Pointless?? Maybe so. I just need to squeeze all the speed out of it.

That is pointless. While the function isn't going to become faster, notice that it is inefficient. It cannot retrieve a single pixel, it has to retrieve a whole bunch of them and trow the others away.
So if you want your code to go faster, try to modify your code so that it accesses the pixels in a way so that you can integrate isPixelSet() into your function and reduce the amount of pixels wasted.
