What kind of trash software engineers you got working on this? Reverse your arrays once you read them in from .png files. all of my images were flipped, because you read the arrays backwards. use a reverse iterator.... maybe..... What is this written on???? its slow... super slow.... like interpreted slow. your margins are wrong...
you either didnt know how to write the tools, or you didnt understand how the tools work. you definitely should learn to program in a faster language, because it doesnt work for your app. check you arent copying stuff when you shouldnt, and make sure you are allocating right. Im deleting this trash software as soon as possible.
These criticisms and the input on reversing your array come free of charge.
