So, as far as I understand, I can take the pole.(cpp|h) code (possibly synchronize often with libmso) and need to build my own library for handling HWP document. Thumbnailing and metadata extraction only needs to read some part of entire document, I can tune for that kind of processing in external program too.
Hope I can revive HWP backend for Calligra :) Regards, Park Shinjo 2013/1/7 <matus.u...@gmail.com> > Hi, > > compared to the latest version found at [1], the version of POLE inside > libmso includes a number of bug fixes and code to detect invalid and > corrupt files in the Windows Compound Binary File Format.
