Handling portions of images which may be in different shapes

[forgetlosing]

Hi,
I am currently doing project where i need to let user mark portions of any inputed image.
The markings could be in different shapes like square, rect, circle, irregular etc.
I should be able to remember the markings and later on reproduce them on the same image when asked to.
Also i need to generate the bit map of those portions of images.
What language do you suggest?
I want to choose a language that is rich in libraries to handle images and enable me to do this?
How does C++ help? Eg: libraries etc.
Also are there any pre existing open source projects that handle images so that i can use that code?
Any help would be appreciated.

Here is a C++ image library that I found with a Google search: The CImg Library - C++ Template Image Processing Toolkit

Also, Java may be a good language to use because it has a ton of libraries that it comes with.
