I believe, the term 'binary data' in this context refers to numerical data -- e.g. floats and ints -- in the sense that it is not ascii or other text. Blosc is especially well suited for this kind of data due to its optional shuffle filter. This filter will re-organize the bytes in the data that is to be compressed in order of significance. For this filter to work, each data value must be composed of multiple bytes, e.g. int64. For data values that are composed of a single byte, e.g. int8 or char, the filter does not work so well. Hope that helps, V- _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
