Complementary RGB Color Pairs

[Wilhelm Sanke]

The zip-archive of the ImageData Toolkit - downloadable from page 
"Sample Stacks" of site
<http://www.sanke.org/MetaMedia> -  seems to be O.K. now from my side.
It is still unclear for me what has happened to the "kaput" archive.

For those who do not want to bother to download a big stack just for the 
matter of a few script lines
here is the script of btn "complementary colors" that at least gives you 
a hint how to proceed to find out
complementary color triplets:

"on mouseUp
  set the cursor to watch
  put the milliseconds into Start
  put the imageData of image 2 into iData
  put 0 into counter
  repeat for each char C in idata
    add 1 to counter
    put numtochar(255 - chartonum(C)) into char counter of idata
  end repeat
  set the imageData of image 2 to iData
  put the milliseconds - Start into fld "test"
end mouseUp"
