Drawing a chessboard using Stack Tools

A really non optimized way for Drawing a Chessboard but a good opportunity to explore the functions available in Image > Stacks, specially those located in the submenu Stacks > Tools.

In this algorithm, we use three functions available in Image > Stacks. They are:

• Image > Stacks > Images to Stack
• Image > Stacks > Tools > Concatenate... In this function, the two stacks can be the same. You don't need the duplication of the original stack.
• Image > Stacks > Tools > Reverse

 Fig.1: Steps to create the chessboard from two black and white cells

The algorithm described in the scheme of Fig. 1 is the following:

1. Create two cells: one in black and the other in white with newImage(...).
2. Create a 2-slices stack.
3. Concatenate two 2-slices stacks.
4. Concatenate two 4-slices stacks to create a 8-slices stack: yes ! you get your first row.
5. Duplicate the row and reverse the order of the cells.
6. Then, concatenate the first two rows of the chessboard (16-slices stack).
7. Finally, proceed by successive concatenation to get a 32-slices stack and the 64-slices stack. 
8. To see the chessboard, compute a montage of 8 rows per 8 columns. Et voilà.

Here is the script

These functions are really useful to edit small videos loaded as stacks (maybe the subject of a post).
