If you could provide an interface which renders an EMF stream or file to ARGB (trancparency would be nice because I'm doing this with a dirty trick in the moment) then I could provide a codec which can be registered in libtiff for code 34719.

I've been working on an EMF renderer using Qt 4, which is nominally platform independent. It doesn't yet handle all record types, but I'm working through a range of examples, fixing as required. It lives in KDE's subversion repository: http://websvn.kde.org/trunk/playground/graphics/okular/emf/emf/ There is a small KDE dependency, but it wouldn't be hard to remove (just for visibility management). It would be hard to remove the Qt dependency. LGPL license. Patches / bug reports appreciated. Brad
