[SciPy-user] box extracting

[Eric Joseph Bubar]

Hello,
I am new to computer programming and python.  I have been using it for 
around 4 weeks, so my knowledge is VERY limited.  I have a 512x512 
image.  I want to take a boxed chunk of this image to analyze with the 
2D FFT.  Basically I need to make a box of this image of dimensions 
(100x100) centered on the middle of the image.  Everything out of this 
box, i want to get rid of.  Any advice on how to do this would be 
greatly appreciated.  Thanks
