  1. Thanks for this interesting topic, in particular such a one like me who deals with image processing and related algoriths and a Delphi/FPC lover. In my tests, the reference pixel-accessing code is the fastest one, and the difference on a bigger image (12000*8143 pixs) is more clear, please look at the results below (running two times successively). Additionally, I've tested FastMM4 and FastMM5 on these testes, and FastMM5 is clearly yielded the fastest time scores (here I did not give the FastMM4 scores), and I've used FastMM5 in my tests.
