Reference issue: Brotli compression #1236
Description
It looks like a new filter type could be added in the medium-term future. We can track that in this issue.
The formal technical specification for the new Brotli filter (BrotliDecode) in PDF 2.0 is still under development but will be completed soon. However, a selection of very simple PDF sample files using the new Brotli filter is provided now to help developers get a head start (ZIP file download).
