I'm writing a program that loads an image and then apply JPEG
algorithm on it.
I need to apply such algorithm only to a quarter of the image, possibly
selecting which quarter.
I don't really know how to divide in quarter an image in Java: I think
that if I can divide the image in 4 images then I can use each image
as a quarter, and apply the algorithm as I'm doing now on the original
image.
Can someone help me?
Thank you very much, and sorry for my poor english!
