[REBOL] Re: REBOL/Power-Tools/Graphics INVERT-IMAGE function!
From: robbo1mark:aol at: 1-Mar-2001 9:34
Your solution is much more elegant in it's use of the visual interface dialect effect
'invert, however what I was trying to show that is indeed still possible to write graphics
routines and functions that albeit slower are still functional using basic core commands
without using black-box functions like the VID in-built effects.
Hope this clears the confusion.
