Are there options for image manipulation without using the java.awt.* package?

Question

Java

There is a server application in Java that accepts image files via http.
The image needs to be resized, saved and made a few previews. All solutions to the problem come down to using the java.awt.* package, in particular BufferedImage. It is not clear why in a headless application to use GUI packages? Is there an explanation for this, or can anyone come across the implementation of a task without GUI classes?
