Phil, I checked PIL, there, there is a method fromstring(mode, data)
geting data from string, but when I used it( pass the voidptr), it said it
is invalid type. I think the data type is not memeory address, maybe
string. So there is no example code to show how to use voidptr object?
even I write a c++ extention, I still need know howto.
