FTW files are projects that come from a genealogy software called Family Tree Maker and it is actually only this software that can be used to export the visualization of family trees from the projects to PDF format.
The same can be perhaps with any other genealogy software that supports import of .ftw files, but usually GEDCOM formats are used for exchange purpose and native formats from individual genealogy software are used only used in these.
