Hi: I took a look at pdf-stm-f-fax.[hc] and saw its interface wasn't agreeing with pdf-stm-filter.h nor the library arch doc, so I changed it. I'm using a hashtable to pass as argument the filter's configuration. Is that what you had in mind?
Would this be correct? I attach a tarball with the source. If it's correct, all that is left to be done is... the rest of the module :P Cheers, Gustavo.
