I believe that's backwards; the pixels are arranged from left to
right starting with the highest order bit. Something like this should
work better:
byte = (byte & (0x80 >> bitOffset)) ? 255 : 0;
I haven't tried running your code but I think this will at least get
it closer to working. (You could also optimize the speed by storing
the mask and offsets in variables rather than repeating the
multiplications, etc., for each pixel.)
