I was wondering if it is possible to change the filter used to write to
or read form a file without closing/reopening the file? The usecase is
reading/writing matlab files, which contain zipped blocks within a
context of unzipped data. So I would need to be able to switch on
compression once such a block starts and switch off afterwards, and it
would be nice not to have to ftell/close/create appropriate stream/open/
fseek every time.

Best

Daniel
