I continue my hacking on symbian mbm(multi-bitmap) format.
# a helping function from struct import unpack def readL(f, pos=None): if pos is not None: f.seek(pos) return unpack('L', f.read(4)) # the real counting function def mbm_count(mbm_file): f = open(mbm_file, 'rb') mbm_type = readL(f) if mbm_type == 0x10000041: # mbm on ROM (Z:) return readL(f) elif mbm_type == 0x10000037L: # mbm on file (normal) return readL(f, readL(f, 16)) # read at trailer else: # what type is it? return NoneFor example (you may try this on your phone)
>>> mbm_count('z:\\system\\data\\avkon.mbm') 503L >>> mbm_count('E:\\system\\apps\\FExplorer\\FExplorer.mbm') 19L >>>
