Re: Extracting alphachannel from .pics

[Philipp Oeser <philipp.oeser(at)liga01.de>]

OK, forget about the registering, it works now (I guess because I called 
it directly once?!)
And at first it flipped the images upside down...
But when you change line 97 from
-------------------------------------------------------------------------
tmp = Image.frombuffer('L', self.size, buff[i::len(mode)]).im
-------------------------------------------------------------------------
to
-------------------------------------------------------------------------
tmp = Image.frombuffer('L', self.size, buff[i::len(mode)], "raw", 'L', 
0, 1).im
-------------------------------------------------------------------------
it works allright

Thanx again
Philipp
