  8. # Introduction:
  9. #   This is a very basic script I wrote to help myself split up one of them big
  10. #   icon sheets into individual files. After admiring its niftiness for a sec, I
  11. #   realized someone else may get some use out of it as well, so here it is.
  12. #
  13. # Features:
  14. #   - Extremely simple to use.
  15. #   - Splits large icon/sprite sheets up into uniform images, then saves them as
  16. #     individual files in a matter of seconds.
  17. #   - Can seperate any image into pieces of any size.
  18. #   - Combines many images of any size into one single file
  19. #   - Lightweight and fast
  20. #
  21. # Instructions:
  22. #   - Place script in new project or temporarily in an existing game anywhere
  23. #     before "Main"
  24. #   - Make any needed changes to the few configurations at the top of the script
  25. #   - Run the game
  26. #
  27. # Credits:
  28. #   - ForeverZer0, for the script
  29. #
  30. # Author's Notes:
  31. #   - Report bugs/issues at www.chaos-project.com
