Zlib inflation

I'm attempting to inflate a zlib compressed file. Performing:

(InflateStream on: ((FileDirectory default fileNamed: 'filename')
binary)) upToEnd

raises a bad block length error. John McIntosh's tiff support package
in squeakmap contains zlib support, but it reports 'no installer
found for package' (I'm using squeak 3.9.)

Any recommendations for decompressing zlib files inside squeak?

Thanks, Brian.

Re: Zlib inflation

Use ZLibReadStream not InflateStream. InflateStream only implements the
algorithm (LZ) not the actual file format (ZLib, GZ, Zip, etc).

Cheers,
- Andreas
