Answer 1

The Google App Engine has a great built-in Images API for image processing tasks. For filesystem emulation on the Google App Engine, have a look at GAE VFS

In short, the way you are trying to accomplish your goal is inconsistent with the design of the App Engine.

Answer 2

so can someone tell me how to implement those functions in GAE?

The simple answer is that it is not possible in GAE.

Answer 3

GAE does not support java.awt images. You have to use GAE Image API to work with images. Reference: https://developers.google.com/appengine/docs/java/images/

This API operates with bytes. The source/destination of your image data can be: post from form, URL connection, DataStore BLOB or BlobStorage.

Answer 4

If the usual built-in packages aren't available, you could try Jimi, which is a pure Java image processing library. It hasn't been updated in the best part of a decade, but it should do the job. No school like the old school.

Answer 5

For some seasons, when you are using external libs already using BufferedImage behind the scenes the GAE's ImageService is useless. I have googled out https://github.com/witwall/appengine-awt but haven't tryed it yet. i believe it is enough to just add the dependency of this lib to the project to make it working.
