-sided shape subset of
the original image and outputs those pixels in a rectangular shape?

i.e. I have a 100x100 image. I want the subset of (0,0),(0,50),
(100,0),(100,25) of the original image to be sampled and outputted to
a new 100x100 image.

Thanks.

Look at the AffineTransformation class.

Thanks for the response, but in my original post I stated a NON-
rectangular transformation.

Daniel, its almost what I need but unfortunately the coordinates are
not restricted to an affine transformation. A method that would allow
projective transformations would be great.
If anything, I can just go through the image and resize it by assuming
each column is an image 1 x height and stitching it back together.
Was just wondering, if there was a built in method to do this.
