I don't quite follow. I understand (well, I think I understand) how a buffer works. The problem is that the length is wrong. As shown above, the length of f is 2048. If the array was being returned correctly as a buffer, then the length should be 3145728 (2048 * 1536). _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
