while doing research for this problem:
http://groups.google.com/group/pyglet-users/t/8c22362715cbade4
i found out that instead of writing:
rows = re.findall('.' * abs(pitch), data, re.DOTALL)
its MUCH faster (jump from 4fps to 20fps) to do:
rows = [data[i:i+abs(data_pitch)] for i in xrange(0, len
(self._current_data), abs(data_pitch))]
the memmove and reverse() calls are quite fast compared to this one.
there are some occasions in image/__init__.py where the re module is
used for string splitting and where using slicing seems to be faster.
hope this helps!
