You don't want to create a 24,832,000 element array in the ImageJ macro
language. Each element requires 36 bytes, so a 24,832,000 element array
would require 852MB! In a plugin, a 24,832,000 element byte array would
require only 24MB. Plus you would be able to access the elements at
least 100 times faster.
