[Numpy-discussion] Help with bit arrays

Hello, what's the current status on numpy for loading bit-arrays ? I'm currently unable to correctly load black and white (1-bit) TIFF images. Code example follows: from PIL import Image import numpy from matplotlib import pyplot img = Image.open('oi-00.tiff') a = numpy.array(img) ^ does not work for 1-bit TIFF images PIL source shows that it incorrectly uses typestr == '|b1'. I tried to change this to '|t1', but I get : TypeError: data type "|t1" not understood My goal is to make the above code to work for black and white TIFF images the same way it works for grayscale images. Any help ?
