this is not a bug; for details on the intended behaviour, see the
description of "new" at:

hmm.  I cannot repeat this problem.  does the following
snippet work for you:

import Image
bitmap = (chr(0xaa)+chr(0x55))*4
im = Image.fromstring("1", (8, 8), bitmap, "raw", "1")

if it doesn't, you may have a build/configuration problem (e.g.
using 0.3b3's script library with 1.0b1's _imaging module is likely
to result in problems like this)
