[/snip] To rotate an array 45 degrees (to the left) would be a difficult thing. You could write a script that could do it and it would not matter your array size. Consider the following as a thought experiment... How many rows in the array? Is the number even or odd? How many columns in the array? Is the number even or odd? Does the number of rows match the number of columns? Take the number of rows and divide in half. If the number is not an integer round it up to get the mid row. If the number is an integer, add 1 to get a mid row. Take data in (0,0) and place in (0, mid row#) of new array Take data in (0,1) and place it in (1, mid row#-1) of new array And so on.... Can it be done? Yes, it can. Is it going to take a while to figure out.....yes, it will.
