I was looking at the new ExtractorObject in PB 2019. I found a use for it extracting a string from a blob that was GZip encoded by another non-PB program.
The problem is that I want to do the same in PB 2017.
I looked at the Windows Compression API but it doesn't appear to support GZip. I am wondering how the ExtractorObject works so it can be reproduced in PB 2017.
