To Use

+

+

    +
  1. navigate to slice.sh in your terminal and do +
    + 
    $  chmod 775 slice.sh
+$  ./slice.sh Sunset.jpg 800 600 16 16
    +
    2. +
  2. replace Sunset.jpg with your image name.
    3. +
  3. vars: Image Height, Image Width, Vertical Divisions, Horizontal Divisions
    4. +
