Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.
If you want some more advanced functionality, ImageJ is a create image library. It's open source and has plenty of examples.
The java2d api let you do this kind of thing. Is it too difficult to learn?
the standard API allows for all your needs.
You can find examples here.

I know you can use pHash from .NET or Java, but I would like a pure .NET (preferably) or Java implementation. Are there any others available? I am interested in the image hashing functionality specifically.
A perceptual hash is a way of creating a numeric hash of images and then being able to compare those hashs to see if the images are similar. It allows for really fast image recognition.
Here is an Java implementation of pHash for images by Elliot Shepherd.

i am wondering if there is any opensource and freeware solution to extract roads from an image, like google map images?
i think it maybe possible to code something like that with AI solutions, but i dont know where to start
thnx
If you're mainly interested in the results, instead of an algorithm, you may want to check out OpenStreetMaps.
Otherwise, you should focus on computer vision solutions and a framework such as OpenCV in order to process raw imagery and filter out streets based on their features – which is not trivial.
This sounds like it would be a valuable resource to cartographers ranging from 'street directory' publishers to the military.
I'm sure proprietary commercial software exists, but open source and freeware — probably not.

I need a tool for generating control flow in java, but not a visual draw, something that I can work with like with path conditions or so.
Anyone ?
To future record, what I´ve found that best suits to my needs is Soot.
http://www.sable.mcgill.ca/soot/
The ASM library can do that, at the JVM-bytecode level. See Method Analysis and Control flow analyses in http://download.forge.objectweb.org/asm/asm4-guide.pdf (page 121).
Atlas is an Eclipse plugin that enables program analysis. It has a querable graph database that includes the control flow graph (as well as data flow and other relationships).
Maybe this is what you were looking for http://www.jboss.org/jbpm

I'm looking for some framework to build an interface like Turbo C.
Six years later, you can consider (for Scala 2.12+) Tenchi2xh/Scurses
Scurses and Onions are frameworks for drawing nice things in your terminal using simple, elegant Scala. Scurses provides a low-level drawing and event handling API while Onions provides a high-level UI API with useful widgets.
How about a Text User Interface peer for the AWT: http://www.bmsi.com/tuipeer/
Other TUI libraries include JavaTUI and CHARVA
CHARVA is probably your best bet.
Take a look at JavaCurses library.

I'd like to set up a large linear programming model to solve an interesting problem. I would be most comfortable in Java. What tools/libraries are available?
There were several suggestions from an earlier question that I posted:
CPLEX
Dash
OptimJ
COIN-OR
lp_solve
and possibly more...
I used lp_solve with success. It looks like there is a native Java API, but I've only used the text file interface. It supports the semi-standard MPS and LP file formats, which I found more convenient for trying out different solvers (such as glpsol).
Currently, google digs up this Java Linear Programming libs:
