It will also allow you (after formatting) to maintain a list of human readable
chunks of characters without necessarily maintaining the corresponding image
in that environment (eg that image may be in one of many substacks which are
not open). You can then compare the correspondingly formatted md5digest of
incoming images with the list to know if a copy exists. I think searching
through a few thousand lines will take less than a few seconds! Isnt rev
powerful?
This is a very good idea. To find a duplicate among n images will take n*(n-1)/2 comparisons. Comparing the md5 will be much faster. This will work either on binary files or on imageData() & alphaData() & formatedWidth().
You might even speed that up by sorting the md5 and looking that up or by using arrays.
