Hi I have a 2D array of x*y integers assuming that x and y are multiples of 8 , how do I extract each 8x8 block ? and assume this 8x8 blocks to another 2D and store this in a datastructure I'm just stuck at the extracting each 8x8 block (storing to datastructure is ok) Any idea on how it should go ? Sorry if this sound stupid (I am slow in some things but I try my best) Thanks for any help! -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
